Coming into the show, you should know first off that this is an ecchi/harem/romance comedy with a sometimes serious aura to push the story along when necessary. If fanservice bothers you, Trinity Seven isn't for you, plain and simple. If that's part of the fun for you, then prepare to be along on a trip to Sexy Japanese Hogwarts.
Story: 7.5 (rounds down to 7, more on that later)
Continuing the Harry Potter analogy: MC Arata gets his life turned upside down when he finds out that there is INDEED magic in his world, and it's about to change his life... or at least introduce him to some beautiful new lady friends.
The first section feels a bit disjointed, but it's mostly about character building. From about the halfway point on, it's pretty easy to tell where the plot is going, but that's not to say you can't have fun on the way there. The pacing can be a bit inconsistent, but again, from the midpoint on, it stabilized.
Nothing groundbreaking here, a fairly simple setup of the oft seen "I must rescue the one i love", but with a couple of twists to keep it fresh.
Art: 7
There are a couple of moments I found really cool where they used real life photography with animation on top of it- had not seen that before. Otherwise, it just looks like your everyday normal anime. Character art is fine, and the action sequences are well animated, but nothing that will blow you away. (I compare things to Sword Art Online, which i find to be incredible well animated)
Sound: 7
The intro and four (count 'em) ending themes are all appropriately energetic and catchy. Not much to say here
Characters: 9
This is the meat of the show: the characters. You can't have a harem without breaking a few eggs, right? (woops, wrong idiom)
MC Arata isn't a blockhead moron. He knows what he wants, just not how to do it. He's also not afraid to get his hands dirty.
The titular Trinity Seven are a group of (all female) skilled mages who are cream of the crop in their particular area of study. They are varied, and fun, and definitely memorable. They aren't all introduced at once, so you get some time to know them before they all show up. I had no trouble remembering or telling them all apart, even though it felt like they introduced someone new every episode. The villains are varied, but I felt like they were rushed a little (in terms of development), but it is a 13 episode show, so not much time to work with.
They are all motivated in their own ways, and each one has a reason to be there besides checking off boxes in the harem trope *yawn*. Each member plays their part: they do it with style and a healthy dose of sexiness, or tsundere, your pick.
Enjoyment: 8
One of the absolute best parts of the show (for me, the only person whose opinion matters) was the 4th wall destroying humor. I love self aware comedy, and Trinity Seven delivers with a sledgehammer. Arata is also (from what i understand of harems, this is uncommon) an incorrigible pervert, and thrives in the intensely tense estrogen filled environment into which he's thrown (sometimes with the help of a friend). I never found that the show took the scandalous content too far- it never devolves into anything porn-like- strictly pg-13.
Final thoughts:
Fun anime, and after going back and reading the manga, it follows it INCREDIBLY closely, which I thought was excellent. Seven Days took a fun little product, added some extra polish and a bit of movement to the tv screen, and here we are. Looking forward to *hopefully* a second season.
