02Appearance
Manabu is a little boy with an average constitution, and a round face. He seems to be the same size as Koichi Mugikari. He's got unkempt dark hair. He notably has freckles in the middle of his face and puffy hair. He also happens to be missing several front teeth.↗
Cool Shock Old B.T.
In the first chapter of Cool Shock Old B.T., set decades after the original series, Manabu has become an old man who is lean and a little smaller than B.T.. He is now bald with several wrinkles. Manabu still wears a trucker jacket but under it wears a shirt with a double circle motif, and a pearl necklace. His pants have an arrow motif imprinted on them, as do his shoes which have black and white arrows imprinted under the soles. Manabu now wears round glasses and walks with the help of a cane, which hides a sword inside.↗
03Personality
Manabu is a devious, greedy and violent boy who revels in exploiting others.↗
When he appears, the freckled boy seems to be innocent and reasonable, although he shows an unusual high level of familiarity. As Koichi's parents try to get on his good side by welcoming him inside of their home, he quickly abuses their hospitality, from sleeping on the couch immediately after going in to devouring a large part of the family's dinner while complaining about the meat being too salty to Koichi's mother. He then steals Koichi's clothes for himself. In general, Manabu has a cheerful and friendly behavior but it is only an act in order to approach his victims.↗
Manabu's unpleasant behavior can be explained by the fact that he comes from a family of hustlers. Manabu cheerfully claims that they routinely infiltrate households, probably using Manabu as bait to catch the victims unaware and frightful of the consequences of having run over a boy. The family then uses the opportunity to force themselves inside of a house, intimidating the victims by playing the victims themselves, overreacting and pretending that the victims are assaulting them. This leaves the victims unable to do anything for fear of the police believing the story of Manabu's family.↗
04Abilities
Intelligence
Manabu is a fairly intelligent and devious boy, coming from a family of hustlers and thus having an affinity with hustling, manipulation and cheating.↗
He demonstrates a good deal of cunning and is the only opponent in the series to beat B.T. in a battle of wits. By preemptively cheating and making B.T. drop his guard to bait him into a bet he was sure to lose. Likewise, Manabu seems to act as bait on a regular basis to help his family take over households through acting and deception, playing the victims so that the real victims feel they can't call the police for help.↗
Equipment
Butterfly knife: Manabu possesses a butterfly knife which he uses once, throwing it at B.T. However, he misses.↗
Sword Cane: In the spin-off Cool Shock Old B.T., Manabu now possesses a sword cane. He charges toward B.T. with it but the sword misses B.T. and punctures his vintage car's tire instead after Manabu is hit by a car.↗
05Story
SPOILERS
Cool Shock B.T.
Not much is known about Manabu before his encounter with B.T., as Koichi comments on the mystery around the boy's age, upbringing, and school. His close family is made up of 6 people total including himself, appearing very close to one another as they assist each other in their deceit.↗↗↗
Manabu is first introduced in the story pretending to be the victim of an accident caused by Koichi's father while pulling out of their driveway. Worried about the boy's "injured" state, they bring him into their home, letting him rest and offering to take him to the hospital to which he declines. Once he's entered and secured the house, Manabu naps for several hours.↗↗
After an undisclosed amount of time between Manabu winning the bet and the group entering the house again, the Mugikari family is met by a sudden ring at the doorbell. Manabu runs to the door to open it and the rest of his close family is revealed as they invade the house as well. When B.T. visits Koichi the next morning, Manabu and his family are still at the home, having stayed the entire night.↗↗
The Gorgeous Train Incident
At an underground subway station in London, Manabu approaches Irene Rapona who is struggling to purchase a ticket, and offers his assistance by buying one for her. Manabu claims that tourists have to help each other out. After Irene accepts his kindness, Manabu claims that perhaps she wouldn't feel right just taking it for free. Instead, he proposes a gamble to settle the debt.↗
With his victory seemingly assured, Manabu declares his guess is the "lucky seven" of hearts. However, Irene flips her card around, revealing that it is actually the eight of hearts. Shocked and screaming that it's impossible, Manabu snatches the card from her hand, noticing that it has a strange smell. After he sniffs it, he loses his balance, falling backward off the station platform and into the path of an oncoming train.↗
The Smoker Under Arms Incident
In the year 202X, Manabu is a young adult and professional swindler. It is shown in a flashback that he collaborates with other gamblers to cheat casinos out of their money and he advises one of his gamblers, Mike Harper, not to try cheating at the Dinosaur Hotel, because B.T. is working there. Nonetheless, Mike thinks Manabu is being overdramatic with B.T. and still goes to try to cheat at the roulette.↗
The Eerie Freckled Old Geezer Incident
At some point, Manabu becomes the boss of an organization called "The Outlaw Guys". Disguising themselves as an investment company, The Outlaw Guys scams the elderly to steal their property and income. Manabu hires young adults to work for him, referring to them as his slaves. One day he blackmails an elderly lady from a candy store by mentioning that her reputable grandson may have knocked up a teenage girl, so she runs around collecting money for him so he doesn't spread the rumor.↗
While the two take a long time before coming back to Manabu's hideout, Manabu reads a novel that Koichi wrote when he was younger called Cool Shock B.T. He suddenly realizes that the video must have been a ploy and declares to his gang that they have two minutes before they must evacuate the place. Before they could all leave, B.T. crashes into the building with his car. The boss declares that he knew they would try to hit him with a car again, since B.T. did with an ambulance 60 years ago.↗
The Say Hi to Old Virginia Incident
In the year 2060, B.T. and Koichi Mugikari board a spaceship and travel into space.↗
When B.T. and Koichi fly into space, Manabu follows them aboard his own private spaceship. He then contacts Koichi while hiding his identity and reveals the existence of the bombs. Waiting a moment before parking next to B.T.'s ship, Manabu recontacts the ship just to enjoy the despair of his foe. Gloating, Manabu wants to warp into the ship to become B.T.'s master once he yields. However, B.T. has already disarmed both bombs. Plus, B.T.↗↗
