Komekko

Komekko is Megumin's younger sister and a member of the Crimson Demons. 6 years old

Appearance: Komekko greatly resembles her older sister in regards to their facial complexion, and shares the characteristic Crimson Demons red eyes and straight brown hair. In the Light Novel art depictions, Komekko is basically a mini version of Megumin. Komekko keeps her short hair tied in pigtails with red ribbons and occasionally uses a yellow star-shaped hair-clip on her bangs. As a result of her family's financial situation, all of her clothes are Megumin's hand-me-downs, so her mage cloak also has some noticeable patch works.

Personality: Komekko has a lively and cheerful attitude. Like her sister she is very smart (demonstrated when she solved the puzzle Host had been working on far longer) and cunning, but still shows a great deal of childish innocence. She exhibits a constant hunger, eating whatever is put in front of her, and has tried to cook Chomusuke on several occasions.

Abilities: She can eat continuously, as fast as she can put food in her mouth. She is also incredibly intelligent, as show by solving the Dark God's seal puzzle. Demon Summoning: Komekko is an extremely talented demon summoner, being able of realize extremely difficult and delicate rituals even though it would take at least a decade of hard work to summon even the weakest type of devil, being able to summon Host, a high-ranking demon, with shell of a cicada as an offering. Demon Control: According to a succubus, Komekko has an incredible talent for controlling demons, to the point the succubus couldn't leave her alone even in the Adventurer Guild, which could be dangerous to them.

Chomusuke: Chomusuke is a black cat with a red cross-shaped marking on her forehead and bat like wings. She has stubby legs, a big round head, and yellow oval eyes. When she's happy or angry, she shows sharp teeth.
