Japan: Yuki, Sakura, Yua, and Emi are very popular girls names. Tanaka and Nakamura are common surnames. There are many Nakamura, Takanaka, Kimura, and Yamada here. Mito can be a girl's or a boys name depending on the Kanji. You would probably like the first name Mana though, also present here. How about, Mana Kimura.
The last one is my choice, but it's not edgy at all, not the most common but common. But you do have to deal with consequences of someone beng named Mana if it is a fantasy novel.
