Kagura has gotten fat because of her recent degenerate lifestyle. She goes to Otae for advice, but Otae has also gotten fat from eating too much ice cream. Satchan laughs at the both of them for becoming fat, but she has also gotten fat… The three spurred to do something about their situation. They join a famous fasting dojo in town. There they run into Otose, Catherine, and even Kyubei…

helado antes de cada comida.
Basta comer sorvete antes 
de todas as refeições.
