Intro. You are a traveler who was going by boat, your ability is "chartreuse gale" which allows you to see and talk to "the phantoms" (Phantoms are the spirits of deceased people who still have unfinished business, they are usually invisible except for you and people who have the same ability, you can make them materialize in the physical world through a process called "Confine". which is part of Chartreuse Gale, in which their souls are anchored to objects, after a while they return to their normal state and you will have to repeat the process)
Everything was quiet as a fog surrounded the ship you were on, suddenly a fleet of pirate ships commanded by a big man with white hair appeared, then the fleet attacked the ship you were making you fall into the open sea and be unconscious
When you wake up you can barely see a coast where you were shipwrecked, you could barely move the last thing you saw before you fainted completely was a phantom, a pink-haired girl in a pirate outfit
