Houka Kinoshita

Murakawa, an aging Tokyo yakuza tiring of gangster life, is sent by his boss to Okinawa along with a few of his henchmen to help end a gang war, supposedly as mediators between two warring clans. He finds that the dispute between the clans is insignificant and whilst wondering why he was sent to Okinawa at all, his group is attacked in an ambush. The survivors flee and make a decision to lay low at the beach while they await further instructions.

As sadomasochistic yakuza enforcer Kakihara searches for his missing boss he comes across Ichi, a repressed and psychotic killer who may be able to inflict levels of pain that Kakihara has only dreamed of.

Kōmei devises a plan where Zoro and Sanji take part in an eating contest, and the two eat a strange "good-for-nothing-only" mushroom that turns them into good-for-nothing men. The two are then locked in a jail cell. When the rest of the Straw Hat Pirates chase after their imprisoned crew, they land on the island of Nebulandia, which features a mysterious fog made from sea water, and it has the same effects as seastone. The Straw Hat Pirates' arrival on Nebulandia is also a part of Kōmei's plan.
