round about the end of the hole devil elf ark, I'm pretty sure some of the elves get their own body's and if I'm remembering correctly Fana along with Betti are the 2 that gain there own body's along with some more elves at the end of the ark
Elf Fana is a good idea or Nero for me fana is more helpful to the mc and has fire magic so they can team up and Nero has good magic but in society and helps him as a friend or as a son or brother
Puedo recomendar a SOL MARRON miembro de las Rosas Azules.
Su actitud alegre y burbujeate le hace perfecta ya que al ser muy animada eso le hará feliz a la vida del MC.
Aparte su magia de tierra y la magia de fuego sería interesante una descendencia con magia de Magma/Lava de ambos
you do know that after the witch forest elf fana gets her own body that would look like it is the same age as Asta so basically she would get a complete rebirth without the risk of something causing her soul to release human fana's body and disappear
I’d say go with your gut if you think Fana is a good main girl then go for it’s an interesting concept. Though maybe keep mars as a brother since seems like a characte you can make into something
