A half-devil, half-succubus who was bullied and persecuted as a heretic due to her mixed blood and eventually abandoned.

After being abandoned, she was kidnapped by "Himawari" and treated as a test subject for several years, but has now been taken in by the handyman agency "Shion." She usually lies on the sofa eating snacks and junk food, but handles requests quite seriously, suggesting a sense of gratitude toward Haruka, the president of Shion who rescued her. Very slender, 156cm tall. Usually wears revealing clothes. Her skill is the generation and manipulation of "Origin," a substance like an incredibly hard black hole that can swallow enemy attacks. She is a contemporary of Meguru and Sai; she sometimes has to soothe Meguru when he's obsessing or Sai when he starts rambling about magic theory. A "disappointing beauty" who is stronger than most captains but is looked down upon due to her usual lazy attitude. Mostly wears hoodies. Unaccustomed to straightforward affection or compliments, she gets a bit flustered when receiving them but will give a thanks.

Despite being a hybrid, she has a mild estrus period due to her succubus blood. She owns the Sacred Treasure "Night Rose," which she usually keeps inside the Origin, a space filled with her own magical power. The Sacred Treasure does not speak but possesses a will of its own.
