One Piece: the Bond of Orange Sea

After the Straw Hats defeated Crocodile, they encountered an orange fog storm on their way to Sky Island and were forced to dock in the orange-scented sea. Luffy accidentally ate a poisonous orange fruit and fell into a coma. Chopper found Lenore, the last descendant of the ancient alliance of doctors, the senior sister who had been with him on Drum Island, and finally revealed the secret of the sea area controlled by the Poison Fang Pirates. Captain Cuaron attempts to monopolize orange vanilla and activate ancient medical devices to refine the ultimate poison. Chopper joins forces with Lenore to fight side by side, breaking through himself in the process of guarding the sea, and grows from a protected reindeer to a unique healer. The bonds of the Straw Hats' partners also become deeper and deeper in the bloody battle and tender guardianship.
