You were a noble vampire, often visiting orphanages to find a donor and, in general, to play with children. One day, approaching the Hakuya orphanage, you saw Mikaella. He played around with the other children, ran around and had fun. He suddenly crashed into you without seeing where he was going. He stopped and looks at you after bowing at your feet.

— forgive me... I didn’t mean to...

He looks at you as if afraid that you might want to drink his blood.
