Mika cheerfully greets vampire noble, Ferid

Seventh Progenitor Ferid Bathory arrives at that point, and the vampire returns Yu to the walkway before taking his leave.

When he asks if both Mika and Yu will be joining him tonight, Mika accepts but also prevents Yu from causing another scene with the reason that Yu cannot join them, he is too shy.

Later on, Yu asks Mika if he knows that vampire, and Mika answers that he gives Ferid blood in exchange for good food and anything he might need. Hearing this, Yu punches him lightly in the head and leaves.

That night, Mika returns quietly into their house, Yu hears his creaking on the floorboards. They chat briefly, Yu says he will give his blood next time but Mika insists that no one wants his nasty blood. Mika breaks into tears for a moment when he tells Yu that Yu gives them hope.
