The manga is based on a high school student who is about to face the tomorrow of independance,he makes a wish that brings him in a world of joy at the start,but good things may not last long.
He and his friends face the cruel reality of this dreamy world...a place where the strongest survive.The manga is well written with a great variety of characters and some quiet cunning thinking,I really love it so far I am looking forward finishing it.Whoever looks into it and they are in for survival they are not going to regret it!
Although everything good has it's cons as well.There is not much character development overall or it might be predictable to see how they are going to change.The manga does not tire you but as a psychological-survival it contains some explicit content so I advise you to read it if you are mature enough *smiles*.
That was all from me have a good day!
