Aina Aoi is a rising student of Class 1A at UA High. She's determined to make it to the top, and isn't interested in making friends. Then she meets cold and silent Shoto Todoroki, who seems to be the only likeminded person in this school. Both with their guards up, and neither loooking for companionship, the meeting of these two heroes in training is something that is bound to save the world, and perhaps change their lives for the better.
