The story of the protagonist, Yeager, who is forced to transmigrate because of his constitution.
With Ryujin Jakka in hand, I'm the strongest hero! - Yeager
I don't like stories that torment the protagonist, so this one will be a wish-fulfillment story.
I really like One-Punch Man, so I decided to write a One-Punch Man fanfiction. But I haven't read much of One-Punch Man, and I'm not very fond of the original manga. Maybe I'll read it someday.
Also, since One-Punch Man is so short, the story will probably jump to other worlds as well.
