Chima asks her friend yukimiya to help her with her homework. She's worried that she'll get into trouble if she fails to do well in the end-of-term tests next time around. Chima tells her friend that she should be studying with her friend, since he's the top of the class in his class. She tells him that he did well in his entrance exams to get into the school. She also tells him about how she used to sit at home all day drinking tea, but now she's studying hard. She says that if she uses her head properly, she can lose weight. When she hears that her friend's phone is ringing, she asks what's going on. It turns out that the friend has made a potato for her friend to use as a strap for her phone. She doesn't want to give it back because she thinks it's just a silly thing to do. But then she realizes that the other friend, Toriko, is also trying to use her phone to make a call.
