Galgali and Kobeni

Kobeni is a young woman with short brown hair tied in a ponytail with shoulder-length bangs/strands of hair hanging down to the right, brown eyes with white pupils, and she has four moles on her face: two under her left eye, one below the right side of her mouth, and one on her left cheek.

She usually wears a business suit and has two red hairpins on the left side of her head.

At the rookie party, she wore a dress passed down from her older sister, which several other demon hunters thought was cute.

Kobeni is typically shy, quiet, and often anxious. She is exceptionally cowardly, with rare moments of bravery. Her first encounter with the Eternity demon leaves her paralyzed with fear and babbling. She is shown to easily break under pressure and cry when the group is trapped in a hotel and faces the possibility of starving to death without any help. Her fear can also make her noticeably clumsy.

Despite being forced to work a job she hated with her family, Kobeni still cared for them, sending money to her brother to support him through college and driving her family around in her car. And despite wanting to quit, she initially stayed because it was the day she was supposed to receive her bonus.

Kobeni is shown to enjoy alcohol, especially when someone else pays for it. Her hobby is eating delicious things. She loves the flavor of ice cream, which she's only tried three times in her life.

Kobeni, besides his parents, has 8 brothers and one older brother, as well as an older sister.

Galgali, the Fiend of Violence, who embodies the concept of violence and is a public safety demon hunter from the Tokyo Special Branch 4.

Galgali possesses the corpse of a rather thin man, dressed in a hooded suit and wearing a plague doctor's gas mask, which obscures his facial features. He wears muted colors such as gray and beige, with a hint of yellow.

Despite his nickname, "Half-Demon of Violence," Galgali is extremely polite and straightforward. This is first shown when he apologized to Bim after striking him in self-defense and told the Spider Demon to leave the area when he mistook her for a human woman. Galgali explains this by saying that he still retains a significant portion of his human brain, which is unusual for a fiend. With some irony, he claims to love peace and love, and remembers many details of "his past life as a human." He claims he can't eat because of his mask, but he enjoys treating others because he can enjoy the food through their reaction to it.

The Half-Demon of Violence possesses extraordinary strength for a half-demon, despite the fact that half-demons are typically weaker than demons. To contain his strength, he is forced to wear a mask that sprays poison. Although his poison-spraying mask weakens him, he shows no signs of ill effects from it. Galgali can access her power and transform parts of her body into a freed state. This causes the limb to enlarge and gain muscle mass, becoming incredibly powerful. The half-demon of Violence's primary fighting style is unarmed combat; he can knock back Beam with a punch and decapitate zombies at point-blank range with a kick.

Galgali also has a very good relationship with Kobeni.
