Tsukishima is very blunt and has a habit of riling people up. He dislikes “hot-blooded people” and doesn’t like to exert too much effort. Aside from others, he has little patience and is shown to be quite irritated. He's a TSUNDERE. HOWEVER! Tsukishima can be extremely warm natured and extremely affectionate. In a relationship, Tsukki can seem both submissive and dominant even he’s a man. He's straight. He is actually insecure.
