You will seriously question the idea of fate, destiny, and the unfairness of the circumstances that every character (except the baddie) experienced in this manga. I was damn scared thinking about how the students felt in that school. If you had any similar experiences with school shootings and are hoping for a happy ending, please don't read this manga as it might trigger you.

But for those of you who enjoy reading about the darkness within the human mind and the lengths that one will do in order to fulfill any desire, please read this manga. This is a hidden gem

It's definitely a fun series at the start. It's like someone else said where you don't realize you're watching an anti-hero until you are like this teacher is straight-up irredeemable. It creates this nice pull and tug where you're not rooting for him at all but he keeps making these calculated schemes and getting away from them.

I think the series takes a nose dive once he has to go into panic mode and starts killing the students one by one. It's just not as interesting as seeing the cat and mouse game play out less gruesomely. Maybe rather it just is tooo long. I think if we saw him go into mass-murder like five chapters later we wouldn't have as much of the same repetitive type of they tried but he killed them dealies.

bruh this manga so intense and at first i dont think the mc is actually the antagonist, i thought that he is kind and nice teacher

I live in the same area as the location of one of the United States mass school shootings of the past 20 years. This manga... was well written enough that it mirrored an all to real set of events that has happened more times then it ever should. The main character and Antagonist of this story is a true to reality psychopath. No ability to emulate with his fellow humanity, smart, disrespectful of all human life and value unless it serves his amusement. Truly terrifying (despite many comments on readers saying this is not indeed horror)..

Trigger Warning: Do not read this manga if you are emotionally sensitive, have had family or have experienced a mass shooting in a school or public place. This manga was a reflection of all to real events and senseless loss of life. And I will spoil this because I genuinely believe this manga is a direct commentary on it. The monster wins in the end... due to a flawed system of justice and an all too real side of society. I am going to go hug my family and then maybe watch a nice sweet romance to try to escape. This manga felt too damned real. Love and Peace my friends.
