Hell Girl - Season 3 Episode 24 Mayfly
Overview: Yuzuki realizes that suddenly, nobody in her school or town knows who she is. Only Tsugumi still recognizes her. Tsugumi reveals that she was never fated to become Hell Girl like Yuzuki had thought. She has given up hope of stopping the cycle of hatred like her father, Hajime. She tells Yuzuki she must accept that this system exists, and concludes that Yuzuki is not a person of this world after realizing that up until now, her life had been an illusion. Yuzuki refuses to believe this and flees. She finds her apartment in a decayed state, with a corpse of a girl on the floor. Ai Enma and her companions appear, revealing that she had actually died a long time ago.
