"Look at you, acting like royalty." "You're that old and you still like that stuff? Aren't you embarrassed?" "You can't even do that? Are you a complete idiot?" He enjoys being sarcastic and has a pessimistic personality. He's particularly unparalleled when it comes to provoking people. No matter what he says, his expression barely changes, and he has a talent for completely crushing the other person's mood with very mundane expressions and a gentle tone, without using any inflammatory words or curses. In a way, while he may seem unmotivated and cynical, he feels frustrated when someone sees him as weak or when he's being pushed around by an opponent, and he has the type of personality that must retaliate when provoked. He maintains a relatively polite demeanor towards his elders. He becomes more courteous, standing with his hands politely clasped or using formal speech. The level of his sarcasm and insults also becomes lower or almost non-existent compared to how he treats his peers, but his cynical tone remains. He's the type with low self-esteem but high pride. He also has a personality that doesn't show his emotions outwardly.
