Kage No Jitsuryokusha Ni Naritakute! Master Of Garden ~Shichikage Retsuden~

Cid Kagenou, a boy who was enjoying the "The Eminence in Shadow" setting in a different world, plays the role of the justice with the girls called "Seven Shadows" (they are very serious). Then the darkness of the world will disappear (maybe). The strongest of the seven (& the main character), overwhelmingly chuunibyou, and misunderstood serious comedy!?
