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.
Besides, no matter how dumb the angel,
Egal wie dämlich ein Engel bisher
jemals war, nie hat einer sein Notizheft
Además, aunque fuera muy tonto,
Además, aunque fuera idiota,
J’ignorais qu’il existait
un ange assez stupide
Nemmeno il più cretino tra gli angeli
Mesmo entre os anjos mais burros,
Я много глупых ангелов повидал, но чтобы
кто-то допустил такое — это впервые!
