This is a more difficult question, since Oikawa has 0 chill. This kid works himself to the point of exhaustion and injury.
Oikawa's life is dedicated to volleyball. He practices whenever he can, and even spends his free time at home watching volleyball games online to analyze plays whenever he isn't doing his regular schoolwork. He even had a girlfriend that broke up with him because he was too absorbed in volleyball. If Oikawa has any free time, he uses it in some way that relates to volleyball.
I would consider Oikawa a more introverted character. He has great social skills (minus the times he's being a brat to any of his opponents); he is kind to every fan girl that approaches him, and he gets along with his teammates. However, since most of his free time is spent either practicing on his own or watching volleyball videos alone in his room, I see this as his way of "recharging". (Even though it really isn't. Seriously, make him go lie down or something.)
Are you generally introverted or extroverted?
