History#
At some point, Tensei became an independent pro hero at a young age. During a meal, his father congratulated him for this and for having numerous sidekicks who follow him. Tensei thanked him for the compliment but corrected him by saying that it is actually the other way around, since he has no talent or anything and depends on his sidekicks to live up to the name of hero, glad that they help him to save people.[1]
His heroic yet humble demeanor makes his younger brother Tenya look up to him, aspiring to be a hero like him. One day, a young Tenya asked him what motivated him to be a Hero, to which Tensei half jokingly replied that to to flirt with girls. More seriously, he replied that both their parents and grandfather were heroes, and therefore it was expected to him become a hero too, but in true he becomes one because he wanted to be a 'cool' type of Hero that helps others when they are in need. When Tenya spoke of his admiration for his older brother, Tensei was joyful that Tenya looks up to him and said that he must be a great Hero since Tenya admires him.[2]
My Hero Academia: Vigilantes#
Vigilantes Beginnings Arc#
Tensei is patrolling Naruhata when he receives a backup call due to an inexplicable and sudden appearance of several Instant Villains in the city. Tensei runs to the place where the villain outbreak is taking place and together with other heroes who had also received the call, they subdue all the Instant Villains in a short space of time.[3]
Sometime later, Tensei attends a meeting at the police station with several of the heroes who had participated in suppressing the outbreak. Once in the meeting room, Detective Eizo Tanuma informs them that the Instant Villains they had defeated are unwilling civilians who were injected with Trigger by someone. The officer explains that the people in question were more victims than they were villains.
When the meeting ends, and Tensei prepares to return to his duties, the police station is attacked by the Suicide Bomber. Tensei and other heroes prepare to face him, but the villain is quickly defeated by Midnight and Eraser Head. After congratulating them for their work, Tensei leaves.[4]
Some days later, Tensei and his hero agency Team Idaten are dispatched to the Naruhata district highway for reports of a runner-type villain whose Quirk is amplified by Trigger. This time, Team Idaten's PITO1 truck is chasing the running villain, and after having confirmed that there are no civilian vehicles ahead, PITO1 allows Turbo Hero "Ingenium" to chase down the running villain.
While Tensei is initially able to catch up to the villain, he fails to match with the villain's greater range of mobility, for which the villain mockingly states that the Turbo Hero must stake his life on running if he wants to catch him. The villain effortlessly avoids Tensei's attempt to subdue him and kicks him, causing Tensei to crash due to his high speed. An airbag system prevents the crash from being fatal. The villain manages to escape and disappears.
Determined to catch him next time they meet, Tense decides to jog through the streets of that part of the city to study the terrain well. During a morning jog, he meets with Koichi Haimawari who was using his Slide and Glide Quirk without permission. Tensei catches up to Koichi, which shocks him, and manages to stop Koichi from crashing.
Tensei introduces himself to Koichi as the Turbo Hero: Ingenium. Koichi is fully aware of the law preventing the use of Quirks in daily life and decides to practice early in the morning to avoid authorities, so he fears Tensei arrest him for illegally using his Quirk. Instead of arresting Koichi, Tensei takes an interest in his mobility-type Quirk and even offers him advice, apparently solving one of Koichi's biggest faults when using his Quirk. Impressed by Koichi and his Quirk, Tensei happily offers him a business card to Team Idaten, assuring him that even an unlicensed hero such as Koichi could find a place on his team, and in time obtain his hero license.
Later, Tensei and Team Idaten are again tasked with capturing the runner-type villain, who notes that Tensei seems to be making sharper movements. Tensei made the decision earlier to sacrifice all the safety measures of his suit (much to his team's disapproval), in order to shed as much weight as possible and match the villain in his mobility. The villain believes he has successfully convinced Tensei to foolishly risk his life to keep up with him, but Tensei makes clear that he did not merely endanger himself to keep pace; instead, he is trusting that his team will keep him safe.
Tensei and his team devise a strategy in which Tensei would lure the villain into a dead-end strip of the highway, with the rest of Team Idaten ready to apprehend the villain when he falls into their trap. While Tensei is kept safe thanks to the crash pads his team laid out for him, the villain avoids the trap entirely when he reveals he has bat wings and the ability of flight. The Bat Villain then escapes from the highway and takes to an old part of the Higashi-Naruhata district, all while avoiding Team Idaten's coordinated attempts to corner and subdue him. Tensei remarks the difficulty of the operation is due to the town's unfamiliar layout and the villain's ability to use the shadows to his advantage.
Later in the chase, Tensei and his team unexpectedly find the villain beaten and subdued, all thanks to the efforts of the vigilantes Knuckleduster and The Crawler. The Crawler claims that being used to the old district's layout makes it easy to determine the villain's likely escape route. Seeing that their job is done, the Vigilantes retreat. A Hero of Team Idaten asks Tensei if they should chase after them. However, Tensei decides to call it a night.
The next morning, Tensei meets with Koichi again during his morning jog in order to thank him, having recognized him from the night before. Though Koichi is terrified of having his identity revealed, Tensei says that the vigilante's secret identity is safe with him. Tensei then requests the return of his business card, claiming that Koichi has already found his place as "The Crawler", and he respects him for it. Much to Koichi's dissatisfaction, he returns the card, to which Tensei makes the attempt to cheer up his jogging buddy with a friendly race.[5]
Senpai Arc#
While in Tokyo, Tensei and his team receive a request for help: a cat with a Quirk had taken control of a bus full of tourists and was now roaming the streets without control, so it was feared that the situation would end in a disastrous accident. Tensei decides to go ahead to help the tourists.
Everyone in the bus is panicking until Ingenium comes to the rescue as he enters the bus, finding that Koichi is also one of the passengers, with his mother Shoko and his friend Makoto. They both decide to pretend they don't know each other. The driver informs him he cannot use the brake or steer the vehicle, to which the Pro Hero notices it would be difficult to stop something so big, and fears for the possibility that the bus may have crash in a urban area.
Suddenly, Knuckleduster appears in front of the vehicle, holding a large handmade cat toy to get the attention of the cat bus, and tosses it aside to make the bus divert into an express lane, and thus prevent it from crashing. Still, now they are heading to a destroyed overpass and they only have a few minutes time-limit to the hero. Team Idaten comes on its way with a truck, including their new recruit, Enigma, who uses her Quirk to transfer passengers from the uncontrolled bus to the truck. Koichi’s group are the last three people to be rescued.
Unfortunately, Kuin Hachisuka, the villain responsible for the whole situation, has been watching the events, and she is not willing to make things easy for Tensei and his team, so she gives the cat a dose of Trigger, causing it to attack the truck and move away, with Makoto still on board. Right as Ingenium goes after the bus to rescue her, he starts to run out of gas. He informs his crew about this but they can’t help because the truck is out of commission as they ask for a request of someone with a mobile Quirk. Koichi decided to help under his alias as The Crawler, giving him grapefruit juice to fill his fuel.[6]
The two collaborate together to catch up the bus as they try to dodge its tail. At one point, Tensei has to use a Recipro Burst to kick the Cat Bus when it is about to hurt Koichi, but in doing so, he is forced to cool down to prevent his engines from overheating. Koichi enters the bus and rescues Makoto, jumping off the vehicle as it begins to free fall from the the broken overpass.
Ingenium uses his Ultimate Move, Rocket Charge, and tries to catch him, but its not enough. Koichi makes up with his force of will, allowing him to jump in midair. Thanks to this, Ingenium has a hold of Makoto as both Quirk users are able to land on the other side of the expressway, with Koichi tumbling. The bus ends up crashing, but luckily no one is hurt.[7]
Vs. Queen Bee Arc#
Several days after the incident with the Monster Cat, the Marukane Department Store decides to hold a festival about the Naruhata neighborhood to celebrate its reopening. In addition to local artists, they wanted appearances from hero involved in the recent outbreaks of villains.
Tensei is one of the heroes invited to participate, however due to scheduling problems (getting his gearshift modified), he is unable to attend, being one of the few to decline the invitation.[8]
Osaka Incident Arc#
Tensei is filming an commercial together with Captain Celebrity. After finish the shooting, Captain notices himself looking less than stunning in one frame and asks for a reshoot. His manager Makoto apologizes to Tensei for having to shoot it all over again, but he doesn't care and obliges. The Captain is glad, saying Ingenium has the attitude of a Pro-Hero.
However, among the members of the film crew is villain Number 6, disguised as one of the crew members. Using a device, he remotely controls a truck inside which is the Bat Villain, now transformed into Next-Level Villain. As the reshoot is about to begin, the truck crashes in and releases the Bat Villain onto the scene.
Bat Villain chases after Tensei who recognizes him. The Bat Villain glides over Tensei who tries to hold onto him and keep him grounded, however, the Bat Villain was anticipating this and kicks Tensei, causing him to fall to the ground. The Villain goes flying from the place to look for the Naruhata Vigilantes, because he also wants to take revenge on them for defeating him last time. Thanks to the Engine Quirk from his elbows, Tensei manages to cushion the fall and does not sustain any serious, and asks Captain Celebrity to chase the villain.
Captain Celebrity pursues Bat Villain and manages to defeat him when he finds Koichi and tries to get revenge on him.[9]
Sky Egg Arc#
Months later, on the occasion of the return of Captain Celebrity to the USA, Makoto decides to organize a farewell show at the Tokyo Sky Egg, inviting several of Japan's most famous heroes to the event. Tensei accepts the invitation and decides to take the entire Idaten team with him.[10][11] Along with his sidekicks Enigma and Bigshot, Tensei performs some stunts to entertain the audience during his turn.
In the middle of the event, the Tokyo Sky Egg is attacked by creatures known as Bombers, commanded by the villain Number 6. The main objective of Number 6 is to kill Captain Celebrity, and to achieve it he orders the bombers to damage the structure, leaving the Captain celebrity at his mercy by having to use his strength to prevent the building from collapsing, completely defenseless to the Bombers attack.[12]
In one of the rooms of the Sky Egg, Tensei along with several of the heroes who were participating in the event and show staff discuss the situation. They deduce that everything that happened follows a meticulous plan by someone that want to seal them all inside the building. Based on these conjectures, the heroes decide to organize in two groups: one group goes outside and confronts the enemies, while another group helps the show staff to look after the spectators.[13]
The heroes manage to defeat one of the Bombers, which is responsible for having cut off all communications with the outside world. Nevertheless, the cells and the landlines in the facility continue being in-operative. At that moment, Tensei notifies them that the Team Idaten Comm Link have just arrived, which allows communication with the Idaten’s control room. Tensei orders his sidekicks to deploy and assist the heroes on all fronts. Tensei leaves Gang Orca and Makoto to coordinate from inside, while he goes out to provide assistance against the Bombers.
Once outside, He ask Edgeshot about their sitch, and the Ninja Hero replies that they will prevail against those foes. Tensei also reports Best Jeanist that his request has arrived: a truck transporting carbon fiber cables made for suspension bridges. Best Jeanist descends to the ground and uses his Quirk to manipulate the cables and secure the structure, preventing the Tokyo Sky Egg dome from falling.
It seems that everything is over, but due to fatigue and injuries Captain Celebrity can not continue flying and fall from several hundred meters. Koichi, who had been protecting the American hero, unconsciously jumps to save Captain Celebrity. Tensei is not only surprised to see him there, but is also stunned to see him do that madness.
As if that were not enough, Number 6 decides to take revenge on the heroes for ruining his plan and orders the last bomber to self-destruct in a powerful explosion, causing the building to collapse.[14] Fortunately, All Might arrives in time and manages save everybody life.[15] After the tragedy was prevented, Tensei remains to help and organize the provision of assistance and first aid to the victims of the villain's attack.[16]
Naruhata Lockdown Arc#
Tensei and Team Idaten are contacted by Detective Tsukauchi to help apprehend Koichi Haimawari a.k.a. the High-Speed Villain, "The Crawler." After receiving a signal from the detective, Ingenium deploys to catch the vigilante.[17] Tensei catches up to Koichi, telling him that he wants to talk. Koichi attaches himself onto the side of a truck and listens to Tensei, who understands that he is in danger and that they want to do whatever they can to help him and the comatose Kazuho Haneyama. Koichi replies that he will go to the police when Kazuho's safety is ensured, and apologizes as he blasts away. Koichi sees a trap set up by Tensei and his team, but escapes by flying away. Tensei notes Koichi's improved versatility, and leaves the job to the other heroes that were deployed.[18]
As night approaches, Number 6 shuts down power all throughout Naruhata.[19] As he is passing by the traffic, Tensei deduces that it can't be a coincidence that the power and communications are down at the same time. Tensei, Best Jeanist, and Edgeshot soon make it to Koichi and Eraser Head's location, and reassure the public.[20] At Naruhata Station, the Heroes gather intel on how dire the situation is, learning that the blackout extends for kilometers and the roads and railways are suspended. They notice the similarities to the Sky Egg incident, and prioritize making contact outside Naruhata, with Tensei volunteering to get in touch with his agency.
Koichi walks in and thanks the heroes for their help before attempting an escape, but is restrained by Eraser Head, effectively putting him under arrest. The heroes ask why he didn't leave when he had the chance, to which Koichi says that he wanted to thank the heroes. Tensei lets out a chuckle at Koichi's gratitude and altruism. While running towards his agency, Tensei notices a civilian yelling for help and goes to them. However the "civilian" was actually one of Number 6's Anonymous, and self-destructed, catching Tensei in an explosion.[21]
