Adapted from the webtoon of the same name by ONE, the original author of "One Punch Man". Shigeo Kageyama, an ordinary second-year junior high school boy, is nicknamed "Dragon Set" because of his weak sense of existence and the homophony of his name Shigeo, but he is actually a powerful natural superpower. After each growth, Dragon Set began to think that his superpowers were dangerous. In order to prevent his superpowers from getting out of control, Dragon Set unconsciously suppressed his emotions. Although he just wanted to spend every day in an ordinary way, various troubles came to him one after another. As the suppressed emotions expanded in his heart, the power accumulated in Dragon Set was also ready to move. Under the guidance of his spiritual mentor Reigen Shintaka, he tried to coexist with his own power. However, surrounded by his superpowers, he gradually got to know other superpowers, evil spirits, and various organizations, and the people and forces around him were constantly involved in being hurt and redeemed because of his unprecedented power. In the conflict between power and emotion, he gradually learned how to get along with his superpowers, and must begin to consider how to choose to coexist with power and people in a dangerous world in addition to the choice of closing off emotions and abilities.
