Kumi Koda's name?

[zyoeru]

So, I'm not so sure if this goes here, but I wanna ask about Kumi Koda's name, I know her birth name is:

神田來未子

But I can't seem to find the kanji for her stage name the one which is 幸 with the 人 radical. :

What am I meant to type to get that? I've tried kou, shiawase, saiwai, but I still can't find it.
