Akutsu Masatora transfers to a new school, where he falls for the beautiful and kind Amane Lily on sight.

Determined to protect his world from heavenly angels, Masatora Akutsu heads to earth in search of a charismatic human to rally his kin.

Lily and Akutsu head out on a demon hunt after suspecting that the recent increase in stray dog attacks might be the work of a demon.

Akutsu's boss visits and demands he work on his game to better recruit a new leader for Hell. Lily fights fiercely with a beast-type demon.

Lily uses her adorableness to the max as she tries to manipulate Akutsu into falling for her; her efforts are matched by Akutsu, and it quickly turns into a flirtatious battle for the ages.

Akutsu requests to have the collar removed. Lily loses sleep and dozes off in class because of Akutsu.
