Komekko

Komekko is a very lively, sincere and cheerful kid. Because of her chūnibyō personality, she is very enthusiastic about "coolness", geeking out around anyone who could be considered "cool" and "awesome", which is why Komekko has high expectations for her Big Sister. She is quite free-spirited for someone of her age too, as well as smart, inheriting the keen intellect of her clan, given how quickly she solved the puzzle Host was struggling to complete. Also, since her family is too poor to afford proper meals, Komekko became a gluttonous kid, who stuffs her mouth with food and is unwilling to share a single bite. On the top of that, all she thinks about is eating, being capable of saying anything for treats, even if it hurts her beloved big sister's feelings. Komekko is quite cruel too, not only capable of cooking cute pets, but even humanoid monsters, also to fatten them in order to make them a hearty lunch. Although she doesn't have malice, but due to her family's upbringing (especially her big sis' teachings), Komekko is very mischievous, often charming adults with her cuteness in order to score treats, believing such behavior is the norm. thumb|Komekko scaring the demons who tried to take away her "lunch" Lastly, thanks to her innocence, Komekko is a very approachable, as she can make friends with anyone, even a demon, to the point of him offering to be her familiar in the future. On the other hand, Komekko can be fierce like a beast when she is angry, enough to frighten even demons.

Komekko greatly resembles her older sister in regards to their facial complexion, and shares the characteristic of Crimson Demons— red eyes and straight brunette hair (black in the novels). According to Aqua, 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.

Just like her older sister, Komekko has a huge potential as Arch Wizard, being very intelligent and skilled in witchcraft. Moreover, according to Host, she also has the qualities to become a Demon Master. *Demon Summoner: 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 a small-version of Host, a high-ranked demon, with shell of a cicada as offering. *Demon Tamer: According to a succubus, Komekko has an incredible talent to control demons, to the point the succubi couldn't leave her alone in the Adventurer Guild, which could be dangerous to them.
