Hes a Trap
Facts about Eriko:
-Miku is confused for being the Youngest daughter.
-When he was eight out on an "adventure" he was cursed by an Yama-uba to die of old age. Oyuki (great-grandmother but not by blood) found him when visiting Hideaki(great-grandfather).Eriko was rapidly aging on the inside and slowly on the outside so she was able to know who he is. She rushed him to Sojobo where they rested Eriko in the pond and Oyuki froze it to preserve Miku's life. Oyuki wept for the child's life while Sojobo tried to heal him. It took many days for them to find a way while the pond slowly melted.
They went over all different ways to help Eriko examining his body countless times. It was was a small chance to reverse it making it would make things difficult on Eriko if her lived. Eriko's eyesight would always be poor and his growth would be stunted for an extended period of time but he would live. So Hideaki centered the curse in the pupils blinding for a short time then pulling the pupils out of his eyes. Oyuki handed Hideaki what looks like frozen tears that they would use in an exchange the tears for the pupils. Miku won't be able to see as well as a regular tengu but he will live and that was what mattered to the pair.
When the pond finally melted his body never gained much color staying pale. He still hasn't grown much since then he is no taller than five foot three.
-Eriko has pretty poor eyesight (he wears contacts if they exist if not glasses) but makes up for it for great hearing.
- He carries around a pair of pupils as a reminder. OK: You missed a 'tengu' replacement, but another question: How does he 'carry around a pair of pupils'. Does he actually carry a pair of eyes with him? Also, the pupil is the center part of the eye, which is black/colorless. From your drawings I think you mean the
Iris?
You've also made him extremely standoffish. He hates people, he's a psychological bully, apparently emulating the people who bullied him in a stroke of irony, but he also doesn't like to talk to people, and apparently has a good pokerface. ((Or anyway he's permanently set on 'madface'
wink ))
If he's so standoffish, and literally trusts -no one- at any level, you're going to find it extremely difficult to interact with people on a repeat basis, since he has no reason to want to. This may work fine for a time or two, but it'll become harder to find reasons for people to want to interact with him a second time if all they can expect is staring, the occasional brush off, and the poker face. I think you'll want to take into consideration things that would make him want to interact with people again, outside of the 'Damn I've got to' classroom setting, or potentially make it something you aim for as an rp goal.
