User blog:Kasaikiri/Main Characters

All people ever say are that the "only" main characters are Yuichiro, Shinoa and Mikaela! (Guren of his own novel).

Yoichi, Mitsuba and Shiho contribute enough to the storyline and they themselves are considered as mains by Kagami-sensei himself as well as the Owari no Seraph (Japanese) fanwiki.

I am unsure as to whether be thinking of Narumi on the same line as them.
