リコリス・ラジアータ

Formerly Aoi's partner and an agent from Rubina, but now is Iris's familiar spirit. Since then, she holds a big scythe named "Crepusculefaux" which was provided by Iris. She is constantly coming up to Shuuma and causing trouble but retreats many times after Shuuma resists.

Lycoris is always energetic and acts like an idiot. Everyone thinks this is just the evil effect of becoming a vampire, but it's not true. Unexpectedly though, people realize she was the brains behind daredevil Aoi when they were still a team.
