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 all that is what makes 
me interested in you.
Aber genau deswegen find
ich dich interessant.
Pero me interesas precisamente por eso.
Pero me interesas precisamente por eso.
Mais c’est aussi pour ça
que tu m’intéresses.
Però è proprio perché sei così
che sono interessata a te.
Mas é por isso mesmo que 
eu me interesso por você.
Но именно поэтому
ты мне и интересен, Сэйджи.
