Hosu City

Hosu is a ward located in My Hero Academia's version of Tokyo, Japan.

It's the main setting of the Field Training Arc.

Description
Hosu is a city district located to the west of Tokyo. Aside from a hospital, the ward doesn't have other known landmarks yet. Part of the district was also attacked by Artificial Humans.

The Pro Hero Ingenium was known to act in this district, but an attack caused by a mysterious figure left him paralytic, ending his career. Other notable Heroes known to act in this district include Manual and Endeavor.

History
During a mission in Hosu, Pro Hero Ingenium was attacked and struck down by the mysterious Hero Killer Stain. Tenya Iida was warned about this midway through the Sports Festival and abandoned the competition to meet his now crippled brother in the Hosu General Hospital.

Later, after having to choose a workplace to spend a week as an intern, Tenya went here to train with Mizushima Masaki, with the intention of seeking revenge.

As Tomura Shigaraki unleashed his Artificial Humans in the district, Izuku and Gran Torino were passing through it by bullet train, until they got attacked themselves. In parallel, Endeavor and Shoto Todoroki were acting in Hosu to stop the Artificial Humans, as well as to confront and capture Stain.

Tenya was able to find Stain as he acted to kill a nearby hero in an alley. Tenya was no match though, but Izuku and later Shoto came to his rescue, with the trio managing to defeat and capture the Hero Killer. After the incident, Izuku, Tenya and Shoto recovered from their injuries in the Hosu General Hospital.
