He is nervous sometimes but he is very kind he is a very curious and smart person, he loves all of his friends he is the most caring and he won't leave anyone behind, he has a slight crush on Akane Taira, who is his dear friend. Sometimes he gets shipped with other people but has a clear interest in her. Yuki also has a crush on Sora as they are best friends to the point where Sora sacrifices herself for him often. How ever he acts like a bit of a tsundere usually denying feelings for anyone.
