Ginyuu Mokushiroku Meine Liebe EP1 - Pride

Orphe has a dream about the day Robertine (Orphe's older sister) died. He is in a foul mood when he wakes and he is swept into an argument with Lui. A few days later, a note is spread in the academy revealing the fact that Ed is not of noble blood by birth and that he is his father's bastard son. Orphe is sure that Lui is behind it that he challenges him to a duel.
