Silence filled the surroundings as both Eliana and Greg watched Kuragari giving his life force to Zane.
Zane's complexion was akin to a zombie; pale skin, trembling limbs, blood flowing out from his nose and mouth while his breathing was extremely slow. If it weren't for the fact his chest rose and fell from time to time he would have believed he was dead long ago.
"Just what the hell happened here?" asked himself Greg, as he watched Zane's dire condition before him.
"It seems he used a Taboo Art several times and it backlashed on him quite sorely," explained Alice inside Greg's head in an indifferent tone of voice.
"What kind of Taboo Art?" asked Greg.
"It is called Soul Sacrifice. Exchange for your life force you can summon your Guardian out in its fullest potential for a limited time. The longer is the time limit the harsher the requirements will be."
