Ep. 2: Staz disrupts Fuyumi's life with saliva magic while Bell Hydra seeks the stolen Black Curtain.

2

Staz enters Fuyumi's room, criticizes her lifestyle, and proposes transferring to her high school. He sprays her upset father with diluted saliva to control him, claiming it manipulates humans. Excited by the human world, Staz sprays the entire school population with his saliva, creating false memories that allow Fuyumi to blend in seamlessly. However, Fuyumi’s body begins to disappear, prompting Staz to have her drink his blood to restore her demon existence. Staz notes a lack of interest in drinking human blood other than from Fuyumi. They return home to find Bell Hydra, who reveals she did not willingly leave the Black Curtain and knew about Staz's doppelganger. Staz wrongly assumes blackmail, but Bell uses spatial magic to threaten Fuyumi’s life unless Staz retrieves an item from a demon clothing store. Bell explains she seeks the thief of the Black Curtain. After a pointless fight with the store owner, Bell reveals Fuyumi can only be revived by the Book of Human Resurrection, sold to Wolf, the boss of the Demon World's Western District. The episode ends with Staz shocked to learn Wolf is his old friend and rival.
