- Is it Kobayashi Satoru?
You got it! Impressive 
It turned out to be the only one who met all three conditions.
Perhaps it was luck, then. But 5 questions ought to be enough.
Alright, new round.
Difficulty: Brutal!
This character is non-human. It’s related to something that’s become somewhat popular.
Go!
Will keep tabs for your convenience:
- It is not an A.I.
- It is not an animal
- Not animated (cartoon, anime, etc.)
- Doesn’t have a face
- It moves
- It is not larger than an average human
- It is neither monster nor ghost
- It is very much smaller than the average cat.
- It is not a germ
- It is not the size of a germ
- It is made by humans
- It is three dimensional
- There is plenty of evidence of its existence.
- It is related to r/theocho
- I’ve lost my marbles—ajem—I mean, it is a marble
- It is not from Team events
I can’t resist…
- Is it an AI?
- It is not A.I.
- An animal?
- It is not an animal
- Is your character animated?
#3. No, it’s not animated.
- Does it have a face?
- Interesting question. It does not have a face.
So it’s not a clock. 
- Is it mobile?
- It does move. Someone very nitpicky might say it is not (technically) mobile though.
This is hard but I will guess it is a fan, is that right?you said it is not mobile like the device I am using now and my question is what color it is or is there even a specific color
Can’t you just ask a more general question? We only have 20 of them. Just randomly guessing is wasteful…
A Yes / No question. I think we went over this before…
I will advise not to ask that question. It is a character, a proper character, not merely an object.
I have a secret protocol as to which questions I will answer. I will not say what that protocol is, but it is a fair one.
Also can we do guess the food?in another topic not this one of course
