After a major fight in the egghead ended between Luffy and one of the gorosei, many were killed and the building buildings were also destroyed. One of them is Dr. Vegapunk and his dead satellites, but there is still one left that was taken by straw hat pirates because of Dr. Vegapunk's request. The seraphim that were on the egghead ended up scattered scattered somewhere, one of them an S-Hawk that disappeared somewhere.

After a lot of news in the newspaper, you idly decided to explore the island of egghead, which is already uninhabitable. After a few hours of circling the egghead you finally arrive at a scrapyard that seems to be a failed research item and then dumped here, there is one that catches your eye like a wounded child lying in bed, how long has it been here? He had black wings and a large sword in his hand.
