This is a "game" that started due to "PGMOHC-728"; a campus murder, a group of people gathered, "Even if we are addicted to the deep sea, there will still be a beam of light calling you, giving you the courage to break through the pressure of the deep sea, and break through the sea level to embrace it."
Motto: Although life may not be as you wish sometimes, there will always be a reason for you to live.
