This will be a spoiler free review after having read the entire manga.

Story - If you have read Love Hina you'll find the story of Gakuen Tengoku familiar. The problem is that the story here never really advance and in fact the manga seems unfinished.

There are a lot of stupid situations that make you ask "what's the problem with those people" and "does police exist in this manga?". Nothing really exciting happens and there are a lot of things that are not developed whatsoever. An example would be the principal who is the cousin of the MC and she likes him, but this part of the story is there just for basically 3 things to happen over the course of the manga.

The end is also very baaaaaaad.

The manga at least has a light atmosphere so that's a plus in my eyes.

The main character - This MC is the most useless character of all time. Seriously, he is so pathetic that it makes you angry with him. He is weak, dense, clueless, naive...the only thing he has going for him is the luck he gets for being the MC.

For the most part of the manga, he is never the one making things happen. He tries to resolve things, but most of time his ideas are dumb and often things get resolve without him doing much.

Overall - This manga could have been good, but without plot and with such stupid characters (most of the teachers and he MC) it makes it hard to call it good. The only thing i likde about this manga is the art which is good and the girls are all very cute.

I would not recommend this manga to anyone simply because there are much better options out there ready to be read and since time is something finite i advise you to go look for something better.
