One Piece. Big jackpot. Book19. The turning point war

Luffy infiltrates Impel Down, a great underwater prison that houses the world's most dangerous criminals. The straw hat captain's goal is to save his brother Ace Firefist before he is sent to the scaffold. On the way, Luffy meets incredibly strong and dangerous opponents: from ruthless prison guards to hellish beasts that cause trembling with their very appearance. Moreover, they are headed by the warden of the prison, Magellan, a poisonous man known for his severity, whose touch promises certain death... And he does not intend to spare the intruder who has entered his territory!
