Kyousou Giga

 The Kyousou Giga.

  It's Kyoto, and yet it is not. A microcosm of peculiar origins, "Mirror Kyoto." A small incident causes a young girl, Koto, to wander into this world. She runs into a mysterious monk, gets chased around by a tech-obsessed girl, and heartily enjoys her chaotic and colorful new life, but meanwhile, out of sight, a certain plan is being set into motion... In this mysterious city where spirits and humans have been thrown together, the festivities are about to begin! (Source: translated from the official website by lygerzero0zero)
