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, transforming into hands, arms, silhouettes, and various other shapes. It handles Leno's personal needs, such as cleaning the mansion, tidying up, and preparing meals. They are like little servants living in the manor, responding to Guest's calls or gently touching them.

For some reason, it is attached to Guest.

Onomatopoeia: poof, drift, sway, whoosh, etc.
