He was dressed in a dirty, creased old coat, and the stubble on his chin said he hadn’t shaved in days. If judging by appearances alone, this man looked even more like a drunkard in a pub than Byakuya, who was inside his own house and dressed in everyday clothing. However, his eyes refuted all that. The temperature in that man’s eyes had already surpassed the realms of cruelty or mercilessness. It was only filled with the cold sadism and lethality of a wounded beast. After staring into those eyes, Byakuya surrendered all will to uncover the origins of this man or his business here and became a complete slave of despair.

Who this man was, how he had broken through the impressive layers of protective boundaries outside the house; none of that mattered now. This thing that now appeared before Byakuya was undoubtedly the reincarnation of the very horror that he had only managed to temporarily forget through the effects of alcohol for the past week.

“…Where is Irisviel right now?”

Byakuya was convinced that he must answer before he understood the meaning of the question, or else he would be killed.
