Plot
Serizawa had finally awoken his ability and visited the National Talent Research Center. There he got notified that his ability was "Thermal Operator" and it was the lowest class ability, basically labelled as "trash" and is worse than a microwave. That shocked Serizawa, but he still had hopes of improvement. He was then sent to Teihen High School, a F tier school, as no one expected anything from him.

There he met Yomohira Miriya, a goth young looking girl, but that got him intro trouble with Kirisaki Noboru, who loved Yomohira. To his aid, Ueki Hitoshi showed up, but since his ability was also low level, they had to run from Kirisaki. Serizawa then came up with a plan, combining Ueki's and his ability, managing to immobilize Kirisaki and knock him out and formed a new friendship with Ueki.

Ability
Serizawa's ability is called "Thermal Operator", its a "Level 1" ability, capable of changing the temperature of things he touches, making him capable of warming a bath, soup, room temperature or keeping his ice cream cold and not melting but can also heat things up to the point where they become nuclear.

He is capable of making the temperature of things simultaneously extremely hot and extremely cold, allowing him to circumvent the laws of physics and reason by ignoring the normal incompatibility of differing temperatures. He demonstrated this when he heated up a stone to plasma temperature while also keeping it and anything it touches cold enough to cause frostbite upon contact.
