Nemuri no Fuchi, how do I even begin to describe this? The story is about these labyrinths that started appearing. These labyrinths are the reason for an increased cases of missing persons. Shuuhei Sazaka-san, our protagonist who's life was ruined due to a disappearance of his childhood friend, Kaori discovers the existence of these labyrinths. Like the edgy protagonist he is, he went there despite warnings of being extremely dangerous.
Fortunately, and despite how "extremely dangerous" this place is, he managed to escape. (Did you not expect that!?) Then there's the MIC whom are a highly suspicious organization claiming to be handling these labyrinth cases. Shuuhei gets accompanied by his bestfriend, Genji on the labyrinth after feeling guilty of abandoning Shuuhei once before for playing with a girl.
The story starts to get even more confusing with this mad scientist and his clones. Then there's the time travel introduced. You get it, this story is a clusterfuck of confusion. The concept - it's not that bad, kinda reminds me of the backrooms. But the writer seems to be inexperienced on how to write properly. I'd say nice try for trying to mix supernatural and sci-fi, although didn't turn out good.
