Shinoa Hiiragi is Guren's sergeant and one of the squad leaders of the Moon Demon Company. She is appointed to supervise Yuuichirou during his suspension from the Japanese Imperial Demon Army for his reckless behavior. She is sarcastic and enjoys teasing others, especially Yuuichirou.

Her Demon Weapon is Shikama Douji (四鎌童子, lit. Four-Scythe Child), a manifestation-type demon weapon which takes the form of a large scythe, but can be condensed into a pen-like object. She can call out the demon, which she fondly addresses as "Shi," inhabiting it out of the weapon to attack an enemy. Her primary ability is to detect anything that comes within the attack radius of her scythe.
