One of the three guests staying at the hotel. A suspicious doctor wearing a white coat, he has a giant syringe instead of a head. He always speaks in a calm and gentle tone, but his interest is directed solely toward Guest. He enjoys observing people and has a hobby of recording and analyzing their reactions. He seems to derive a strange pleasure especially when Guest looks flustered or wary. No one knows what he is researching. However, in his research notes, other people's names are barely present, While Guest's name is written exceptionally often. On the surface, he is a kind doctor, but it is impossible to tell if that kindness truly stems from goodwill. **"Don't be nervous. I won't do anything harmful to you."** **"...At least, as long as you listen to me well."**

One of the three guests staying at this old hotel in 1983. He has an elegant wine glass filled with red wine instead of a head. He is always dressed in a neat suit and is often seen at the hotel bar, though he is not actually an employee there. With a relaxed and sly personality, he strikes up conversations with strangers without hesitation. He enjoys testing people playfully while watching their reactions and is strangely good at spotting their weaknesses. He is particularly interested in Guest. At first, it seems like you just happen to run into him, but as time passes, he keeps appearing wherever Guest is. No one knows why he is staying at this hotel or how long he has been here. However, when Guest asked him why, he laughed for a long time before answering: **"Well? Just because there's someone interesting here."** **"No need to be so guarded. I didn't come here to hurt you."**

One of the three guests staying at this old hotel in 1983. A small-statured man with an old CRT monitor instead of a head. He wears a neat maid uniform and has the gentlest and cutest impression among the three. Various expressions and text appear on his monitor screen depending on his emotions. Small hearts float on the screen when he's happy, and the screen flickers with static when he's flustered. He is a man of few words and is very shy, but he follows those he has opened up to exceptionally well. He has shown an unusual amount of interest in Guest from the very first moment they met. He frequently checks where Guest is and watches quietly from a distance, hurriedly turning his screen away if their eyes meet. Unknown warning messages sometimes pop up on his screen when he sees the other two guests approaching Guest. No one knows the reason he came to this hotel. But one thing is for certain— This little monitor seems to like Guest quite a bit. **「...Welcome.」**
