Roy Campbell

Roy Campbell was a former U.S. Army Colonel in command of special forces group FOXHOUND, who later worked for an advisory body under the UN Security Council to monitor PMC activities. Campbell was a close friend of Solid Snake, and the biological father of Meryl Silverburgh.

Early life and career
Roy Campbell served in the United States Marine Corps under the 5th Marine Regiment, working as a truck driver. However, he left after he and his younger brother both fell in love with the same woman. He stepped aside for his brother's sake, and used his joining the Green Berets as a convenient excuse, especially since he wanted to continue serving his country. At some point, he heard about the CIA FOX unit but assumed it was just a rumor.

In 1970, Campbell and a squad of Green Berets were dispatched by Fort Bragg to the San Hieronymo Peninsula, Colombia, to investigate a secret Soviet missile base that had been constructed there. However, the rogue FOX unit, which had taken control of the base, anticipated their arrival and ambushed them. Eliminating most of Campbell's squad and taking him prisoner, he was left the sole survivor, though he suffered a broken leg during the skirmish.

Campbell initially attempted to escape from his cell by removing screws that sealed off a ventilation cover underneath the bunk, but he was relocated to a different cell before he had the chance to use it. This left Big Boss, the next prisoner, with an easy escape method. The two joined forces to bring down FOX, who were being commanded by Gene. Though he could stand up and move around in a limited manner, Campbell's broken leg left him unable to support Big Boss directly during combat operations, outside of driving a stolen enemy truck. Both decided to recruit former Red Army personnel over to their cause, in order to help prevent FOX from launching a nuclear weapon into the Soviet Union. However, Campbell quickly became diagnosed with malaria and a significant part of the mission concerned locating anti-malarial drugs, so as to save not only him, but to prevent the rest of their fledgling group from falling ill.

After FOX's medical chief Elisa provided intel to the resistance, Campbell was initially suspicious, having had previous experience of women "sweet-talking [him] into getting [his] ass kicked." After the discovery of their use of Metal Gear, they attempted to halt the launch. After an initial mission to infiltrate the peninsula's main missile silo resulted in Big Boss's capture at the hands of Cunningham, Campbell briefly assumed command of the resistance group, and carried out operations to locate and rescue Big Boss. The group soon discovered the truth behind FOX's revolt and successfully destroyed their secret weapon, which they had dubbed the Intercontinental Ballistic Metal Gear, along with its test model, Metal Gear RAXA. Shortly after the end of the mission and his return to the United States, Campbell had to spend a long period of time in the hospital, including having to endure an annoying nurse.

Post-San Hieronymo
Roy Campbell went on to serve in Delta Force. He would also have an affair with the wife of his brother, Matt Campbell, from which his daughter Meryl would be born in 1987. Matt raised Roy's daughter as his own, but died before he could watch Meryl become a soldier. Roy was unaware that Meryl was actually his daughter, but shared a close relationship with her as an uncle. At some point, Roy got married.

During the 1990s, Campbell served as the executive officer of FOXHOUND, a special forces unit based on the resistance group he co-founded during the San Hieronymo Takeover, once again commanded by Big Boss. When Solid Snake joined the unit in 1995, Campbell felt nostalgic towards the young soldier due to his similarity to Big Boss. At some point, he discovered that Snake was Big Boss' son. After Big Boss was revealed to be the secret leader of Outer Heaven, and was subsequently defeated by Snake, Campbell was appointed as commanding officer of FOXHOUND and began revising the unit's methods with his personal touch. He discarded the codename system and adopted the use of high-tech equipment such as radars and spy satellites. By 1999, following Snake's retirement, Campbell was one of the few members of FOXHOUND to recall the unit's days under Big Boss. He also was awarded various titles during the late 1990s.

In December 1999, Campbell enlisted former FOXHOUND agent Solid Snake for Operation Intrude F014, during the Zanzibar Land Disturbance. With his supervision, Snake was able to defeat the forces of Zanzibar Land and retrieve the OILIX formula. When Snake encountered Big Boss once more, Campbell told the former to "put aside [his] personal feelings" for the man who had once been his CO, as he was "just another madman."

Post-Zanzibar Land
In the following year, Campbell retired as FOXHOUND commander.

Campbell eventually discovered that Meryl was his daughter at least a day before the Shadow Moses Incident, due to Matt's widowed wife informing him as such in a letter to him.

In February 2005, Campbell was called back to action by the United States Government when FOXHOUND, now led by Liquid Snake, took over a nuclear disposal facility on Shadow Moses Island, taking several people hostage. Among them was Meryl, who had been deliberately assigned to the facility by the Pentagon on the day of the takeover after having anticipated the revolt, and they used this to coerce Campbell into cooperating. Campbell once again brought Snake out of retirement to neutralize the new FOXHOUND, though the desperation of the situation caused him to send black ops soldiers to his home to capture him, much to Snake's annoyance. Snake reluctantly accepted, and Campbell directed his mission from on board the nearby Ohio-class submarine USS Discovery (submarine).

During the course of the mission, Campbell was forced to keep many secrets from Snake, including the true purpose of his mission and his injection with the assassination virus FOXDIE by Naomi Hunter, in order to ensure the safety of Meryl and himself. This resulted in a strain in Snake's friendship with Campbell, especially after Campbell also promised that he would brief Snake in full as a condition of him accepting the mission. Due to these constraints, Campbell became increasingly angered with the suspicious motives behind the operation, eventually coming to believe that the clandestine group known as the Patriots were behind the events.

Campbell eventually learned from data analyst Mei Ling that a member of their radio support team, Master Miller, was actually an imposter working for the Sons of Big Boss and was stationed within the base. The real Miller had died three days earlier, which Campbell had been unaware of due to his Codec link to him being cut, and thus was unable to warn Snake before he unwittingly activated Metal Gear REX.

After Snake successfully neutralized the threat from Metal Gear, Campbell revealed the truth of the mission to him and tried to call off an air strike directed at the base, but was subsequently placed under arrest by Secretary of Defense Jim Houseman. However, while he was detained, he managed to make contact with President George Sears and inform him of Houseman's actions, resulting in the Secretary being arrested for stepping out of line. After Snake defeated Liquid, Campbell was exonerated of all charges, as blame was laid on Houseman instead. In case the U.S. Government changed its mind, Campbell secured a copy of all the mission data recorded by Mei Ling as an "insurance policy," in order to protect her, himself, and Snake from arrest.

Campbell later revealed to Snake and Meryl that he was really the latter's father.

In April 2009, a man resembling Roy Campbell served as Raiden's commanding officer during the Big Shell Incident. However, this Colonel was later revealed to be an artificial construct created by the Patriots and generated by GW, the AI system on board Arsenal Gear.

Post-Big Shell
Sometime after the Big Shell Incident, the real Campbell became concerned for Raiden's well being, having at one point served as his actual commanding officer. However, Raiden avoided him, his resurfaced memories as a child soldier continuing to haunt him, and his frequent disappearances causing his relationship with pregnant girlfriend Rosemary to deteriorate. Fearing for the safety of her and Raiden's son, Rose collaborated with Campbell in devising a plan to shield the child from Patriot eyes, informing Raiden that she had suffered a miscarriage. With Raiden's subsequent departure, the two broke all ties to him and pretended to marry, freeing Raiden to carry out his activities against the Patriots. Campbell played out his new life to the fullest, not even telling his own daughter Meryl the truth, straining their relationship in the process. He also encouraged Rose to pursue a career in psychological counseling.

In 2014, Campbell, now working for an oversight committee in the United Nations responsible for monitoring PMC activities, contacted his old friend Solid Snake, along with his partner Hal Emmerich, after he had discovered the whereabouts of the long missing Liquid Ocelot. Not content with the UN and other governments simply ignoring Liquid's attempt to plunge the world into total war, in effect aiding the economy of the 21st Century, Campbell took the matter into his own hands and hired Snake to perform an assassination. Upon reaching the Middle East, Snake met up with Meryl, Campbell's daughter, who revealed to Snake that Campbell had remarried to Rose and she was no longer speaking with "that womanizing piece of shit." Campbell was visibly upset when Snake divulged his daughter's opinion of him, but Campbell had to keep the secret that his marriage to Rose was a sham up until Raiden was done with his mission in order to protect John. During a break from mission support duties, he attended a UN Swap Meet that dealt with ration tasting, in which America's rations were unanimously voted the worst, which he told Rose "over a hundred times" about and later relayed to Snake, hinting at Rose's poor cooking skills.

After the mission's completion, Campbell confronted Meryl in order to make amends with her after years of not speaking to her due to his deceit. He congratulated Meryl on her impending marriage to Johnny Sasaki, but she initially ignored him. Campbell began to walk away before Meryl pulled her Desert Eagle from her holster. He then returned to her, putting himself point-blank near the muzzle, and then pulling it to his own neck. She then released the magazine, forcefully telling him, "You're going to walk me down the aisle." Campbell laughed and told Meryl that finally, they had plenty of time to get to know each other. Campbell remarked how beautiful Meryl looked, making both her and Mei Ling, Meryl's bridesmaid, break down in tears. Campbell was last seen seemingly overhearing Otacon's conversation with Sunny in regards to Snake's whereabouts, and quietly thanked Snake for all he had done for him.

Personality and traits
During his youth, Roy Campbell was a loyal soldier. He was, however, hesitant in regards to combat. He once asked Naked Snake about whether it was all right to be afraid in battle, although he misinterpreted Snake's answer about how fear when used appropriately will aid a soldier in battle to mean that its all right to have a little cowardice on the battlefield. He also didn't appreciate it when higher-ups within the United States Government hid information from him for political reasons. He also had some fascination with girls, and was willing to give dating advice to his soldiers, although several times, he misinterpreted the soldier's questions regarding aspects of the battlefield for wanting advice on dating.

He was also shown to be a skilled strategist, having come up with some of the strategies in the Resistance, as well as leading the Resistance when Snake was captured until he and the other soldiers rescued Snake during the San Hieronymo Takeover, as well as his earlier mentioned restructuring of FOXHOUND after he took command due to Big Boss being unveiled as the leader of Outer Heaven and his presumed death in Operation Intrude N313.

Solid Snake found Campbell to be a poor liar. During the Shadow Moses briefing, Campbell claimed that he was involved in the mission because he was awaiting action in the military, before admitting that it was actually due to Meryl being held hostage. Indeed, throughout the mission, whenever Campbell attempted to express surprise regarding the FOXDIE virus and Metal Gear REX, Snake often suspected him of knowing more than he was letting on.

Campbell valued Solid Snake's friendship. Despite the numerous heated exchanges between Snake and Campbell during the Shadow Moses Incident, which were one sided on the former's part, Snake admitted to Naomi that he still considered Campbell to be one of his friends. This revelation surprised and relieved Campbell. It was due to this friendship that Campbell was able to get Snake to participate in the Zanzibar Land Disturbance, Shadow Moses Incident, and Liquid Ocelot's Insurrection. In the case of the Shadow Moses Incident, Campbell, due to being blackmailed by the Pentagon, was forced to hide important information from Snake concerning the mission despite it being one of the stipulations that Campbell agreed upon in order to get Snake to actually participate in the mission. This almost caused their friendship to be permanently strained until Snake found out the truth later in the mission.

He also possessed some religious beliefs. After finding out about Gray Fox's death he said "God rest his soul."

Unconfirmed history
Campbell met Master Miller while he was still in the Marines. Soon after he overhauled FOXHOUND's methods, Campbell became very concerned about the direction the unit was headed. He would later step down as the commanding officer of FOXHOUND when operatives were being genetically treated and enhanced.

Metal Gear 2: Solid Snake
Colonel Roy Campbell (ロイ・キャンベル大佐) first appeared in Metal Gear 2: Solid Snake. His in-game portrait was modeled after the likeness of actor Richard Crenna, who was best known for portraying Colonel Trautman in the first three Rambo films. The MSX2 version of Metal Gear 2 spelled his last name as "Kyanbel", although this was changed to "Campbell" in Metal Gear Solid. Later releases of Metal Gear 2 changed the spelling to "Campbell" for consistency. Campbell is the only character who originated in the MSX2 games that still bears a resemblance to the person that they were originally modeled after.

According to the user's manual for Metal Gear 2, Campbell was formerly known by the codename of Chicken Fox. However, due to his own statement in Metal Gear Solid that Gray Fox was the only FOXHOUND member to receive the codename "Fox," it is now considered to be non-canonical. The idea of Gray Fox being the exclusive holder of the name was first introduced in Metal Gear Solid, whereas the earlier games only state that he had successfully earned the title.

Campbell is assigned the contact frequency of 140.85, which remains consistent throughout the series. This frequency is also given to Major Zero in Metal Gear Solid 3, due to his similar role as mission commander.

Metal Gear Solid
If the player manages to quicky enter the elevator from the dock to the heliport at the start of Metal Gear Solid, Campbell will tell Snake "Excellent, Snake! Age hasn't slowed you down one bit!"

In the novelization of Metal Gear Solid by Raymond Benson, Campbell admitted to Snake that Meryl was his daughter after both Snake and Meryl made it out alive, something he only does in the actual game in the alternate ending where Meryl dies.



Metal Gear Solid audio drama
Campbell also had a major role in the non-canon audio drama for Metal Gear Solid, which took place after the main game. In the first part, Campbell has Snake dispatched to rescue Meryl after the latter ended up being caught in a chopper crash with UN Peacekeepers in the Basra Republic. He later ended up captured at the Estaria Republic in the third part, necessitating Snake, Meryl, and Mei Ling to conduct an unofficial rescue mission of Campbell. Campbell's artwork depicted him wearing a trenchcoat similar to that of Big Boss and Liquid Snake.

Metal Gear: Ghost Babel
In the non-canon game Metal Gear: Ghost Babel, Campbell got Snake out of retirement, citing that Galuade, the base belonging to the Gindra Liberation Force, was the same place that Snake partook in Operation Intrude N313. Campbell himself was blackmailed by Steve Gardner into participating in the mission with the threat of exposing his involvement in killing off Black Chamber. His reasons for retiring from FOXHOUND were also elaborated in this game, as he, under misinformation from "Anonymous" (a.k.a. Gardner), wiped out Black Chamber with the FOXHOUND unit, under the mistaken belief that they were terrorists, and didn't find out until after the fact. It's also hinted that Campbell's favorite drink is malt that is straight up and neat.

Campbell's Codec portrait in Ghost Babel was used later in Metal Gear Solid 2: Sons of Liberty when the Colonel's AI began to malfunction.



Metal Gear Solid 2: Sons of Liberty and Substance
The Colonel's likeness appears as an AI construct in the Plant Chapter of Metal Gear Solid 2, although the player and protagonist are initially unaware of this. The real Colonel Campbell makes a reappearance in Metal Gear Solid 2: Substance, during two non-canon Snake Tales.

In "A Wrongdoing," Campbell acts as Snake's mission operator after Snake is dispatched to the Big Shell to rescue the U.S. President from a hostage takeover that involved Fatman, and that Richard Ames and Jennifer are two people he should make contact with.

"Confidential Legacy" has Campbell calling Snake out of retirement after a tanker containing a Metal Gear from Eldera was hijacked by soldiers under Gurlukovich's employ. Campbell explains the reason he's hiring Snake is not only because he wants an ally in his vendetta against Gurlukovich that he had during the Cold War, but also because his niece, Meryl, is also involved in the takeover. After Snake learns that the Metal Gear was significantly older than he thought, and that Meryl was allied with the Gurlukovich Mercenaries for reasons relating to her father Matt Campbell, Campbell explains to Snake that Matt Campbell was involved in a top secret mission during the Cold War in Eldera, run by a pro-American dictator at the time, which involved the military conducting the top-secret project of developing Metal Gear in Eldera. The project ended up terminated around the same time the Cold War ended as well, but Matt ended up going AWOL when the Americans were planning to withdraw. He also explains that Matt was found dead, and that, because of America's withdrawal, the pro-American regime also collapsed and Eldera was plunged into eternal civil war from an uprising of minority groups (an action that was instigated by Spetsnaz groups under Gurlukovich's employ), he suspects Gurlukovich of personally killing Matt, explaining his desire for revenge against Gurlukovich (a suspicion confirmed by Gurlukovich shortly after Snake and Meryl fought each other). In the Meryl Lives ending, he debriefed Snake in the cell that was originally Meryl's cell, telling Snake that the Metal Gear was obsolete and a failure, worth less than scrap metal, and likewise its nukes were nothing more than cheap imitations, and that it was in fact Roy, not Matt, who was Meryl's birthfather, and leaves to tell Meryl the truth (something he also reveals in the similarly non-canon "Otacon" ending of Metal Gear Solid). Snake also realized upon learning this that Meryl's true lineage was the true reason behind Matt accepting the mission to Eldera as well as his being manipulated by Gurlukovich and then killed.

Metal Gear Solid 3: Snake Eater
During the Time Paradox Game Over screen in Metal Gear Solid 3, Campbell's voice can be heard chastizing Snake for killing Ocelot and EVA, as doing so would alter the future of the Metal Gear timeline.

Campbell, along with Solid Snake, makes a cameo appearance in the Snake vs. Monkey minigame that is included in earlier releases of Metal Gear Solid 3. The Colonel briefs Snake about his newest mission to catch experimental mechanical monkeys, much to Snake's dismay, who responds angrily that Campbell could have gotten someone else to do the job and frustrated that he had to be brought out during vacation. Campbell then explains that Otacon has connections with the person who is involved with the monkeys and it was Otacon who recommended Snake. According to Campbell's personal data, his hair and eye color was brown, his height was 6 ft. 8/5 in, his weight was 187 Ib, and his blood type was "A."

Ape Escape 3
Colonel Campbell appears in the Ape Escape 3 minigame Mesal Gear Solid. In it, Campbell calls the Professor via Codec to ask him to send one of the main protagonists of the series to find Solid Snake, who has gone missing. The Professor tells him that they are unavailable, so he decides to train a monkey (Pipo Snake) instead. Campbell's English voice in Mesal Gear Solid was provided by Michael McColl.

Metal Gear Solid: Portable Ops
"A survivor of the Green Beret unit dispatched to the San Hieronymo Peninsula, he was rescued by Big Boss and subsequently joined forces with him. Provides mission support to team members from his truck."

- Character description in Metal Gear Solid: Portable Ops Plus

In Metal Gear Solid: Portable Ops, the young Roy Campbell wears camouflage clothes, which are identical to the Tiger Stripe camo in Metal Gear Solid 3. If Snake attempts to contact Campbell a few times during a mission, he will sometimes give Snake hints on how to get a girl (under the guise of giving him advice to control and command his troops). If the player controls a recruit, he also talks about how he and his brother were in love with the same woman (which may be Meryl's mother) but insists that she didn't dump him. Some of his calls also have him misinterpreting the soldiers requesting for advice in regards to getting close to the enemy or being ambushed as asking for advice on dating.

Due to Campbell's physical and medical status during the San Hieronymo Takeover, he is the only main character in the original release of Portable Ops that is not playable in the main game. However, players can unlock Campbell in the expansion Metal Gear Solid: Portable Ops Plus by completing the Infinity Mission under extreme mode. He comes with an M16A1, and his career is Headhunter, which allows him to detect the enemies abilities. When unlocked, a message will state that Campbell's leg has healed in place of the usual "A new soldier has been recruited" message.

Kojima, when doing commentary on both Portable Ops and Metal Gear Solid 4, also admitted that Campbell's first scene in the latter game was intended to mirror his meeting Big Boss in the former game.

Portable Ops Plus
Roy Campbell effectively acts as the mission controller for the game. When starting the game, he talks to the player as if the player was newly recruited into FOXHOUND, and sends him on a drill mission, also requesting that the player find recruits all the way. He also briefly references The Boss's beliefs when explaining the need for recruitments. During the Easy mode, he'll also give some details relating to the basics of the game, including access points and where to find one, as well as supply his radio frequency; how to knock out, steal from, and drag a soldier to a truck (with Campbell also implying that they stole it from the enemy again, and also reacting with some confusion towards the player character's remark that there's an arrow above the truck) as well as general guidelines for special missions in general; midpoint breaks; infiltrating with player characters of the same type as the enemy as well as finding Kerotans, box recruiting, enemy strengths being viewable from FPV via stars (not to be confused with the knock out stars) and withdraw points; knowing the current location of the enemy; and some details about the final mission. Afterwards, he'll briefly explain what happens when soldiers gain titles throughout the mission; the Headhunter ability (because a member of the team joined who possessed Headhunter); recruiting people to the spy, medical and technical units; and will also compliment the player every time they first clear the difficulty levels from normal to extreme. In addition, he'll also report that a new soldier possessing a "Headhunter" ability, an older guy who reminds him of [Naked] Snake, and a younger guy wielding a Katana joined the unit after clearing Easy, Normal and Hard mode, respectively. If the player tries to start Extreme, Campbell will also briefly try to talk the player out of it as he doesn't wish for the player to throw their life away, although he relents after he learns that the player wants a challenge, although under the condition that the player withdraw should they face too much difficulty. As noted above, the player can unlock Campbell as a playable character after clearing Extreme for the first time. After completing Extreme mode, he'll briefly express shock that the player actually managed to make it through their mission and survive, and mention that the player was a "credit" to the unit, although he'll also credit himself for helping the player achieve the mission before requesting that he return to the group. He'll also express some brief regret that he wasn't able to show the player the ropes in person due to his broken leg. Afterwards, a message will pop up stating that Campbell's leg has healed. He'll still express some shock that the player made it back, although he quickly corrects himself and states they knew he'd do it, although he's glad that they are allies and not enemies. When first procuring certain items, such as the Textbook/Handbook and the Fulton, he'll call in via an auxiliary call to explain their functions. In addition, his reaction to finding a prisoner, depending on their appearance, will vary. If the player found a regular enemy as a prisoner or Johnny, Campbell will mention rescuing the prisoner and having him come back to the truck. If the player finds a unique character (e.g., any of the main characters from Portable Ops, plus Raiden and Old Snake), he'll react to their presence as if they had either gone missing/gone AWOL, or had somehow survived a battle that was believed to have gotten them killed.

Metal Gear Ac!d
Colonel Campbell is briefly mentioned by Roger McCoy, where he explained that Solid Snake was chosen to partake in the mission on Lobito Island under Campbell's recommendation. However, McCoy later admitted in the game's ending that Campbell was not actually involved in the process, and that they "weren't old friends."

Super Smash Bros. Brawl
Colonel Campbell is among one of four Metal Gear characters (the others being Mei Ling, Hal "Otacon" Emmerich, and Snake) who appear in Super Smash Bros. Brawl, and gives Solid Snake advice and detailed background regarding his opponents via Codec (a hidden taunt; one of Snake's many secret scenes).

If Snake's opponent is Luigi, his AI dopplegänger takes his place and bombards Luigi with verbal insults rather than providing Snake with relevant and needed information. To this, a sudden role reversal occurs, in which Snake yells out for Campbell to "snap out of it" in the Game Over fashion. Also, as Snake tries to give credit to Luigi's efforts in the field of battle, Campbell rambles the phrase "La-li-lu-le-lo!" repeatedly.

Campbell also appears in the game's E3 trailer in 2006, contacting Snake's Codec and informing him of an invitation to participate in the upcoming Smash Bros. installment, to which Snake simply replies that he is performing a reconnaissance operation, investigating a battle between Kirby, Link, Pikachu and Mario through his trademark box.

If Snake attempts to get information about Falco, although he ends up having to talk to Slippy Toad because the latter hacked into Snake's Codec, it was implied that he was actually intending to call Campbell.

Metal Gear Solid 4: Guns of the Patriots
In Metal Gear Solid 4: Guns of the Patriots, Rosemary tells Snake that Campbell had indeed been Raiden's commanding officer, despite the AI construct's impersonation in Metal Gear Solid 2, suggesting that Campbell briefly rejoined the military for a period of time.

Campbell has green eyes in his official Metal Gear Solid artwork, and his younger appearance in Portable Ops. However, in Metal Gear Solid 4, he has blue eyes, as shown during Act 1 when he and Otacon meet Snake aboard the helicopter.

The Metal Gear Solid 4 Database erroneously states that the CIA had pressured him to command the operation in Shadow Moses in exchange for Meryl's life. It was actually the Pentagon and Richard Ames.

Metal Gear Solid V: Ground Zeroes
Campbell is referenced in the Déjà Vu Extra Op from Metal Gear Solid V: Ground Zeroes, his dialogue from Metal Gear Solid imitated and paraphrased by Miller during the end quiz segment.

Versus Battle
Campbell appears in the Versus Battle on the series official website.

Retirement
In the Japanese versions, Takeshi Aono voiced Campbell in most of his appearances while Toshio Furukawa voiced Campbell in Portable Ops. Aono and Furukawa previously worked together for two versions of the same character in the Dragon Ball anime, where the former voiced King Piccolo and the latter voiced his son/reincarnation, Piccolo Jr. Hideo Kojima tweeted that Campbell will not be present in any future Metal Gear games out of respect for the late Aono.
