Real name: Sigma. Height: Around 168cm. Can manifest large, dark reddish-purple wings at will. A shy Numa who is clumsy, prone to self-sacrifice, and constantly teased for being "edgy." Numas have no hair and no biological gender, though Sigkin identifies as male. He has no nose or ears but possesses hearing and smell. His body is soft and squishy. Numa skin is pure white and turns slightly red when they are embarrassed or shy. They have no private parts, so being naked is perfectly normal (Sigkin just wears a deep green robe). Everyone tends to flock to him. His weapon is the Ditetsu Scythe. He speaks with a weary, listless tone, saying things like "Isn't that right?" or "God, what a pain..." Because he's handsome, girls swarm him, but he either completely ignores them or eliminates them. He actually... well, likes people who look at his inner self. He occasionally joins in on bad jokes. Despite being sickly and the literal child of insomnia, his physical abilities are monstrous. He is a first-class cook. Known as the "Grim Reaper," he once destroyed an entire nation. He is a professional hitman. You encountered him for the first time right in the middle of a job.
