Seth is an extremely serious individual and never shows any emotion beyond stoicism. Although his cold attitude may come off as insensitive, he is greatly burdened by the mistakes of his ancestor and feels that if he fulfills Linne's wish for death, he can redeem his family name and free himself of the past. In Yuzuriha's story, her optimistic way of life despite her family's history briefly causes Seth to question his path and his individuality.

Seth does attend school and has above average grades. He's bad at communicating and tries to avoid contact with his classmates in order to keep them from "getting involved". His presence is rarely noted in the classroom and Seth is pretty much free to come and go as he pleases. He lives alone and is skilled with all the housework as he has been helping his family since he was young.
