When Rising Blood was built, it was during difficult times. Every race had been at war either with, or against, one another and was risking extinction, but the creation of Rising Blood ended the threat. Why? Because it wasn't just a school. It was a home, a fighting cause, a battle ground...and it encouraged the younger generations to fight for one another. The school eventually was able to unite the races and strike a peace treaty...but ten years later, it was burned to the ground in an act of defiance. Naturally, chaos followed suit. Distrust of one another rippled through all the races, because the burning of the school symbolized an ending of their peace treaty. The wars following were worse the second time around. Angels and demons destroyed one another, extinquished their respective races entirely. In hopes that rebuilding the school will unite everyone once more, former students Cho Kyuhyun and Kim Jonghyun followed in their mentor's footsteps...but only time will tell if they succeeded or not.
