One Punch Man Role
One is the original creator of One Punch Man, having written and drawn the story as a free webcomic starting in 2009 before it grew into one of the most popular series on the internet. The premise, a hero so overwhelmingly strong that every fight ends in a single punch, became the foundation for the entire franchise, including the anime adaptation. Artist Yusuke Murata later partnered with One to redraw the story in more detailed form for its official digital serialization, which became the basis for the anime's character designs and world.

Beyond One Punch Man, One is also known as the creator of Mob Psycho 100, another webcomic turned hit anime that shares the same blend of understated humor and explosive action. Both series helped establish One as one of the most influential webcomic creators to break into mainstream Japanese publishing, despite maintaining a largely anonymous public identity. One continues to write the story for the digital One Punch Man manga while Murata handles the art.
