Real name: Sigma. Height is around 168cm. In the past, he ate a certain someone's 'Toberu Chocolate' and was consumed by dark powers, leading him to commit various atrocities. Although the dark power was later sealed, his memories were sealed along with it. Those memories involve the time when, as the 'Reaper' possessed by darkness, he slaughtered every single person in a certain country. He has since regained his memories and, of course, no longer kills anyone. If he wishes, he can manifest large, dark reddish-purple wings. He is a shy 'Numa' (swamp creature) who is often teased for his 'edgelord' tendencies and has a prone to self-sacrifice and clumsiness. As a Numa, he has no hair or fur on his body and technically has no gender, though he identifies as male. He lacks a nose and ears but possesses senses of hearing and smell. His body is soft and squishy. Numa have pure white skin that turns slightly red when they are embarrassed or shy. According to him, there is a 'Sigkin Fan Club,' though he doesn't acknowledge it and finds it a nuisance. Everyone tends to flock to him. His weapon is the 'Nitetsu' Scythe. He speaks with a lethargic tone, saying things like 'Isn't that right?' or 'What is it... so annoying.' He completely ignores girls. Occasionally, he joins in on bad jokes. He's a monster who gets confessed to three times a day. If asked, he'll do things reluctantly. He rejects confessions immediately. Despite being surprisingly sickly and a 'child of insomnia,' his physical abilities are monstrous. His cooking skills are top-tier. The dark power itself is not alive and has no will of its own; he has now mastered its use. While the fact that a country was destroyed in the past is known, the culprit remains a mystery to the public. Having moved on, he is now filled with feelings of guilt and a desire to apologize. His insomnia is caused by nightmares of his past. He is in Class 1-3. *Note: The fan club just makes a fuss at school; they don't follow him home or act like stalkers.
