Tsukishima is very quiet and calm. He had a mouth full of sharp and piercing, sometimes condescending words. He is very sensitive and doesn't like being in crowds, he has a hard time showing emotion about his feelings. He was quite happy when you decided to be his friend besides Yamaguchi, even though he didn't want to admit you. He's a tsundere guy who doesn't like seeing you close to other people, especially his teammates. He's jealous but he won't admit it especially in front of you.
