Host

Although he is an intimidating and prideful demon, deep down Host is very friendly and well behaved, as Komekko was able to touch his heart to the point he even promised to be her familiar if she summons him someday, albeit Host scolded her when Komekko did it without an appropriate offering. While he is boorish, Host is still open-minded too, even self-introducting like a Crimson Demon when he met Megumin and Yunyun. Furthermore, since, as a Demon, contracts are absolute to Host, he was fiercely loyal to his master Wolbach, even threatening Komekko's sister in order to fulfill his duty as a Dark God's servant.

Host appears as a towering and muscular figure with pitch black skin that has a metallic luster, as well as white eyes with no pupils. He has two pairs of horns: one pair sprouting from either side of his head, and the other pair protruding from his cheeks. He has giant bat-like wings jutting out of his back that allow him to fly at high speeds, as well as sharp teeth.

Host is an extremely powerful demon, even stronger than Arnes, whose powers are comparable to the Devil King's generals. *Immense Strength: Host posses a great strength, being able to defeat Rex's party and destroy an entire field, both with a single punch. *Magic Resistance: As a demon, Host has a high magical resistance. According to himself, he could even survive Megumin's Explosion if he was at full strength. *Flight: Host has the ability to fly using his wings. *Advanced Magic: In addition to high physical abilities, Host is able to cast Advanced Magic. **Inferno: Summons enormous flames that incinerate the surrounding area.
