Hell Girl

Inao Kaede, a quiet student, claims to be a fortune-teller through a fox spirit she claims resides within her. As she makes a streak of strangely correct predictions (later revealed to be just lucky coincidences), more students begin to give her requests. A shallow student, Nishino, requests that Inao kill a college student she claims is stalking her. Inao reluctantly accepts but no matter what she tries, the 'stalker' lives. Threatened to be exposed as a fake, she resorts to sending him to Hell, only to find out that Nishino lied to her and she'd damned the guy and herself for no reason. Nishino just wanted him dead because she found him gross. The guy had been innocent.
