Wait, isn't Yuki a girl's name?

Yuki is a girl's name that means Princess.
But to be honest, the way he acts it fits him.

How would I know lol?

Yuki is a name for boys and girls, meaning its a unisex name ^^

well, i've mostly seen it used as a girls' name but i guess it could be used a a guys' as well =u=
other people named Yuki
-Yuki Nagato (The Melancholy of Haruhi Suzumiya)
-Yuki kreuz (Vampire Knight)

Not Necessarily..Yuki is unisex name (that means the name is gegeben to both boys and girls)..while Yuki is a common it might be gegeben to Mehr females than males in Anime it seems anyway doesn't make it solely a female's name.

Well, Yuki mean Princess,but....YUKI IS A PRINCESS!! in a way ;]

I think so

Yuki means snow.

It's also a name for both male and female, but mostly female I think.

It's a name for both girls and boys. Yuki Somah a boy. Yuki Nagato is a girl. Yuki means snow, not princess.
