Kids fighting to the death. One character is a full-blown textbook sociopath, another was sexually abused as a child, many others are mowed down like so much fodder.
Not so much "oh my God WHAT?!" as "Oh my God, adults are assholes". Basically like the manga version of Chicken Soup for the the Teen Soul: Tough Stuff
A lot of messed-up things implied and explicitly shown to the reader, from scientific experimentation; to torture; to pure sadism; to cannibalism; to slaughtering people; to cruel "games"; to rape and threats of rape; to piling up the drama and angst until it overflows.
Oh my God WHAT IS THAT.
What am I reading. What am I reading. Is this manga good? I can't freaking tell. It certainly is drawn in a very heavy-handed, sketchy way.
Bitches be very crazy. So freaking crazy.
People die a whole f*cking lot. People that don't deserve to die. People that do deserve to die. Meaningless deaths and almost pointless struggle for survival.
It's just grim, but not even the foreboding grim, just dark.
Ew ew ew ewe ew ew EW EW EWE EW EW EW FISH GET THE HELL AWAY EW EW EW EW EW EW!!
The art is a perfect fit for the story of a model/actress's downward spiral into maintaining her beauty at the cost of her mental, emotional, and physical health.
The definition of surreal.
Sexual sadism, sexual masochism, sexually aroused when killing people, really weird main character, and generally unlikeable characters trying to figure out the clusterfuck that they've gotten themselves into.
Bullying taken up to 11 and staying there to the point of soap opera levels.
