The Pun Tyrant
No worries there. I do keep it in my signature for a reason XD Even though not a lot of people come here...I know this post is literally a year old, but I’d like some recommendations.
1. It doesn’t matter much to me, as long as there’s at least 12+ episodes already out.
2. I have a deep love for romance, shoujo, shounen, school, sci fi, horror/psychological horror, comedy, slice of life, and reverse harems (but having one or more of those traits not in it is fine). I dislike harems, ecchi (although light or moderate fan service is okay, just don’t go High School of the Dead on me. . .), and some historical. Anything else is fine and I don’t care too much if it’s in or not.
3. I’d prefer there’s a manga if the ending isn’t really clear, like in Kaichou wa Maid Sama. Also, just for good measure, here’s a list of anime I have seen.
Sword Art Online, Sword Art Online Alternative: Gun Gale Online, Fairy Tail, Psycho Pass, Mirai Nikki, Fullmetal Alchemist, and Fullmetal Alchemist Brotherhood, Kiss him not me, Kaichou wa Maid-Sama, Boku no Hero Academia, One Piece, The “Fate” series, Highschool of the Dead, Boku no Pico (uggh I regret watching it), Attack on Titian, One Punch Man, Re: Zero, Himouto! Umaru-Chan, Luky Star, Tokyo Ghoul, Black Butler, Soul Eater, Vampire Knight, Kakegurui, Free!, Yuri on Ice, and Shokugeki no Souma/Food Wars. (Hope That narrowed down the possible list)
Star Recommendations (in no particular order):
*Gosick - Picture Sherlock Holmes as a loli, boom Gosick. Surprising no one this anime has a good deal of Victorian inspiration, with romantic leaning and a hint at the school genre too, though it's more context than anything meaningful. It also has slice of life, shoujo elements and a degree of horror (I think) due to the mysteries.
*Mahoutsukai no Yome - 20 something episodes I think, at some point I stopped watching it, but I'll let you know part of that was because I was fed up with just how much praise this show was getting. Put in the simplest way I can, there is this girl who sells herself as a slave and is bought by a benevolent magician who treats her well but wants her to become his wife. I know it sounds very creepy, but it's not as creepy as it sounds in the actual narrative....probably. It's one of those "the prince kissed a girl in her sleep, but that was sleeping beauty" type of situations.
Anyway, it's a heavily romance-based show with a good deal of shoujo elements and even a degree of reverse harem stuff depending on how you look at it. I can't quite tell you wat era the actual world is supposed to be on, but for fans of history and especially of mythology, the weaving of folklore into the worldbuilding is jaw-dropping as is the art and musical score.
*Angel Beats - Appearantly when you die, you go to highschool. Well, there is a lot of mystery in Angel Beat's actual overall story, but a good chunk of it is kept to the end so I won't spoil. However, it contains an absolutely fantastic mix of comedy, slice of life, highschool, action, a degree of horror and it is often renowned for it's drama too. It does have a strong romantic pair developed over time as well.
*Assassination Classroom - The teacher of a class for failures turns out to have just blow up the moon and is now threatening to do the same to Earth unless they let him take the position of teacher in that classroom. The students are tasked with murdering the living sh*t out of that mach-speed-moving-monster. Over it's two seasons assassination classroom remains a phenomenal anime even on rewatch, juggling an impressive amount of characters and tones, and developing every single one of it's aspects. It's got action, comedy, drama and as the title implies it's set in a school (well, it's a middleschool rather than highschool but eh...)
*Inuyashiki - stylistic and one of the only 3D anime I ever managed to bear watching, this show focuses around an old man (heartbreaking first few scenes, caution advised) who gets accidentally smashed by an alien ship and they reconstruct his body using their own technology. Not much in the way of romance, but the horror elements, scifi elements and action are pretty high up there.
*Mahou Shoujo Lyrical Nanoha (series) - Some magical girl shows take the best of shounen and mash into a shoujo version, and Lyrical Nanoha is certainly one of them. There are...questionable romantic elements, namely in later seasons where the two leads arguably become a lesbian couple, though at first you can expect plenty of great action with a good mix of humor and believe it or not pretty amazing scifi (well, to be more precise it's science fantasy, so I guess it depends on whether you consider star wars scifi).
*Planetarian: Chiisana Hoshi no Yume - Now this one is a little out of your rules, simply because it is finished but it's only a 5 episode show. Nonetheless it's an absolutely astonishing and beautiful anime, more like a brilliantly composed movie than a single running series you could say. Rather than give you a synopsis, I think this one is an experience one ought to savor rather than go prepared beforehand, so I recommend watching the first episode and decide whether you want to continue from there or not.
*Kotoura-san - Brilliant first episode which made me make a whole two part post just detailing it's brilliance, this show is about a girl born with the ability to read minds. The way it explores her life and the consequences of having such a power in a world where no one else does or believes it would exist is done in a way very few shows can brag of doing. Highschool, a bit of drama, quesitonable horror, and pretty great romance.
