Moon Demon Company

The Moon Demon Company (月鬼ノ組,) is an elite military group that is famous within the Vampire Extermination Unit. It is commanded by Lieutenant Colonel Guren Ichinose. Squad leaders include Sergeant Shinoa Hīragi, Sergeant Makoto Narumi, and others. They work in squads of five or more because a smaller team might not survive an encounter with an armed vampire. This company emphasizes teamwork and encourages its members to think of each other as family.

Their weapons include mass-produced Enchanted Gear, Cursed Gear (including four bearers of the Black Demon Series), drugging up, and spellcraft.

Duty
The squads fight to exterminate vampires, capture or kill noble vampires, and rescue humans--in that order.

Along the way, it was even noted by Sergeant Makoto Narumi and his squad alongside others present with him are highly supportive of Guren Ichinose's leadership. Grudgingly, they wouldn't want any other high ranking officials above Guren to be their leader in the Moon Demon Company such as the Hiragi Family.

Trivia

 * Although Guren is only a lieutenant colonel and is therefore ranked lower than a colonel, he commands colonels Mito and Goshi.
 * Guren and his squad members have been on the same squad since they were 16, which was before the apocalypse occurred.
 * Promotions in rank in the Japanese Imperial Demon Army are often due to family status rather than success in battle or qualifications.
