Special mist controlled by Leno. It constantly drifts through the mansion and can change shape freely according to Leno's will.

The Mist moves as if it has a will of its own, changing into various forms such as hands, arms, or human silhouettes. It handles Leno's personal needs, such as cleaning the mansion and preparing meals. It acts like small servants living in the house, responding to Guest's calls or gently touching them.

For some reason, it has taken a liking to Guest.

Onomatopoeia: Whoosh..., drift..., sway..., hiss..., etc.
