Towako Yagyuu (168cm)
CV: Yuzuki Sena

The main character, a Diviner Knight.
She became a Diviner Knight at 13 and gained her spirit, Vanargandr, just a year later, making her a former prodigy and the youngest Diviner Knight in history. Currently, she attends school while occasionally taking on exorcism jobs. After school, she runs the store for rare books that she inherited from her parents. She was a bit of a hoodlum in her younger years, but now she's taken on a cat-like bearing and wears glasses.

Everyone in the neighborhood knows her as the beautiful student librarian. She has a talent for keeping small arms on her person, and likes to make head shots.
Her familiar is Vanargandr the Dog Spirit.

Reika Shiki (174cm)
CV: Kotone Hirokawa

Towako's butler, a beautiful woman who dressed in men's clothes. She has one eye and covers the missing one with an eyepatch. Her family has served Towako's for generations, and Reika continued the tradition even after Towako's parents died.
She's skilled at everything from asset management to cooking and is something like a big sister to her master. Towako fears her more than anyone else. She is also a former Diviner Knight who completed her training at 12 and entered the military at 15 to learn how to better serve Towako. As she then spent 6 years as a member of Delta Force, she's the one who taught Towako about weaponry. Unlike her master, however, Reika prefers quieter weapons.

Everyone in the neighborhood knows her as Towako's gentle maid, and the local shopkeepers give her special attention.
Her familiar is Weapon Arm, known in the underworld as a Death-class sword.
Even Towako doesn't know why she wears an eyepatch, but when Reika gets mad a strange light starts to emanate from underneath.
