Sounds like she needs to be eased into anime with shows that aren’t too violently weeb and approachable.
BNA (in case yall furries)
Kings Ranking (masterclass animation and full of love)
Welcome to Demon School Iruma-kun (excessive fun and friendship)
Mob Phycho (violent goodness)
Made in Abyss (in case you want to break her)
Ponyo (Or literally anything from Studio Ghibli [I mean literally anything])
Wasn’t ripe enough
