NEGI is Hitsugi Kurone's older sister, and identifies herself to be the summoned soul of Hitsugi's late sister. While they share a body and she often assists Hitsugi in his work, NEGI does not consider herself part of Yumenosaki Academy's producer course. She instead prefers to spend her time singing at the underground live house, and has even gained a fan base. She acts as if she were a frail corpse, which could be a testament to her necromancy skills or to her origin.
