Uchida is a high school student genius who created a device that is supposed to make people have good dreams but he always had bad dreams when he tried it on himself. One day, he caught the school doctor sleeping at the clinic and decided to try the device on her. It turned out that it works surprisingly well on her and that she wanted to buy the device from him. He then tries it on his classmates and it became quite popular with the rest of the class as people start lining up to borrow it. Meanwhile, there is growing concern that users of the device are starting to have difficulties differentiating dreams from reality.

Pretty crazy...

I can't really put my thoughts into words, but I sort of like it, but at the same time I don't. Reason why is that there are some parts of the manga that I do not enjoy. Though it is interesting and the plot is some what new and refreshing. Though from what I see in the first two volumes things are going to get gruesome, nasty, and horribly wrong.

Misinformation about volume 2

@BowlOfNoodles and RS456,

With a manga like this, of which the main theme is the blurring line between reality and dreams, its easy to misinterpret something that happens because of the ambiguous way it's presented sometimes. ESPECIALLY if you're only looking at the raws, which is what I'm definitely going to be avoiding for a series like this.

Spoilers for volume 2:
Spoiler (mouse over to view)
Uchida's childhood friend and love interest does NOT get raped. The rape that's shown is a dream of a guy that's obsessed with Akari. As for the teacher and her gangbang fantasies, the most recent developments make it intentionally ambiguous whether she's engaging in these acts in her dreams or in reality.

It's certainly still a bit difficult to read, but it's clear that this isn't a manga that's going to be all sunshine and roses. The subject matter lends itself to some dark and psychological ideas that I'm sure the mangaka will be exploring in later volumes. That having been said, the plot is surprisingly engaging for a borderline-H manga and the characters have a good amount depth for this type of story. And speaking of blurring lines, be warned: this is about as close as you can get to actual hentai. Be prepared for graphic sex scenes.

Very Mentally Draining

Some of volume 2 just came and and I gotta said this is quite mentally draining for me. It started off pretty good, the concept is good of everything is from dreams, but volume 2 takes a turn.

Spoiler (mouse over to view)
There are lots of implications of rape and gang bangs in volume 2, as of right now not much information is given, but given how the characters are reacting, chances things that are happening are reality and not the dream. I really like the concept, but I can't get over rape and gang bangs(even if the women allows it), just not my cup of tea. Which is why it's mentally draining for me. I'm not dropping this yet, but would like to see what happens in the next volume, hoping Cuvie doesn't make me regret reading this.

Hoping for a good ending for the MC! Always Hoping for a harem ending for the MC!

From vol 2 from the looks of it it is getting bad.

I think Uchida's childhood friend gets raped and became a rape victim. From the looks of it the glasses girl is pulling the string so she can get Uchida

I admit the first 2-3 chapters are just pure hentai fluff. The plot is paper thin and characters come and go, but in later chapters you'll find out that all those characters serve a purpose in the overall story.

As the story continues, scenes from the nightmares start to blend into reality. It's hard to tell even for the reader what is real and what is not. Cuvie's art is beautiful as always, the sex scenes don't feel unnecessary, and the story is really intriguing.

spare me who don't have access to the raw, i see the 2 scanlated chapter incredibly mediocre hentai. as i don't enjoy reading mindless manga (especially hentai), i find this title simply boring. comments tell me there will be nice development after two volumes, but since its still far away, i will put this on hold.

best borderline h-manga with mind break

at first i wasnt really sure if it was going to be a good story, but after reading the 1st and 2nd volume i gotta say that is really good. the way the author plays with the mind of the reader, i feel like its really altering my mind i i find it extremely fascinating how weak the human mind is. cant wait to see volume 3, and hopefully someone will decide to scanlate this series. I believe this is the best psychological manga out there. The author, she's a genius

Horror, Psychological?   
Rating: 8.0 / 10.0

This manga is mentally and psychologicaly horrifying! The main protagonist obviously until the 2 volume does not see the danger he has created and is also very unresponcible till the 2nd volume. Like video games how they impact our life one way or another (not saying that we do what we see), but his invention of granting people the dream they wanted impacts their life but in greater terms, in which they have trouble differentiating reality and fantasy. This eventually leads to many horrofic crimes and forceful events.

This manga really do give me the shivers, and to a degree it really is a horror and the psychological tag should be added.
