One Piece · Wano Country Arc (Act 2)

In Udon prison, Luffy survives Queen's punishments and learns from old Hyogoro to push Armament Haki inside an opponent. He takes over the prison and gains hundreds of allies. Big Mom lands in Wano with no memory, and later she and Kaido seal an alliance. Komurasaki turns out to be Hiyori, Momonosuke's sister, and hands Zoro the legendary sword Enma. Law takes on Hawkins and learns Apoo betrayed Kid. The rebels gather weapons and fighters for the night of the Fire Festival. Two news episodes close the act: the end of the Warlord system and Sengoku telling the story of the Rocks Pirates.
