Erased from time again

Over in a small island that is cut off from the rest of the world, a school of students have to fen for themselves. There are no laws or drop backs or anything to stop them from doing whatever they want, tho they lived peaceful lives and no harm ever came to any of them. That was until the new recruitments arrived to the island. One by one they all started to disappear and die in a fatal crime, one boy was pined to figure everything out but, after he found the one he loved the most was gone forever he stopped at nothing to get back at whoever did it. Tho as the time went on he started to go mad unable to put two and two together.
