Looks like the Psycho-Maniac isn't on your side after all! While he deals with the Thor, he hired an assassin to kill you. His name is Kikuchiyo, an expert swordsman, with his bodyguard Archie. He has sent his men after you. The Psycho-Maniac has set floor 17 to be Kikuchiyo's base. You could just avoid him and his men, but the Psycho-Maniac gave him a crystal to take care of. Get the crystal and defeat him to get to the 18th floor
