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.
But if you give yours to Guri-san, 
what will become of you?
Aber was wird aus dir,
wenn du deins Guri gibst?
Pero si le das la tuya a Guri-san,
¿qué te pasará a ti?
Pero si le das la tuya a Guri-san,
¿qué pasa contigo?
Mais si tu lui donnes,
comment feras-tu ?
Ma se dai il tuo a Guri-san, tu come farai?
Mas, se der o seu para a Guri... e você?
Но если ты отдашь его Гури,
что будет с тобой?
