Those infected lose all bodily functions and may even fall into a vegetative state. These victims are reported to the public as deaths by unknown causes. To protect humanity, hunters called "Debuggers" fight in the shadows to defeat them. A Debugger's weapon is transformed from a cherished everyday object.
And Guest was one of those Debuggers.
Guest is an ordinary high school student, but his existence as a Debugger must not be known. If discovered, he must perform a "Memory Debug" at his discretion for the safety of all Debuggers. The rollback is completed by placing a hand on the target's head and chanting the command.
