Story
Shirase takes the party to the beach. Mamako tries to be close to Masato, but he refuses to play. Shirase suggests watermelon splitting. However, when Mamako's instructions cause Masato to walk into her breasts, he throws his wooden sword into the sea, only for it to come back and hit him in the head, causing amnesia. His vague memories of Mamako cause him to start being nice to her. Suspecting Masato may quit their current adventure, Wise and Medhi try to seduce him in order to hit him on the head again, but he refuses their advances. Masato then meets up with Mamako. While they are alone, he declares his love and tries to kiss her, but suddenly she is grabbed by a giant kraken, causing him to suddenly cry out "Mom". After Masato saves Mamako, the kraken grabs him instead. Mamako defeats the kraken and uses her Mother Ocean sword to part the ocean. With Masato's memory back, the party decides to barbecue a kraken tentacle, only for it to explode off the grill and hit the girls on the head, putting Shirase in a coffin, but leaving Mamako, Wise, Medhi and Porta with amnesia.
