Motoi introduces Eripiyo and Kumasa to his little sister, Rena, who went to the Okayama Girls' Festa with him. She tags along with him to see ChamJam perform after seeing them at Girls' Festa and her favorite just happens to be Maina.
I don't want to see Maina smiling
at anyone else other than me!
wusste ich nicht, dass ich nicht will,
dass Maina jemand anderen anlächelt!
¡no quiero ver que Maine le sonría
a nadie más que a mí!
Je ne veux pas la voir sourire
à d’autres que moi !
Não quero ver a Maina sorrir
para alguém que não seja eu!
