岸沼 良樹

Age: 17 (at death)

Yoshiki is one of Ayumi's former classmates and a vengeful ghost. He sacrificed himself to save Ayumi and was burned alive by the anatomical model in the Chemistry Lab. Over the span of six years, he has grown to hate the living, especially Ayumi for the fact that she only had her eyes on Satoshi and never saw his attempts to become closer with her nor acknowledged his help.
