NEGI

NEGI is Hitsugi Kurone's older sister. The two of them share a body, so she likely transferred into the producer course of Yumenosaki Academy when Hitsugi did. Despite being in the producer course, NEGI has gained a fanbase from singing at the live house. She acts as if she were a frail corpse, which could be a testament to her necromancy skills or to her origin.
