On the annual school festival, Sorges sends Sushi, an evil sushi chef, to destroy Chacha. Riiya's giant grandfather shows up and offers to make sushi for everyone, with Riiya telling everyone what a good sushi chef he is. However, he is out of everything except egg. Marin summons all kinds of seafood and Riiya's grandfather makes a lot of giant sushi for everyone and Marin goes back to her class. In the hallway, she is attacked by Sushi and made into a giant makizushi. Chacha finds her and Sushi is about to attack her but Seravy arrives and offers to make sushi for everyone. It turns out that Seravy is an excellent sushi chef and everyone loves his sushi. Sushi asks Seravy to teach him his techniques. After some discussion, Seravy decides to teach him, and puts him through a lot of seemingly pointless exercises. After he masters Seravy's sushi technique, he attacks Chacha and her friends but loses after being tricked by Seravy into letting them go. The Daimaō is not happy with Sorges. (Source: Wikipedia)
