Mashiro Ichijou, an attractive and popular high school student, has always lived his life as a boy. However, nobody notices that deep down, he resents the fact that his body is half female. He has decided to conceal his femininity from those around him, while in reality, he is insecure about who he is supposed to be.

One day, an unfamiliar nurse asks Mashiro to follow her to the school's infirmary in the basement—an office that has never existed until now. Little does he realize that the moment he steps into the mysterious room, he will never be capable of returning to being the person he was before.

As he struggles to find his true identity, Mashiro must face the disquiet in his own heart, all while protecting himself from the prying eyes of his classmates. Slowly but steadily, the unbecoming truth of the world is laid bare: all its lies and deceit engulfed in nightmares that only unfold in broad daylight.

[Written by MAL Rewrite]

I don’t often read shoujo manga, mostly because I tend to find that shoujo manga would fall under one of the two categories: ones filled with blushing heroines, princely (lady) boys and convenient fairytale stories or the other side of shoujo; the one that attempts to be dark and mysterious but most of the time only ends up being filled with pretty gothic clothes and whiny characters. Although there are some excellent works that fit under these stereotypes and pull it off, I do get rather bored of its predictability.

After School Nightmare is such a shoujo manga that keeps me on my toes ...

Mixed Feelings
A (highly) unique manga but not deserving the amount of high reviews it has on MAL.

The thing that stands out to me is how far off the reviews are with the actual "overall" definition of the manga.

This can be understandable as it can be quite difficult reviewing a manga with several major character developments without spoiling the whole thing.

This however doesn't excuse how all the reviews read like they are reviewing the synopsis instead of the whole thing.

The two main issues I'd like to contrast with the other reviews are that:

It's been a few years since I read this manga and I still mentally groan when I think about it.

It felt so very shallow and even insulting at times with how it handled gender, sexual orientation, etc. Which I will give it that it is from the early 2000's so things hadn't progressed to where they are now. Regardless, I don't think the characters were handled well and the whole read left a bad taste in my mouth.

If none of this bothers you then you will probably enjoy the read. I would just caution anyone who might find the handling of the gender ...
