The story/plot premise of this series, was at best all over the place. The first 3 introductory episodes weren't very good to an enjoyment level, the first episode was a bit cringe worthy, and unfortunately doesn't really establish anything but set up the tropes and show you how the harem starts.
The story of this series is about a "mysterious" I guess you could say temporary substitute teacher named Glenn Radars who's background becomes more apparent when flashed back later in the series, and the whole show revolves around him and his "class" but more like 3 girls, Sistine, Re:L, and Rumia.
The reason I say "class" is because throughout the show the class in generally doesn't really matter at all besides certain students. The class is more of a "support when needed for Glenn" and not a "fundamental" part of the show.
One thing that I hated about this show story/plot wise lies with the Title and nonstop hearing of "AKASHIC RECORDS" its in the TITLE, and literally said god knows how many times in the show, but never gives a single thought or minute as to explaining what even IS the Akashic Records. Instead the whole plot revolves around rescuing Rumia and other girls the entire series like you're a knight saving the princess from the tallest tower trope in fairy tales.
The story side I rate a 5 because the Akashic Records which is never talked about once in the whole story, and constant use of repetitive tropes, and cliched bullshit throughout the show made it very very boring, and on the contrary it being rushed to all hell is very nice also.
Character wise I've already gone into for the most part, and the characters around Glenn are all just... bland. They're really really boring. We have typical tsundere Sistine, typical loli Re:L, and your basic anime girl Rumia.
Something I also don't understand though as an Academy why is it never seem frowned upon the entire series that there are students constantly trying to get with Glenn? I fail to understand that as we clearly see other teachers/faculty see how the relationship is etc. I mean, there should be a boundary usually, however that is obviously not the case in this show.
On the contrary the enemies/villains in Akashic Records are even worse, not only do they all do the same stupid idea: LETS GO CAPTURE -insert whoever here- for their magic power, its done so almost Team Rocket like where there's never any success rate. The funny part is the amount of stupidity into some of the things that happen in the series. Not recommending this, but go rewatch some of the episodes Glenn uses the fools world and realize the laws of the card get broken whenever they need to keep the sequence going to work out how the author wants it to, and not "what actually makes logical sense."
Art wise, you can kinda tell by how they dress all the female students like they're complete skanks, and the males all have the typical uniform seen in any other LN adapted magic/school/fantasy harem series dresses, so the art really isn't anything you haven't seen, and the animation also wasn't really different compared to anything else.
The sound from the anime besides the OP was just meh. I actually really do like the opening theme for Akashic Records, but the voice actors do at least fit their respected character for the most part, but most of the time when something serious/emotional was happening it was poor.
My overall enjoyment of this series was weird, it started off like "wow this looks like its gonna be complete garbage." to "eh, maybe this can make a comeback?" and then back to "man this wasn't anything I haven't seen already." by episode 12. I give it a 6 being fair because honestly as a harem anime standpoint it really isn't that bad, but it isn't amazing either.
Overall, I'd say if you like harem series and never get sick of them, go ahead and watch this show. Its a show where you kinda just shut your brain off to enjoy. I personally didn't really like the show due to the fact that it breaks its own rules, pretty bad cast overall, and just the fact the most important parts of the actual show were never talked about in the slightest. I would really only recommend watching this if you want to kill time, or just really really like harems. I rate it a 7 overall, its not like its bad, or mediocre, I'd say its good for the most part for a harem genre show, which I generally rate it as just good or poor as is lol.
