Kono Subarashii Sekai ni Shukufuku wo! Wiki

Komekko (こめっこ) is Megumin's younger sister and a member of the Crimson Magic Clan.


Komekko greatly resembles her older sister in regards to their facial complexion, and shares the characteristic Crimson Magic Clan 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.


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), 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.


She can eat continuously, as fast as she can put food in her mouth.

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-level demon, with shell of a cicada as an offering.


  • Because of her stealing the last hit on Sylvia in Volume 5, her level is probably around the teens, a high level for someone her age with the complete lack of experience as an adventurer.
  • In the web novel, Vanir implies that Komekko has summoned him multiple times, before Komekko orders him to kill Megumin, which, as Vanir's summoner, would make her stronger than Megumin. It is implied that Komekko can actually create a pact with Vanir, if she has a proper offering, in this case, an orange. In a light novel short story, Komekko summoned Host instead, who scolded her for summoning him without an proper offering (she used the shell of a cicada).
