Prologue

"The Lord has decided that you will continue to stay on Earth… And he has decided to bestow you the position of a Guardian." Allen smiled at his dark-haired lover.

"What does a Guardian do?" His lover leaned forward to steal a kiss from him.

"Protect mankind against demons." Allen smiled at him.

It had been 900 years since Kanda had been made a Guardian. And 400 years since Allen had left him. At first, they had been happy, living together and moving from place to place to avoid attention from the humans when they looked too young to be what they claimed their age was on their records. Life had been good and they dealt with any signs of demon summoning rituals or sacrificial rituals they came across. The demons had been increasing in power when humans sacrificed something to them and once in a while, they had to deal with a demon possessing a human body.

Even though they lived happily, Kanda had noticed that with each demon exorcism Allen carried out (he was the only one who could do it since he was part of an angel), Allen became weaker. And towards the last 100 years before his disappearance, Allen had had often come down with some sickness, be it a common cold or stomach flu.

And then, one day, Allen was at home, recuperating from another illness and Kanda had left to stop another demonic ritual from taking place, Tyki had appeared and warned him that there were more signs of demon activity emanating from Hell and that Allen needed to return with him to Heaven so that Neah could do something about it. And these demonic activities involved one particular demon.

Beelzebub.

Kanda had led him back home, but instead of the small cottage they had been staying in…

Everything had been torn apart. The gate was in shambles and the walls of the cottage were torn, deep gashes embedded in it. Kanda had rushed into the cottage with Tyki, dread tightening his chest. And when he stepped into the room…

Blood decorated it. Blood pooled on the floor, splashed carelessly across the ceiling and painted every inch of the room red. And in the middle of the slaughter was Allen Walker. His pale skin standing out against the sickening red of the room. His grey eyes were blank and he stared up at the ceiling, an expression of horror transfixed upon his face.

Kanda couldn't believe it. He stepped forward and his boot sunk into a puddle of fresh blood with a sickening squelch. He turned to one side and was violently sick.

"Kanda…" Tyki's voice called to him. Kanda looked to him weakly. The angel pointed a shaking finger to the paper lying on Allen's chest and Kanda read it silently. His blood froze and his heart nearly stopped. On the innocent piece of paper were four words.

"It was Kanda Yuu…"
