K3 Gang

The trio appears in My Hero Academia: Team-Up Missions as a study in ambition outrunning talent. All three dress to a stereotypical punk template, all three ride snowmobiles, and all three treat established criminals as models worth copying, Stain above all.

Their crimes stay firmly at the nuisance end of the scale. They frighten the people living on a mountain and make themselves a problem, but nothing they do causes serious damage, and to their credit they know exactly how weak they are.

Roaming the mountainside, the gang crossed paths with Eijiro Kirishima and cheerfully announced themselves as villains, which held up right until they discovered he was training to be a hero. They ran. Eijiro gave chase, and a snowstorm cut visibility so badly that all three snowmobiles wrecked.

With the storm now threatening to kill everyone present, Eijiro salvaged the blades from the ruined machines, improvised skis, and carried all three down the slope on his back. The rescue landed harder than any lecture could have. Impressed by his spirit, they declared that heroes were their new models, and then they were arrested.

The gang runs three deep under an unnamed leader, and none of the members are identified by name. The group is defined by what it shares rather than by any individual: the snowmobiles, the punk styling, and the admiration for Stain that gave them the idea in the first place.

All of them were taken into custody after the encounter with Eijiro Kirishima.
