1. Sailor Moon ~ I suppose the fairy tale aspect of the show has a lot to do with it. It was the first anime I'd seen, so it has that in its favor, too.
2. YuYu Hakusho
3. My Hero Academia ~ My energy about the show has diminished a little, probably from waiting so long for the story to progress, but I still like it (and I still love the first two seasons in particular). Admittedly, Bakugou is my favorite thing about the show, there's a lot of nuance there and I love the character's design / the voice acting. I enjoy the show most when it accentuates the whole of class 1A.
4. Fairy Tail ~ The show is admittedly very fanservice-heavy and sort of cookie cutter anime in some ways, but, I don't know, I like almost the full cast of characters. Natsu, Usagi, Yusuke, and Tanjiro are probably my favorite anime protagonists. I feel like this show centers around friendship similar to the way Kingdom Hearts does--but it does it much better than KH has managed, imo.
5. Soul Eater ~ I love this, partly because you so rarely see great female chessmaster-type villains like Medusa in anime (or good female protagonists like Maka either for that matter). Crona is adorable and Soul / Maka are a great central relationship on top of it all. I do find Black*Star annoying, but he doesn't ruin it or anything. I hope they one day make another anime with the complete story.
6. Demon Slayer: Kimetsu no Yaiba ~ The series has *gorgeous* animation... And Tanjiro is a great protagonist. I've loved the voice acting for the main three male characters.
7. Tenchi Universe / Muyo ~ Pretty much the ones where Ryoko is the endgame. (I hate Ayeka.) Muyo has the best animation, but I'm generally more attached to Universe. The ending with "Dimension of Love" in particular gives me nostalgia.
8. Bleach ~ I haven't seen all of this one--I have seen around 70% of it though. I guess I would've made more of an effort to finish the rest of it if the full manga had been adapted, but knowing it doesn't end in full sort of killed my buzz. I really enjoy it though.
9. Digimon Adventure / tri. / Kizuna ~ I don't really have any use for the other seasons / spinoffs besides those original characters.
10. Inuyasha ~ This show is very repetitive thanks to so much filler, which is why I almost put Outlaw Star here instead, but I do enjoy the characters a great deal in the story-centric episodes. I always hated revived!Kikyo and Miroku though.
I've recently been trying to watch some of One Piece. There are just so many episodes..... When I first started Fairy Tail a couple of years back, I though it would take me forever to see it all, but One Piece is like 5X longer.
