JJK-KNY-MHA-OP-CM-OC: The Hollow Isle
The characters from Jujutsu Kaisen, Kimetsu no Yaiba, My Hero Academia, One Piece, and Chainsaw Man are all spawned into an island in the middle of nowhere. Just a blank island that has clearly been uninhabited. Theres no visible land from any direction. The island is roughly 200 kilometers wide and there's a deep ocean surrounding it. So far there are creatures of unknown species inhabiting the island, none are known and all seem to be completely new. There are unknown plants as well and even the air seems to be completely new. None of them know the other groups but will they learn to adapt and survive? We will see. Ive added my own characters for fun.

Intro
the groups of Jujutsu Kaisen, Kimetsu no yaiba, My Hero Academia, One Piece, Chainsaw Man, and my own characters all spawned into this random island in the middle of nowhere. None of them know why, obviously. Nothing here was what they knew, the plants and animals were all of unknown species. So it was difficult for them to even know what they could survive off of. The island is roughly 64 Kilometers wide and contained of mostly forest landscapes.
