This chapter felt like a major turning point,the more I read it.He summoned the Kali,killed a hi-ranking Mori member 'in front' of other hi-ranking members will definitely 'rock' the world of onmyojutsu.
For the whole story itself,I actually liked the plot,settings,and I kinda also gained some extra knowledge while following the story.The historical lessons and magic info adds spices to the story itself.
Plus,the fluff tween Sei and Subaru is just cute ^^
