i came across this series as per The Animeman's video lol

but i actually enjoyed it! I'm a huge sucker for stories that take place in dark urban settings so this review might come off as being a bit biased.

Story: 10 (might containt some spoilers and is a bit confusing lmao)
Basically, (from my understanding) a selection of people have been abducted by aliens or something and have been placed in a fake version of Tokyo, where everything is monitored by an Eye. Anyone (except some special people) who talks about knowing the city is fake is going to be "killed", which means getting turned into a puppet for the aliens to control. however, there are also these people called "managers", "experts" and "specialist" who are like human commanders under the aliens. "managers" basically know everything and sell people out in exchange for their lost memories, or they can be promoted into "experts", and further into a "specialist". right now, there are 3 specialists in the fake city, and the key to escape the city lies within them. so, they have to be killed in order to obtain the key to escape. oh, and they all have regenerative abilities. so thats fun.

the story follows Makoto, Yukiko and Ruka as they try to uncover the secrets and figure out a way to escape the city. it jumps all around the place, from thriller, mystery, horror to some teeny tiny bit of romance (I'd say initially between Yukiko x Ai and Makoto x Ai, but the ship kinda goes towards Yukiko x Makoto later on).

Art: 10
oh the author is doing fanservice right god damn

like the art is clean asf no cap

Characters: 6
This is where the series' main flaw lies.
To be, the characters just aint cuttin it. My favorite character right now would be Tanisako because he just reminds me of Llyod from Spy X Family lol but he is extremely rutheless though.
The main problem I have would be with Makoto. He is just your generic, typical, self-insert MC in every anime or manga. He is like those "i believe friendship will overcome anything" type of guy. So you might need to get used to him. But one redeeming quality about him would be that he is not a dimwit and is quick to pick up things.
Yukiko started off pretty strong. I liked her character not only because of her design, but because of how cunning and sly she comes off as. She is like your drug dealer kinda guy. However, this slowly faded away, as she slowly becomes one of the "MC-kun please save me!" type of girl. But yeah I still like her cuz she has some good personality.
Ruka is the only good character out of the three. He is the smartest of the bunch and we actually get to see some character development of him, from a crazed maniac obsessed with Artificial Intelligence to a member who shows sympathy towards the other members of the group.

Now that I think of it, isn't Ai's name the same as AI? Coincedence?

Enjoyment: 10
I love the dark urban setting of the story.

And I love me some good personality.

10/10

Overall: 10
I don't want the character score to be holding this review back as it's only 25 chapters as of now. And I give overall scores based on my enjoyment score, so its a 10/10.
