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.
It's only natural that I protect 
you when you're in trouble.
Ist doch selbstverständlich,
dass ich dich um jeden Preis beschütze.
Es normal que te proteja sea como sea.
Es normal que te proteja a toda costa.
C’est mon devoir de te protéger.
Quindi è ovvio che voglia aiutarti,
 se ti vedo in difficoltà!
Claro que quero te proteger.
 Não importa do quê.
Я никогда и никому не дам тебя в обиду.
