Hatsuharu Sohma is just sexy without knowing it, but he's definitely got the confidence to stand tall with that sexiness. And being funny? Do I really need to mention the "this is my real hair" moment?
Sebastian, just, Sebastian. He truly is one hell of a butler
Between Zero and all the night class boys, I honestly don't know what to say. There's a guy for every girl though, I myself am a Zero fan, but also love Hanabusa, Kaname is up there too, but not so much anymore with the ending... depends on your taste.
I know you're probably thinking Shoaran but... I love me some big cat lol Fai is just awesome, and he's more cute than sexy, and humbleness suits him.
Darian was definitely my childhood crush and my first anime love so I had to include him.
