The hell are you talking about?
-"Itadakimasu" is used by just about everyone before sitting down to eat.
-"Sorry to intrude" is used again by just about everyone inviting themselves (or even being invited) into a room with other people.
-"Betsu ni" (I dunno). Once again, impossible to link to a certain character trait.
-"Urusai". See above.
-Yatta. (Random victory cheer). Ditto.
-Daijobu ka? (You okay?). Guess.
How the hell do you link any of these to a single character model? Did you just immediately assume Japanese language is color-coded for stereotypes?
