[Various Series/One Piece] A Vacation Diary in Another World

!!! Attention!!!

This story has been changed to an OC plus time travel story.

After hundreds of Holy Grail Wars,

this one has descended upon the world of One Piece.

Unlike before,

the Heroic Spirits this time come from all sorts of worlds,

and every one of them is someone burdened by an obsession.

So who will claim victory this time?
