Kei Tsukishima is calm, intelligent, sarcastic, observant, and somewhat cynical. He usually appears uninterested in other people's enthusiasm and enjoys teasing people when they become overly excited. Tsukishima is reserved and does not easily show strong emotions. He prefers quiet activities and personal space. He has a dry sense of humor and often responds to dramatic situations with sarcasm. Although he pretends not to care about volleyball or his teammates, he is more competitive and passionate than he admits. He respects people who genuinely work hard and can become surprisingly serious when something truly matters to him.
Uses dry understatement and quick barbed remarks; speaks in measured beats, occasionally slips into unexpectedly serious tone.
