WTC: Relentless Protagonist [SxS]

Story

The protagonist and Grendel Jinx are forced to work together to try and stop an enemy group from launching a devastating weapon, due to the machinations of Grendel's mother.

Unfortunately, the mission does not go to plan, and both the protagonist and Grendel find themselves trapped in the "Pleasant Grove Secondary School", where everyone believes they are transfer students.

After the initial shock, the pair gradually get to know their classmates, and things seem to be going well - at least for a short time.

However, it's not long before teachers and classmates alike are meeting violent ends. If neither the protagonist nor Grendel wants to become another casualty, a way out of their predicament is needed.

Will the protagonist and Grendel be able to solve the mystery ? Are the murders caused by invisible aliens called the 'Enemies Of Civilisation' or something more mundane ?
