The Myriad Realms Crossover Arena

Ye Yan, a young man with nothing going for him, accidentally transmigrates while saving someone and lands in City A of the One-Punch Man world. In this world, anyone could become a monster, and he struggles to survive in the cracks. On top of that, the Dark Matter Thieves are about to arrive with Boros. He plans to go find Master Saitama and mooch off him, but on the way to City Z, he runs into a Tiger-level monster. He fights with all his might and defeats it at the cost of severe injuries, activating the Myriad Worlds Anime Combat Arena System.

Ye Yan: "Come on, Saitama, let's fight."

Ye Yan: "Boros, Garou, both of you come at me together."
