@Cobaltasaurus Well, let's see.
This last season was all about the school love drama and the bad ass battles. So you had...
Gakusen Toshi Asterisk - About...as you may have guessed, this guy who can beat anyone and falls in love with the girl. The back story is that he's searching for his lost sister and there are schools that fight each other. It wasn't bad. Maybe 3/5.
Rakudai Kishi no Cavalry - This one is about a knights school that trains magic knights. Except there's this guy who can't use magic too well, so he just gets really good at using a sword and can expend tons of magical energy in a couple seconds. Also he gets the girl, a princess. It's get dark at the end, but it's more like a play time dark. It was okay.
Heavy Object - About wars between gundams..I mean objects, totally not gundams, and how an engineer and a marine are able to blow them up because we build them with obvious structural flaws. (Who the hell builds a boat out of a triangle!? WHO!?) They both get their girls.
Taimadou Gakuen 35 Shiken Shoutai - About a squad of exorcists at an academy that are the 35th test platoon, the worst one, who suddenly become the best one. This one was the best, he gets his harem. But no really, it wasn't bad, 4/5.
K Return of Kings - It's K. If you like K, you'll like Return of Kings, because Shiro is back, aww yeah. And more fighting, because it's K. 5/5. But if you don't like K and didn't watch the First K, then you'll give it a 2 of 5, because you won't know what the hell is going on.
Utawarerumono: Itsuwari no Kamen - Apparently there's another one of these things. It's the usual, time traveler, very confused, starts to lead a rebellion. Watch it if you like Utawarerumono, avoid if not.
Valkyrie Drive Mermaid - Holy fan service batman, but oh my god the best story you have ever seen. I know, you're thinking 'Alzie, that's like the most cliche shit ever' but holy shit is it true. It's awesome. Valkyrie Drive Mermaid hits home with its coming of age, do what you have to do to survive story.
Shinmai Maou no Testament - do you want to watch boobs and fighting? Then watch this. If not, skip it.
Sakurako-san no Ashimoto ni wa Shitai ga Umatteiru - This was surprisingly good. So an ornathologist starts hanging out with a kid after he gets a crush on her. It's pretty good. The story is deep, about how the woman lost her son and is projected onto the kid but the kid just wants her to love him and how they reconcile those feelings.
Owari no Seraph 2 - Did you watch one? No? Well don't watch this. If you did, watch this.
Noragami Aragoto - You can watch this independently of the past Noragami. It's a great show about a god that's attempting to become huge and his familiars including the girl he saved from death but in exchange she now has out of body experiences. It's cute and funny.
Lance N' Masques - Surprisingly not childish, about a guy who is trained to be a knight from birth. You will not want to watch this at the first 2 episodes, but stick with it and you will be rewarded with a surprisingly deep story about a boy struggling to overcome the expectations society puts on him due to the position his father once held when all he wants to do is protect a girl.
Hidan No Aria AA - Did you like Hidan No Aria? More importantly, did you like Aria enough to watch an entire 12 episodes dedicated to her fan girl? Watch this. Otherwise you won't get it and won't like it.
This season you have:
Active Raid - All I need to know about this is that they wear exoskeletons (So gundams, but we can't call them that) and attack things in a post-apocalyptic tokyo.
Akagami no Shirayuki 2 - Season 2 of Japanese Cinderella. Yep Yep.
Ao no Kanata - A kid wants to join the flying circus. I don't even know why i'm listing this, but it's by Gonzo so i don't think it'll be terrible.
Boku Dake ga inai machi - So this manga artist gets sent back in time to prevent deaths.
Bubuki Buranki - Kids with sentient weapons fight crime in tokyo and beyond
Dagashi Kashi - Father must convince daughter to bake chocolate not make manga
Dimension W - Watch out, the repo man is coming for your supernatural weapons
Divine Gate - Typical everyone gets superpowers and now shit isn't right anime. Basically K with a different feel.
Durarara - yep, there's another one
Fairy Tail Zero - MORE FAIRY TAIL
Gate Second Season - [heavy breathing intensifies]
Hai to Gensou no Grimgar - Supposed to be kind of like Gantz but not as bloody apparently. I'm not sure where this is going, but gantz is your guideline.
Haruchika - If you know what these novels are and ever wanted an anime of them, congrats.
Musaigen no Phantom World - So school children fight phantoms which are manifestations of our doubts and fears.
