Tsumugi wants to throw a party: a gyoza party! And a party means that she can invite all her friends, everyone she knows at daycare, and Kotori, and Shinobu, and even Yagi! But she's just a little girl, and doesn't know that you have to get permission from Kotori's mom before you can hold a party at Kotori's house. How can Kouhei resolve this sticky situation? And what's the best way to make gyoza, anyway?

Tsumugi has decided that she's a cat! When Kouhei gets an ice chest full of yummy fish, she's more than excited to watch him make them! But to make namerou, or as Kotori calls it, "fish hamburg steak" you have to be able to filet the fish, and Kouhei doesn't know how! To make matters worse, neither does anyone else! Can he turn to the internet for help?
