Karas

Humans live beside unseen yokai in Shinjuku, where the armored guardian Karas preserves a fragile balance. When the former guardian Eko turns against that duty and commands mechanized demons, the city needs someone willing to oppose him.

Chosen by Yurine, Otoha takes up the mantle while his human body lies helpless elsewhere. Fighting through Eko's forces, he must protect a city whose inhabitants scarcely understand the supernatural war unfolding around them.
