Chapter 14 (Vigilantes)

Koichi Haimawari chases a motorcycle thief while Kazuho Haneyama urges him to hand the matter to the Police Force. Planning to simply keep pace until officers arrive, Koichi eats a Longleg kick to the face and spins out toward a truck, only for a costumed stranger to pluck him from danger and arrest the rider in the same motion. The newcomer commends his nerve while suggesting he leave the dangerous work to professionals, then takes offense when Koichi asks who he is.

He is Captain Celebrity, ranked first among American heroes, and he signs Koichi's All Might hoodie without asking. Told the autograph outclasses the garment, Koichi disagrees, arguing only an owner decides what a thing is worth. Captain Celebrity concedes the point, though he dismisses All Might as muscle without a mind, and departs skyward.

Back in Koichi's apartment, Kazuho and Knuckleduster catch a broadcast announcing the American's move into Tokyo hero work, including footage of him hoisting a cruise liner. Knuckleduster supplies the nickname Captain Catastrophe, along with the tally of lawsuits and scandals that made his home country untenable and drove him to try Japan instead. Koichi is unsurprised, having disliked him on sight, which startles Kazuho, since badmouthing is unlike him. Asked what he is doing, he says he is scrubbing the autograph off his hoodie.

The following day a Godzilla-like villain tears through the city. Watching from the crowd, Kuin Hachisuka judges Gigantification too conspicuous for delicate crime, since heroes arrive within minutes, and files it away as a sample worth taking later. Koichi is guiding civilians out when someone begs for help retrieving Masahiko. Captain Celebrity arrives, hears about the person left behind, and elects to wait, citing the absent media and the lack of any police request obligating him. Disgusted, Koichi goes himself. Word then reaches the American that reporters are en route and dispatch requests are arranged, whereupon he flies in, pounds the monster down and carries a woman to safety.

His carelessness sets the creature thrashing, throwing debris across the district. Koichi weaves through it, reaches the house, and discovers Masahiko is a dog. He unhooks the chain as Captain Celebrity finishes the villain, whose fall topples a building. Slide and Glide gets Koichi and the dog moving, but the collapse gains on them until the American scoops him up to media applause and signs the hoodie a second time. While reporters inflate the rescue, Koichi resents having needed saving, though Kazuho is grateful nobody was badly hurt. A little girl collects her dog with thanks.

Captain Celebrity allows that the dog's rescue belongs entirely to Koichi, if only because animals fall outside his expertise. The compliment is accepted, then undercut by advice to find something less drab than that hoodie, since he would rather not share a camera frame with poor clothing. He flies off, and Koichi still cannot bring himself to like the man.

Captain Celebrity, the top-ranked hero in America, debuts by rescuing Koichi from a fleeing biker and relocates his career to Tokyo.

Knuckleduster reveals the lawsuits and scandals that pushed the American out of his own country.

Captain Celebrity refuses to act against a kaiju villain until the press and police paperwork are in place, leaving Koichi to save Masahiko, who turns out to be a dog.
