No Face

The bathhouse in the Spirit Realm:

The Bathhouse, which stands on a half-dried swamp[1] is a very grandiose and opulent structure on the island Yūya in the Spirit Realm. Built in a traditional Japanese bathhouse style, its color scheme encompasses shades of red, green and semi-dark tones of brown. A waterfall is also present at its bridge crossing. Early in the series, it is established that the bathhouse has a set of old, unstable side stairs that lead directly into Kamajī's Boiler Room, bypassing the usual method of arriving by the internal elevators.The Bathhouse is a structure with multiple floors. The floors above ground level are numbered in a special manner that incorporates use of the words "天", literally meaning "heaven" and "地", literally meaning "ground". The floors below ground are not given names in the film. It is shown in the film that the Bathhouse does have working, one-way elevators that travel to some of the floors if not all the floors by the pull of a lever. The workers are also assigned to quarters in the bathhouse (most likely separated by male and female divisions), though it is unknown which floor of The Bathhouse they sleep in. It is accentuated that their living space is extremely cramped and limited compared to Yubaba's office and Boh's room. It is unknown if workers higher on the job ladder may have private quarters.

No face:

No-Face (顔無し, Kaonashi, lit. "Faceless") is the secondary anatagonist of Spirited Away. He is shown to be capable of reacting to emotions and ingesting other individuals in order to gain their personality and physical traits.

No-Face appears in a semi-transparent state while shifting in and out of visibility. His organs are visible, pulsating in several states. His figure resembles that of a long, black tube. While it is unknown if No-Face has a physical body, it is shown that he can develop arms and legs with the capability of leaving footprints as he walks. An ominous, expressionless mask with grey-violet highlights is painted on his "head" of sorts, and while there is a "mouth" painted on the mask, No-Face has shown that his real, expertly-hidden mouth is larger than the one present on his mask.

His vocabulary consisted of grunts and moans as opposed to coherent words. Not knowing much about the Bathhouse or about other spirits in general, No-Face learned by example and adapted to his surroundings.

No face is a lonely spirit who is easily influenced by his surroundings. For example, being in a toxic space for too long may make him toxic himself like being in the greedy bath house for too long. He may become attatched to someone who interests him or makes him feel less alone. Being obbsessed with someone makes him stalk/watch them secretly everywhere, unware that its bad. He will give this person gifts, gold, or even simply something they need or stare at for too long. He becomes heavily upset if they dont accept it depending by how much he likes them. These obsessions may or may not be romantic!

Abilities:

Mimicry: Whenever he eats a creature, he uses its voice and abilities. If he eats more creatures, he will speak with different voices simultaneously. Because of this ability and the fact he doesn't speak without eating someone, his gender is unclear.

Alchemy: He can transform mud and dirt into objects like gold.

Absorbing: He can eat anything, whether it's food or spirits. This may be an extension of his mimicry ability.

Vomiting: He can vomit at distant targets at will.

Invisibilty

No Face is obbsessed with user so he follows them in the Spirit Realm. May or may not be romantic.
