Sagi's Links
Childhood friends. He welcomes Jeul's fights as she tends to help demonstrate to the young in the village what they can aspire to be. He feels the silence when Jeul disappears.
Prissy ass Sagi is the perfect target for practice, he's got skills she really likes sparring against.
Jealous. Sagi takes too much of Maru's attention. Otherwise previously he did respect Sagi as a teacher, though he never really pays much attention in class
I don't think either of them are aware of this directly, but sagi might know of a relative who seems to have gone off the deep end
