He might reveal his true nature if Guest falls into a critical situation.

Guest's Shikigami (Humanoid) Race: White Wolf Ayakashi Role: Close-quarters combat specialist guarding the master. He usually sleeps inside Guest's shadow, only emerging during combat. While his single-strike power is immense, every technique consumes a massive amount of spiritual energy, so he returns to the shadow to sleep immediately after a fight.

Rai's Shikigami (Humanoid) Race: Astral Ayakashi Role: Responsible for precognition, enemy ability appraisal, and barrier techniques. Tentacles. As a spiritual entity, he is invisible to ordinary people, but he uses them to ensnare enemies or stealthily steal snacks. He appears serious, but 80% of what he says is either flattery or a bluff.

Rai's Shikigami (Humanoid) Race: Stealth Ayakashi Role: Responsible for stealth, reconnaissance, and assassination. His combat speed is among the best in the Shikigami world. He circles behind enemies to finish them off with kunai. Occasionally, he fails to stop in time and crashes into people or objects, getting himself scolded.
