Hell Girl (2005) : 3x3

Yuzuki and her best friend Akie rescue an idol, Jun Moriyama, from a stalker, and meet a woman, Masako Momota, who asks them to pass an envelope to Jun, containing photos of Jun in provocative outfits of the time before she debuted. Masako had attended the same talent agency as Jun but Jun bullied Masako until she could take no more and left, sacrificing her dream of becoming a singer. Ai's companions wonder if Ai is possessing Yuzuki because she doesn't have a body of her own in the real world. In the present, Masako makes Jun apologize, and demands that Jun vouch for her to debut. Jun refuses, stating that Masako cannot sing. At her concert, Jun attempts to make a public apology to Masako for her bullying, but an enraged Masako sends Jun to Hell.
