Remember an idea + don't get your hopes up: Yuzuki Pu traveled to the world of Bungou Stray Dogs at the moment when he was about to die, and was picked up and cured by Ogai Mori. He became a person with super powers. He has the superpower called "Earth-bound Boy Hanako-kun". When the superpower is used, he will become the seventh of the seven incredible incarnations of the undead.
Intention: What if Yuzuki Pu did not die but traveled to the world of Wenye and became a person with super powers?
