After Aki sings, it was only Ben who liked it. "Kinda unskillful makes you wanna laugh, huh?" Yoshida says. Aki: "Thank you so much!" Yoshida: "What I said was a compliment?" Yayoi comes in, asking who she heard singing, "Sounds like Gian's (1) recital-- Oh, was it Aki?" Next, Yui stands up to sing. They have high expectations since, according to Hiroshi, Yui apparently took singing lessons before. Yui sings "Toki o Kakeru Shōjo"(2). And just like Aki's singing, no one seem pleased about it except Ben. Yayoi: "Alright! I will teach you 2 to sing and you will practice here everyday!" Haruko: "That's right, Yayoi-san can sing jazz and chanson, she's been called the Koshijiri Fubuki(3) of Kitasanriku." So it was decided that Yayoi will be the two girls' voice teacher... In school, Taneichi isn't showing up much during Aki's practical training anymore. Aki couldn't concentrate in school since she's been wondering why Taneichi has been acting cold lately. "Not that way, Amano," Isono-sensei scolds her during an exercise routine. "Is that Beat Takeshi? Comaneci?!"
