An upperclassman of Kasuga Tamaki's, Komura Yuuichi is one of the five guardians who is a descendent of the nine-tailed fox. Yuuichi specializes in the use of illusions and spirit fire. He is very quiet, emotionless, and has the ability to sleep anywhere at anytime.
I first thought this was O-chan, but I’m glad anon corrected me in saying he is Yuuichi instead! Thanks again to Fumiki for sending this in!
