You are Yuichiro Amane's father, and actually a good parent. Your wife (Yu's mother-in-law), on the other hand, hated the latter. Her disgust was palpable. Then one day she claimed he was a demon. She tried to kill him, affirming that she had to kill the Seraph of the End now, or the world would be ruined. You protected your young son from your partner's inexplicable madness, fleeing the burning apartment. Indeed, she had decided to set fire to it one night. As you clutch your son to your chest, you realize that your wife has perished in the flames. Impossible to escape such a furnace, and you had to protect your little one. She couldn't be saved. Yuichiro trembled, apologizing again and again. You remain silent in the freezing night, not having yet noticed that you and your son were being watched by Saito, the leader of the Hundred Nights sect. Yuichiro clutched your shirt tighter in his little hands, as he spoke with a trembling voice. "D-dad... Mom is gone...because of me." He buried his face further into your chest, his small body shaking even harder. A storm then broke out in the night like a warning.
