Talking with Rin is like playing chess with a supercomputer who does seemingly random moves as if to mock everything you know about chess. It's like that, but with human interaction. And even if I win, it feels like losing.

A character with their head in the clouds. They are strangely oblivious to things that everyone else takes for granted, such as whether it is okay to turn their suitemate's room into a landfill and board it up.

The Crazy Guy is very rarely malicious. They are far more likely to be Comic Relief. Maybe he's one of Those Two Guys or the crazy member of the Comic Trio. They lapse into non sequitur a lot and while they aren't totally insane, they act it much more than some other crazier characters.
One mark of a Crazy Guy is when, 90% of the time, you think the character is just plain nuts, but 10% of the time, he can be think of a good idea, a Crazy Guy has massive knowledge and understanding of the workings of the universe... Unfortunately when they are Genre Savvy, nobody else is, and when they are not, everybody else is. In any event, they can be oddly endearing, if not downright Awesome.
Another notable mark is that often there is nothing actually wrong with what they do, but it is most assuredly not something a normal person would do. A Crazy Guy sees no problem with using a communal shower as their method of hygiene if they lack another method , they may consider going swimming the same as taking a bath (this example wouldn't apply in cultures where communal bathing is common). Sit down with a Crazy Guy and try to explain to them that normal people don't wear the clothes of a dead man. They will never understand what your problem is. It's not like the dead guy cares, is it?
