Guri finally meets Seiji's younger sister, Akua and is surprised by her rather cold attitude towards her big brother. The cupid decides to learn more about what changed this once loving sister, and Yuzu is right there to help (or make things worse...). But while the girls are getting acquainted the demon Stolas appears and a panick ensues! The strangely psychotic penguin seems to have a special affinity for Akua and sends her running. It's up to her big brother Seiji to save her like he used to.
You were all content just to 
be dating me, weren't you?
Ihr wart doch all die Zeit zufrieden,
die ihr mit mir verbracht habt.
Eran felices de salir conmigo, ¿no?
Os gustaba salir conmigo, ¿no?
Vous étiez bien contentes
de sortir avec moi, non ?
Eravate soddisfatte perché uscivate con me, no?
Vocês estavam satisfeitas de
 sair comigo, não estavam?
Никто ведь из вас не был против 
несерьёзных отношений.
