Absolutely!! He is such an interesting and stand out character compared to the others. His personality is very lowkey 'n quiet, and he has a calm and sleepy voice to match. I also like the use of blue and red in his asymmetric design. Cyan and crimson. Blends very well. Just a lot of cute details on his design. Especially the hair antennae, and how it moves.

I really really vibe with his personality in general. He is one of the few characters I can confidently headcanon as autistic. I see a lot of those traits in him and his mannerisms. He doesn't express himself facially much, is hyper interested in bugs and can recall a lot about them off the top of his head. But he also struggles to pick up other bits of info. His voice also tends to sound drab, or lacking emotion. Only a couple of his friends can tell how he actually feels about things in the moment. His diction is blunt and to the point (In Japanese dialogue he doesn't use a personal pronoun, which is not something I've heard of often). It's all very, uh, clear, stand out to me.

He is in a way simple and deep. He feels things strongly, but doesn't show it in a "regular" way. He cares about his friends a lot. He's empathetic. Sometimes he puts others before himself, not wanting them to worry about him. In combination with everything else I find it cute and sweet.

I also think his backstory is interesting. He is (the descendant of?) half of a demon, the other half having been sealed in a book long ago. That's why his left arm is red, and it seems like it became that way due to proximity with that book. He doesn't know all the info about this but he doesn't like thinking about it. And the concept of, the red of the arm spreading, scares him too. The whole idea of losing yourself. He wants to enjoy life at his own pace. Maybe that fear that the opportunity could be taken from him is frightening, but he doesn't know what to do about it... So he tries to think about other things instead. Such a sad thing. I am attached to it though. It touches me, I guess...

Sig is very comforting to me, in general. I enjoy thinking about him. In lots of ways. Being in distress, or being creepy, or being supported and loved. Happy about him <3
