Odd, why did he had black hair as a child?

Probably dyed it to disguise himself

Yes. According to wiki this is the definition of the syndrome.
Marie Antoinette syndrome is a sudden whitening of the hair. The event that named the syndrome was the observation that the hair of Queen Marie Antoinette of France turned stark white after her capture after the ill-fated Flight to Varennes during the French Revolution. Witnesses have alleged that Antoinette's hair suddenly turned white on three separate occasions.
Like what happened to Kaneki ken of tokyo ghoul under the repeated torture, his hair turned white.
Though I realize Leon's hair is blond.. so im just putting it out here that this is a possibility. ^^"

i was a wig

Sooo, someone gimme a quick recall. Did Kaname actually die at some part and who is the Father again?
(● ̄(エ) ̄●)

He didn't exactly die, but he did in a sense sacrifice his life because the hunters' weapons needed vampireblood or something along those lines. Also Kaname is the father of the girl but Zero is the father of the boy (⌒▽⌒)

Wow, look at that Shit Ending. I mean like EVERYTHING just happened in those 40 Pages. Each new Page was a new Development that you can't fully enjoy or comprehend.
The whole Story Development was sooo slow at the Beginning. Meiko was beaten around and made fun off way to many Chapters to deserve such an half-assed confession, kiss and Ending.
Man, now im disappointed.
You guys are so spoiled with Shingo and Kagami who basically have no Plot whatsoever, that you dont appreciate a Story with Plot but without Dicks.
Looking at the date, Nekoka Danshi No Shitsukekata was her very first Story with Boys Love content.
