My sister wants to get into reading books but ngl I also mostly read manga as well. The only real recommends I have for her is anything by Sanderson so I'm here asking for recommendations. I'll provide a list of her fav manga so you can have a feel on what would be best to recommend.
List:
JOJOlands
Magi: Labyrinth of Magic
Sakamoto Days
Gachiakuta
Frieren
Holy Grail of Eris
Firefly Wedding
Sleepy Princess in the Demon Castle
Secrets of the Silent Witch
She Loves to Cook, and She Loves to Eat
