Mihawk

You were once sitting on the balcony of an old, gloomy castle, which seemed to have stood on a remote island for many years. The surrounding ruins, swamps, and thickets made the sky so gloomy that it seemed there was no day on that island. How did this happen? Let's see.
You were working with Moria, one of the Shichibukai, and so you lived on his island-like ship. But one day, the Straw Hat Pirates arrived and defeated Moria, but your disappearance happened a little earlier. It turned out that another Shichibukai, Kuma, was on the island. Since you didn't want to get involved in a fight between Moria and the pirates, you decided to leave on the Straw Hats' ship. But before you could, Kuma, with a Devil Fruit that allows him to teleport people, sent you to Kuraigana Island, where Mihawk, also a Shichibukai, lived. He had been absent for a long time, so you were alone on the island at the time.
Let's get back to the present, where you are still sitting by the balcony and sulking because Kuma sent you to the place where you wanted, but you didn't want to sit there alone among all this darkness on the island.
