The "Yu" depends on which version you mean.

-Manga Yu: Is a jerk to everyone at first, becomes friendlier over time.

-Anime Yu: Is hollow and emotionless at first, kinda dull and boring. But gains more and more emotion as the story goes, before becoming a pretty emotional one behind his calm demeanor.

-NG+/Golden Yu: A complete Ace in every single area, both in and out of combat, reaching borderline Marty Stu levels. But it's justified, as in this case he didn't become strong, he is starting strong (social-stat wise anyway).
