The ground of Japan trembles!! A high-tension disaster comic begins!! "The world might as well just turn upside down," thinks Motizane, a salaryman who despite his earnest dedication to his job, spends his days being belittled by juniors from other departments and struggling to keep up with an endless mountain of work. In the midst of these exhausting days, Motizane makes a mistake at work and is forced to head to Gotenba City at the foot of Mount Fuji with his boss. Just as he reaches his breaking point and decides to quit his company, something unthinkable happens...! Yuu Sakado, the creator known for "Ushijima the Loan Shark Gaiden: Nikumashi Densetsu" and "Asyl," depicts a "power" that is both overwhelmingly strong and utterly merciless.
