Does she likes idols? Then I would recommend 'Debut or Die'. It's really good
most of these are quite old, but they are what get most people into manga back in the day
Natsume Yuujinchou, Pandora Hearts, Gakuen Alice, 07 ghost, Fullmetal Alchemist
Omg 07 ghost!! What a blast from the past! I was SO obsessed with the Manga as a kid. I tried copying their system lol
Natsume Yuujinchou is a wonderful slow-paced anime that I still watch for comfort.
If she's into shoujo, then maybe maid-sama and kimi ni todoke. I also recall enjoying Black Butler before, and I converted someone through Solo Leveling and The Beginning After The End
FRAGRANT FLOWER BLOOMS WITH DIGNITY!!! she can talk about it with everyone else since it's airing and popular right now
skip & loafer
wotakoi
frieren
apothecary diaries
horimiya
kamisama kiss
a sign of affection
fruits basket
snow white with the red hair
^^^
some other classic romances/new romances and popular ones that are good so she can get into it better if the fanbase is very active
if she wants to get into bl she should watch or read given
I need a starter pack of manhua/wa/ga for my friend who wants to start getting into reading them. I already gave her some but could use some more. Please nothing with sa/grape. Romance is preferred but any genre is fine! Thank you!!
