Cube×Cursed×Curious

The anime can be shortened to C Cube or C3. Yachi Haruaki is a high school boy and naturally resistant to curses. His father, Honatsu, sends him cursed instruments called "Worse" to try to break this.

One day, Haruaki receives a black cube from Honatsu. That very night a sound wakes haruaki that came from his kitchen where he finds a naked girl who was stealing their food. The shock that takes Haruaki for this girl is the first of many to come. She is the human-form of the black cube, an instrument of torture called "Fear in Cube". Haruaki and the girl 'Fear' fight together against other 'Worse' instruments and their owners using Fear's 32 mechanisms of torture.
