ShadowEntity
Infraworld Entity
Kai wasn't suprised that he sensed a demon, he then chanted "O Spirits from the celestial kingdom, may your scared army march in the depths of battle and may your instruments of holiness, give me protection", though it took so long to chant the spell, it did summon a powerful celestial being with five heads and four arms, the being itself prepared it's bow and arrow as it aimed for the mysterious man. Kai standing there being protected cannot be defenseless, as he equipped his bow and arrow himself, as well.
