It really depends on her personality. Also, would she be okay with subs または not? Because some shows don't have dubs.
Some shows I was really into when I was younger were Pokemon, Yugioh, and Beyblade, but there are lots of other shows too so!!
I'd recommend: - PreCure/Pretty Cure! All of the seasons are of a different set of characters with a different plot. They can be watched in any order. - Sailor Moon While there is the old 4kids dub, there's also a brand new dub! あなた can also choose between the original アニメ and the new Sailor Moon Crystal so that's always nice! - Shugo Chara It's really a fun show. It's got action and drama and comedy and romance and もっと見る and is really a good show!! Plus, it's not too heavy for kids. - Tokyo Mew Mew This was the 秒 アニメ I ever watched (unless あなた count the stuff I watched when I was little, but I didn't know what アニメ was then so). It's really a wonderful 表示する with likable characters and an interesting plot. - Ojamajo Doremi/Magical Doremi It's a cute 表示する about witches! It's aimed towards kids but really has some heavy stuff in later episodes tbh but it handles everything very well. - Nichijou A slice of life anime. あなた never really know what's coming 次 and it's super fun to watch! - Ouran High School Host Club Do I even need to explain this one? Great 表示する for people of any age 11/10 would watch again. - Squid Girl/Shinryaku Ika Musume A fun sci-fi/slice of life anime. - Free! My brother's first anime!! He doesn't watch アニメ that much but he really liked this one. It's a sports anime.
There are also Studio Ghibli 映画 out there if she would like to see those!
Remember, she might not get into it and that's ok! Don't try to force her if she ends up not liking anime!
It's an amazing idea introducing her to the awesome world of アニメ i would recommend these: -Sailor Moon - Skip Beat -Pokemon -Cardcaptor Sakura -Ojamajo Doremi ------I REALLY suggest the last one!!!-------
