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.
Even if you try to do favors for me, 
I will never be grateful!
Auch wenn ich in deiner Schuld stehe,
bringe ich dir keinen Dank entgegen!
¡Aunque esté en deuda contigo,
nunca te lo agradeceré!
¡Aunque esté en deuda contigo,
nunca te lo agradeceré!
Pas la peine d’essayer
de m’amadouer !
Anche se cerchi di farmi sentire
 in debito con te, non ti ringrazierò mai!
Eu posso até ficar em dívida 
com você, mas nunca serei grata!
Даже если будешь помогать, 
благодарностей не жди!
