A Desperate Situation! Orochi's Menacing Oniwabanshu!

Robin is attacked by the Oniwabanshu ninjas. She uses the clone technique to save herself just in time. She returns to the banquet to hide in plain sight among the other geishas. She approaches Orochi and gets herself invited to the party on Onigashima on the night of the Fire Festival. Meanwhile in Kuri, Chopper and O-Tama practice their ninja skills, and Momonosuke practices his sword fighting techniques. They notice a big figure on the beach. Much to Chopper’s horror, it is an unconscious Big Mom, but when she wakes up, she has no memory of her past.
