The Strongest Hero with One Punch

Have a look

Completed, this is the third work completed by the author. It tells the story of a person with the gift of devouring evolution who gradually becomes the strongest hero through hard work. Saitama did not become One Punch Man in this book, but the protagonist practiced hard to fill the vacancy of Saitama's absence and save the crisis. Highly recommended

Not bad, level 7, (barely)

A fan of Seedling One Punch, the main character cheats by eating various edible weirdos to fully strengthen himself. By the way, the heroine seems to be an older sister.
