Koichi Haimawari

Koichi Haimawari (灰廻 航一), also known as The Crawler, previously Nice Guy, is a vigilante hero. He is the main protagonist of Vigilante - My Hero Academia: Illegals.

Appearance
Koichi is a skinny man with short brown hair.

His costume consists of his normal clothes in conjunction with an All Might-haired hooded jacket, a black mask covering his face, red sunglasses, and bike protectors.

Personality
Koichi has a simple personality and rather shy, he sees no problem in using his Quirk in public even though he is not a pro hero. That is what brings him to start doing good deeds for the public such, as returning dropped items, giving directions, helping people get onto trains, being a cameraman, and recycling. He has a very heroic nature and cannot ignore people that need help.

He tends to be a rather calm person, reacting to many situations in an appropriate manner. He is reasonable and is open to discussion with thugs and petty criminals, as seen with his interactions with the Three Storm and Stress Brothers. At the same time, he is quick to help when there is a real need for his abilities against Villains, showing that he can be attentive as well as calm.

He dreams of being able to become a recognized hero and is shown to enjoy the vigilante work that he does. He is willing to do the less glamorous jobs, such as cleaning up trash and does not seem to think that these are negative aspects of being a hero or vigilante. He refuses to give up doing it for the reason that it seems uncool because he claims that that's not the sort of person he is, showing that he does not seem to want to be a Hero for fame or money, but out of a genuine desire to help society and other people.

History
When he was younger, Koichi was determined to be a hero, but the morning of the high school entrance exam, he stopped to save a drowning child. He gave the child his silver age All Might hoodie to keep warm, and then rushed off to the exam, for which he was too late.

Synopsis
Koichi is watching a giant monster terrorizing the city. Suddenly, All Might appears and defeats the monster with ease. The public is awed at All Might's strength. Seeing that everyone is unharmed, All Might takes his leave. Koichi is inspired by heroes like All Might and wishes to be one like him in the future. Late for his job he uses Slide and Glide to move faster. However, a Police officer stops and berates him for using his Quirk. After the police officer leaves, Koichi runs towards his next destination and is annoyed that he must follow the rule of unable to use Quirks in public. Koichi runs into a group of thugs and knocks into Soga Kugizaki, which spills the juice he just brought. The thug orders Koichi to apologize by getting down and groveling. Soga prepares to step on Koichi, but the boy slides backwards, which surprises Soga. Koichi slides away and escapes from the thugs.

Koichi sees another group praising a freelance idol, Pop☆Step. Koichi notes that she is taking a big risk in being a freelance idol since she does not have a permit. Despite her songs not being great, the aspect that stands out is her ability to fly which is what attracts some people to become her fans. A police vehicle is passing by, so Koichi warns Pop☆Step. As she ends her live performance, Koichi slides to his place of work. Koichi works at a convenience store; the manager is not pleased with Koichi being late and deducts his pay. Customers arrive, however, it is the same group of thugs that Koichi encountered earlier on. Soga becomes angry at seeing Koichi again and takes him outside. Soga beats Koichi up; Koichi is unable to fight back because Soga threatens him with spikes. After being forced to buy juice for Soga, Koichi is annoyed at being beaten up and changes into his "suit", an All Might-styled jacket with a hood and wears a mouth mask. Koichi decides to deliver justice on his own accord without being bogged down by the law.

Koichi starts doing good deeds for the public such as returning dropped items, giving directions, helping people get onto trains, being a cameraman, and recycling. The citizens thank Koichi and refer to him as Nice Guy. Koichi feels overjoyed in helping people as it relieves him of stress and makes him feel warm inside. With his good deeds done for the day, Koichi begins walking home. Suddenly, Pop☆Step hands Koichi juice to drink. She thanks him for warning her about the Police and followed him in order to properly thank him, but mocks Koichi for being weak, to which Kouichi defends himself as being poor at dealing with violence.

Pop☆Step finds it ironic that Koichi is wearing an All Might hoodie but is bad at fighting. Koichi wears the All Might hoodie because it symbolizes his ideal in being useful in his own way. After they scrutinize each other for their objectives, Pop☆Step begins leaving but bumps into Soga. The thugs recognize her as the online idol and begin mocking her. Koichi tries to stop them, but the thugs ignore him. Koichi sees tears in Pop☆Step's eyes and cannot ignore her plea for help. Koichi theoretically wonders how he can handle the situation; use his Quirk to trip two of the thugs and take out Soga by tackling him so that Pop☆Step can fly away.

Koichi decides to put his plan into motion but fails to knock over Moyuru Tochi, who picks up and throws Koichi to the ground. The thugs turn their attention to Koichi and Soga scratches Koichi's face with spikes from his foot. Soga decides to finish off Koichi for annoying him and then to strip down Pop☆Step.

As Soga prepares to strike, Knuckleduster interrupts, crashing down onto a trash heap. Suddenly, the old man punches Soga, knocking him down to the ground and surprising Koichi. The other two thugs are shocked at what transpired and ask for the old man's motivations. He tells them that he specializes in dealing with hoodlums. Knuckleduster defeats the two thugs and checks their tongues as he is looking for a signs of Trigger. Knuckleduster turns his attention to Koichi and praises him for his efforts, telling him that he can become a real Hero if he works with him. Koichi shows no interest, but Knuckleduster can see through his lies and knows he is someone who cannot abandon people in need, like All Might. Koichi admits that his Quirk is not useful and could never pass the Pro Hero Exam. Knuckleduster does not care about whether Koichi has a powerful Quirk or license because they have absolutely nothing to do with justice. Knuckleduster believes that true Heroes take action when something rises up before them. Koichi realizes that Knuckleduster is unlicensed.

Suddenly, Soga takes Pop☆Step hostage, threatening to claw her face off. Unable to let him get away with his atrocious act, Koichi charges at the thug and knocks him down, allowing Pop☆Step to fly above for safety. Knuckleduster punches Soga into the wall, which knocks him out. Knuckleduster sees that Soga is not in possession of Trigger and makes a copy of his ID. Knuckleduster informs Koichi that there are more ways to be a Hero than what the world says; Knuckleduster is a hero because punishing evildoers is refreshing. However, Koichi finds Knuckleduster to be dangerous and turns down his offer.

Koichi then returns to his apartment, only to find Knuckleduster their.

Quirk and Abilities
Slide and Glide: Koichi's Quirk allows him to slide on the ground, but to do that he needs to touch the ground in at least three places. Koichi has also displayed the ability to slide up vertical surfaces. In Chapter 18 it was discovered he doesn't need to touch the ground in order to propel himself and is capable of limited flight.

Enhanced Speed: Slide and Glide grants Koichi enhanced speed, allowing him to move as fast as a bike. He is able to go faster but at risk of losing control and hurting himself.

Maneuverability: After being coached by Tensei Iida, Koichi learned to maneuver well by accelerating in opposite directions. He now possesses the abilities to move and perform tight turns at high speeds as well as brake.
