The day of the battle has finally arrived. The student council president, Kokubyakuin Seira, appears to know something about the Absolute Choice and about Chocolat. Meanwhile, she promices to say that she likes Kanade if Kanade wins against her in battle.
I think "Together with 
Onii-chan" would be good.
Ich denke, "Zusammen mit 
meinem großen Bruder" wäre gut.
¡"Junto con Onii-chan" sería genial!
¡"Con Mi Hermanito" sería genial!
Pourquoi pas
« avec grand frère » ?
Eu acho que "Junto do Onii-chan" é ótimo!
