*sigh* This was actually pretty good despite being made for a teenage boy/young man. Good old male gaze.

Here, let me give you just one example:
Female student: "So what kind of girls do you like?"
Main character (male student): "Busty ones."

There you have it. I should have expected this from the cover and the mature content sticker.

But at least the plot was good. And it was funny.

Trinity Seven, Vol. 1 (My Kindle Review)

MY 250TH BOOK READ IN 2022!

In this manga, it follows Arata Kasuga who happens to be a shameless pervert who always says what’s on his mind. An unforeseen event happens in the form of a “breakdown phenomenon” that causes his cousin and their hometown to vanish. With the help of Lilith, a stern and pure teacher of magic, Arata enrolls in the magical Royal Biblia Academy in an attempt to learn magic skills and get his cousin back. In the meantime, he’s spending his time perving around Lilith and a group of girls who have special powers and he’ll soon learn he may have surprising powers.

I wasn’t really expecting much from “T7” given how it seemed like other manga I’ve recently read, and I’m kinda glad. The fantasy plot and world feels a bit typical and there’s not much explanation about it. Arata’s definitely your average anime perv who, for now, isn’t really that likable since he’s more focused on the girls than how his life changed. It’s the humor and Lilith’s reactions that pretty much keeps it all alive and the girls’ scattered personalities bringing surprises. An OK fantasy manga that’s more on humor than spells. B (75%/Good)

Trinity Seven is a typical Japanese style fantasy manga. It has all of the hallmarks of such a story. This includes the fan service, the domineering guy (who is also lecherous, by the by), the girls who just need to be shown kindness, the tsundere girls that abuse him, so on.

Of course, the guy, Arata (our main male protagonist) is really powerful. But in this case, so are the girls. It isn't that this never happens in such stories, but usually the powers of the ladies aren't focused on as much. The girls here are, in some ways more powerful than Arata, starting with Lillith-Sensei.

The story starts when Arata notices strange things happening, like his cousin/childhood friend acting strangely and the sun being black. He pushes the issue and finds out that the area he lives in is no longer around. It was subjected to something called a "breakdown phenomenon". This occurs when magic goes out of control and the surrounding area is destroyed. Apparently, this happened in Arata's town and he recreated it through (unknowing?) possession of a special magical grimoire.

Unfortunately, this could cause future disastrous problems, so Lilkith (who tracked him down when investigating the breakdown phenomenon) gives Arata the choice to have his memory erased or be killed. But when he finds out his cousin, Hijiri, still lives and could be restored, he rejects this and asks to be trained at the magical academy where she teaches instead. This way, he can eventually bring Hijiri back.

The story is fun, and quite humorous. It us somewhat sexist in the "women are emotive, men logical" department. Though this is only a plot point to explain why the most oowerful mages - other than (the impulsive, emotive Arata - are women. And the "toilet humor" might bother some, but it is relatively minor, to be fair. The art is detailed and good, this being a big fan-servicey series and all. Characterization, other than Arata being a major siscon, Lillith a lonely and uptight teenage prodigy, and some other characters being mischievous or weird, is not big. Of course, this is the first volume.

I quite enjoyed and recommend this.

This is turning out to be one of my favorite series to read in awhile. I actually came across this by watching the first episode of the anime and wanted a taste of what it had to offer. In short, I was blown away. Although it has the typical setup of a main protagonist going into an unknown world by accident, the story supplements it by the characters it introduces. The characters have well defined personalities that differentiate them from one another and I enjoy it. I honestly can't find one character I really dislike. It also helps that the main protagonist is not a giant blockhead like most harem leads [I'M LOOKING AT YOU INFINITE STRATOS AND TO LOVE RU!!!] Overall, I would give this series a read with interesting setup in magic, defined characters, and stylized art. This is one series I am glad to put in my shelf

I got this blinded, I just got it because it was on sale. Turned out to be a good one very interesting. The beginning did kind of mind fucked me with what was going on but as it kept on going I got it. The whole magic school is pretty cool, the test they did on him in the room with the other girls was pretty good. Story so far has my attention. I will be buying the next issue as soon as I am done with other books or it is on sale. I do recommend it if this is your kind of genre.

Three stars only because of the fanservice that makes this rated M. The story and characters are quite interesting.

I love this series, it's quite good; it has lots of fanservice and ecchi in the story...yes but it makes the story more enjoyable and hilarious. Plus the plot is great and all the characters have their own uniqueness to them and the way they portray the magic and the system, and the tests are great. The storyline in a way is original, the magic and high school thing is common...yes but it has it's very own plot that sets it apart from other; ecchi, magic, high school, comedy manga or novels. The characters are also unique and the protagonist is quite powerful, but the other characters aren't weak like other manga or novels. And all the characters play a role equally in a way and help further advance the story. At the time of this rating I already read the entire series and watched the anime also. i would recommend this to almost anyone honestly, its great if you want a good laugh, some m rated ecchi scenes, great battles, even mystery, the magic concept of this book is amazing, and the fight are nicely illustrated also. I generally enjoyed this book.

Another of my brother’s recommendations. Fortunately, this has an interesting story to tell, though I do have to ignore the fact that there are random ecchi scenes and big breasts for absolutely no reason at all (hey, we all know that men don’t know how to write female characters but what’s new?).

Anyway, in this first volume we are introduced to a bunch of characters that are studying in what seems to be a school for magic users. The MC has enough power to own a grimoire, therefore he must be watched before he causes trouble.

Now, I know this has an anime adaptation but I refuse to watch it until I’m far ahead in the manga. I do plan to continue with the series ‘cause it is interesting enough for me to pick it up. Hopefully in the next volume the plot and the magic system have more relevance than the harem who fall for one helpless guy.

Off to a good start. This is rather interesting.

So, a sexy, pervy, end-of-the-world, magic boarding school slice-of-life story is what we have here. Definitely different. Gorgeous girls, to be sure. Did anyone else think the head of the school was actually a woman? Or just me? It wasn't until the incinerator scene that it made clear that he's a he, so the headmaster. Anyhow, I liked what I've read so far, so I'm jumping right into volume 2 as soon as I'm done here. Art, pretty darn good. Pleasing to the eyes, and very detailed (I always love the background details, shows the artist's true talent). Dialogue, great. Pretty funny at times, silly & urbane at others. Firs well. Characters, likeable, interesting, intriguing, exciting, fascinating, & in the case of most of the girls, totally adorable. A few girls are downright creepy.

Después de ángeles voluptuosas y chicas monstruo ahora toca leer de brujas que controlan 7 elementos basados en grimorios antiguos que contienen además los 7 pecados capitales.

Debo decir que este primer tomo, estuvo muy entretenido y la trama se me hace muy extraordinaria. Sin embargo, los chistes o las situaciones cómicas se me hicieron muy forzadas y ni una sonrisa me sacaron. tal vez sea por que estoy en un momento muy dificil y por eso no quiero sonreír.

Aún así, seguiré leyendo esta historia, para ver como se resuelve este gran conflicto mágico y dimensional.

I'm still trying to figure out why this has an M rating. It has some fan service, but not nearly enough to justify the rating. The story while interesting just didn't grab me. Some parts just don't make sense and I'm wondering if the story (and fan service) were toned down for western audiences. The female characters all seem interchangeable and the MC is funny, but I don't know if it's enough for me to continue with the series.

An enjoyable read, but certainly not a classic. The magic system is confusing, poorly explained, and feels inconsistent. I did appreciate that they're up front about the fan service, at least, rather than being apologetic or in denial. If you want a typical "normal boy in magical world" story with more T&A, this may be the title for you!

Really appreciate the world and atmosphere. Areta is a pretty solid protagonist and the humor and action all come together to make something special. The only thing I didnt like was at some points the dialogue felt choppy but as the volumes and story progresses it'll probably get better and better.

Locura en este arranque de serie. Con un premisa compleja de entender en principio, nos presentan una academia de magia, repleta de mujeres, y un protagonista con un gran poder oculto y con un toque picarón importante.

This manga has some silly humor and the story is starting to build nicely. Character development is a little lacking but overall its interesting so far.

I will admit i love the show better than the manga but it’s still the same concept. Lilith is hot as always.

First I will say that if you don't care for fan service or a slightly perverted main character, I would stay away from this one. However, the story is starting to get interesting, plenty of questions that need answering, main character is overpowered which is always fun in a good manga, and the idea of a school of mages is always welcome in my book. Will probably read more to see how they develop the story.

Bon, par où commencer ? Déjà c'est un manga harem ecchi, donc un genre particulier.
L'histoire est prometteuse, les concepts qui commencent à être développés sont intéressants et augurent du meilleur. J'ai par contre eu du mal avec la narration, très peu naturelle... J'espère que ce n'était le cas que parce qu'il s'agit du tome introductif, et que la suite est moins bizarrement et maladroitement racontée.

I was hoping the artwork would be better then it was as the story progressed. Unfortunately, it doesn't. If the writing was stronger I'd give the art a pass, but with the story switching from semi- serious to making fun of itself I couldn't latch onto the plot. I'll give it another volume and hope something improves.

The world building for this book severely lacking. Characters are way over the top. Sexual assault is treated with a wink. I bought two more volumes (because they were on sale), so I'll probably read them to get a sense where this series is going, but if they just continue what was started here, I'll give up.

Oh just simply NOT! The premise was good but the dialogues are just nonsense, plain and simply stupid. A lot of the situations aren’t justified and happen just because. I will have to get rid of this. I don’t want it in my collection.

Good art story is confusing.

Can't seem to follow the storyline. The characters all seem to talk about something that never becomes clear. Maybe the next volume would bring answers but it seems a confused mess. The art is very nice and the main reason for the 4 star review.

I'm mystified! How did this series get to 20 volumes? Volume 1 has almost no story and the fan service isn't even that good. I have the first 12 volumes, so I'll keep going for a while, but if things don't improve, I'll waste only money, not time as well.

Sometimes you wonder about ecchi for ecchi's sake.
I mean, the cover should have tipped you off that there was no story here...just good ol' T&A from underage girls! Never change Japan!
