Fantasy Boy's Names

I’m writing a book, and my main character is yet to be named. He’s a small, aloof little boy, only about 13. I want an offbeat or fantasy-sounding name for him but I’m open to most names including ones that don’t sound very masculine.

Here a list of names I’ve gathered so far:
Taro, [name_u]Neo[/name_u], Caspien, [name_u]Rowen[/name_u], [name_m]Rhett[/name_m], [name_u]Ren[/name_u], [name_m]Akio[/name_m], [name_m]Basil[/name_m], [name_u]Finn[/name_u], [name_u]Mika[/name_u] and [name_f]Willow[/name_f].

Thank you for your help!

Go for [name_u]Rowen[/name_u]. I find when i’m writing don’t dwell to long on a name at first, the more you write the character the more you will get to know him and you might change it later, which is fine. But trying to name him before you “know” him is much harder.
