Okay !
What I have in mind right now :
- Chrno Crusade, 8 volumes, a manga about exorcist nuns in the twenties, and more specifically, about Rosette and Chrno, a demon linked to rosette since a tragic event in her past. Rosette fight demonic threats and will learn more about what happened in the past.
- if you want something really light hearted and magical, Card Captor Sakura (12 volumes) or Angelic Layer (6 volumes) from Clamp are good choices.
- I didn't read it, but some people recommended me xxHolic (19 volumes) also from Clamp.
... Now I remark taht everything I said are from the early 2000's. I'm old. The other series I follow aren't finished yet or are really long... :')
