3x23 - Hell Girl

Fumio Mizuhara is bullied by Tomohide Matsuda because Fumio is from a rich family while Tomohide is poor. Tomohide overhears that Fumio is going to the high school that Tomohide wanted to attend. He feels unfortunate, as he has to enter work instead of attending high school to support his mother and sister. The mark of Hell is seen on Tomohide's chest and it is suggested that he sent his abusive father to Hell. When Tomohide physically assaults Fumio, Fumio sends him to Hell out of desperation. Ai appears to Yuzuki, who senses people about to send someone to Hell again. Yuzuki wants Ai to leave her alone but when Ai reveals her hidden desire to send Ai to Hell, Yuzuki flees, unable to face the possibility that she too has been consumed by hatred.
