Ostracized and tormented by his peers to the point of breaking, Kazuhisa Kaya set off into the nearby forest atop the mountain with one purpose: to dig a pitfall and bring about the death of the person behind his suffering. However, right when Kazuhisa was about to succeed in his revenge, a sudden earthquake throws his plans out of whack! Caught unaware, all he can do is patiently lie in wait until someone lumbering across the path happens to fall into his trap. Kazuhisa’s excitement is short-lived, however, as the corpse at the bottom of his pitfall turns out not to be the bully he was expecting but a grotesque, pig-looking monster, and his confusion only grows as he’s suddenly greeted by a pure-white room and a RPG-like status screen.
Strange monsters now wandering the mountain and with newfound powers at his disposal, Kazuhisa is forced to throw all concerns over his tormentor to the wayside as he focuses on a new goal: survival. That’s not going to be as easy as it seems, however, as he’s not the only one to have been wrapped up in this mess…
The main female lead. She's calm and collected, and has a strong sense of caring towards her friends and others around her. She attends the middle school on the mountain alongside her best friend, Tamaki. Her first meeting with Kazuhisa is when he happens to rescue her from certain peril, and the two decide to join forces.
The not-so-lucky protagonist of the series. His highschool debut quickly spiraled downward after a certain incident and left him the punching bag for the entire school, resulting in a deep-rooted grudge against everyone there. He's quick-witted and cunning, and he's devised the perfect plan to "take care" of his bully, though things don't seem to go as planned...
Arisu's best friend. She's outgoing and playful, and rather athletic to boot. Her foreign features and well shaped figure give her an alluring appearance.
Certain circumstances lead to her and Arisu forming an unbreakable bond during their time at school, and the two are now inseparable. She's prepared to give it her all, even at the cost of her own well-being...
