One Piece: The Imagination Fruit

Yang Hao, an otaku from the world of anime, transmigrated to the world of One Piece.

After selling fruit for ten years, he finally got his hands on the legendary Devil Fruit he had always dreamed of, even though he was already an old man. And it was an extremely rare Imagination Fruit!

After that, all kinds of unbelievable things began appearing in this world: Soul Reapers' Zanpakuto? Naruto's ninjutsu? Attack on Titan serum?

There's nothing in this world that a wild imagination can't solve. And if there is, then use two.
