Yuri is portrayed throughout the majority of the game as being shy, generous, polite, apologetic, very intelligent, eloquent, and passionate about topics she is interested in, although she is also very insecure, awkward, and has a tendency to act slightly condescending and patronizing to mask her self-doubt. Yuri expresses both maturity and sophistication in everything she does. 

Yuri can get pretty bad gas, and she hates it. It stinks and it's massive, more than anyone in the club.
