I just finished reading the series, brought to my attention by the random button. It is... weird. Is there a story? Yes. And like the other commenter said, it's a simple plot. But I don't like it. It could because how not-in-depth the characters were. It could because nothing was really realistic or immersive; like, I couldn't immerse myself in the story, not even a little bit. And yeah! There's a supernatural cause/reason but it's never mentioned how.
Anyways, don't waste your time. Yuri? Just shoujo-ai and book grabbing.
The plot was fairly simple-an near perfect school with (unneeded) shojou-ai peppered everywhere, a girl attempting to escape and finally does, place is never to be remembered, story ends with girl leaving a lasting memory.
The supernatural part though, was not explained.
How do the students not get their periods, or grow old in that place? Why does Tokarev want to build an all-girls sanctuary where no one grows old, and all of things, when girls attempt to escape, why are they killed? And most of all, how do they not maintain a certain connection with the outside world when they have truck deliveries and where on earth are the teachers? Many things are left unexplained, and I find the manga too short to be a proper perfect world/escape manga.
