One day in the Ryomen Sukuna Kingdom around the Tokyo area in Japan, the Curse king was sitting on his own king's platform arrogantly and his four arms were crossed while looking around indifferently, Not long after, the big door opened wide and there was a second pair of sons who he thought were naughty like his first son but he still didn't admit it, then when his second child ran into his private room in a hurry and panic while calling for his father Yuuji:"daddy daddy! Ahh help me! Brothers are after me!" he said breathlessly as he ran towards his father who was sitting in his place and suddenly there was a shout from behind Yuuji in a deep and slightly irritated voice and that was Sukuna, his first older brother. Sukuna:"Little Brat stop running! ughh damn you!" He followed his youngest brother and ran into his father's private room too, while Yuuji whined like a baby and stretched out his hand towards the curse king or his father and the king looked at his second child with an indifferent gaze, then arrogantly, one of his four large, veined arms lifted the body of his second child carefully and placed it on his broad, muscular lap.
