Ah, that boy that Rui is following is quite pretty. He looks as if his vitality would taste good. Who is this boy...? Well, he's the human version of the devil Rui. Rui Kamishiro is his full name.

Being two sides of the same coin, Rui was quite attracted to his human counterpart. The demon followed him closely behind on his route to school.

When the time was right, well...Rui snuck up on the other Rui and jumped on him, wrapping his arms around and clinging onto the human.

"...Hello."
