When Tarou Jimi is assigned as the homeroom teacher of class 1-A at an all girls' high school, the rest of the staff feel sorry for him. On the surface, class 1-A is full of pretty and talented girls on the cusp of adulthood. But under the pretense of grace and elegance, the girls of 1-A are akin to the spawn of the devil, known to drive all their homeroom teachers to resignation. Every teacher they have had has already been forced to quit with poorly disguised bullying and blatant blackmailing.

At the forefront of class 1-A is Momo Hananaka, a model who knows exactly how to use her charm to her advantage. As soon as she learns about Jimi, she gears up to make him regret being chosen as her newest homeroom teacher. However, Momo and the "monsters" of 1-A might be in for a surprise, as beneath Jimi's plain demeanor hides a dark past—a past that might make him nothing less of a monster himself.

Preliminary (15/? eps)
In short, a masterpiece in the unfortunately very niche psychological thriller genre.

One of the few mangas where actually every action makes sense from each characters viewpoint.
Additionally, the author manages to keep it interesting throughout and not slow down by fillers. He is just getting more extreme with every chapter as the students try harder and harder to get rid of the teacher.

With only 15 chapters out as of the time of writing this, it has already crafted a rich backstory with the darker aspects of human psychology at its core.
This certainly is not for the usual target-group of mangas and many will simply not ...

Mixed Feelings
Preliminary (33/? eps)
This sucks. This manga could've turned into something great but it didn't. The potential of a classroom full of sadistic girls could've been an actually good manga and I had high expectations, i was disappointed however.

The plot was fine, i liked it at the beginning but it quickly turned downhill from there. It was WAY too fast paced and it's plot twists just seemed like a quick hook to keep the reader from falling asleep. The main character didn't even seem like a main character considering the fact the whole manga was focused upon the SIDE characters. The manga was also a bit confusing, ...

Preliminary (29/? eps)
It's just a juvenile highschool drama, with a rather dumb plot and characters that are too edgy. Main characters are super cool and super pretty and super evil. Plot development is primitive and story's shortcomings are covered with harem-like scenes.
Storyline focuses on dreadful bullying and violence.

Started off rather well actually, with a teacher having to rein in a problematic class. That's a classic trope, but deteriorated into romance, bullying, nobody-understands-me cringe pretty quickly.

Recommended for enthusiasts of grim, edgy highschool dramas with pretty girls, that don't require you to think a lot.

Also, this is not a comedy. There were only a few gags early on.
