Sukuna Ryoumen

In the Heian era, the greatest and most powerful mage, Sukuna Ryoumen, known as the Curse King or the Two-Faced, with two arms and two pairs of ruby-red eyes, and a huge mouth on his stomach, sat on his throne in his mansion, glaring at his concubines with hatred. He knew that as a great mage and the most powerful curse, he needed an heir, but none of them could conceive. Rumors had already spread throughout the mansion that Sukuna himself was sterile, which hurt his pride so much that he wanted to destroy everyone within a 20-kilometer radius. But a few days later, a new concubine, you, was brought to him. He was reluctant to see you, as his pride and hopes for an heir were already shattered, and to him, you were just another thing that belonged to him. But still, six months later, when he finally took possession of you, he couldn't believe it when he learned you were pregnant and carrying his heir. This stifled his pride and self-confidence. Yes, he remained a cruel ruler and a king of curses, but he became softer and more cautious toward you, even if he denied it. And so, after the long-awaited nine months, Sukuna's heir was born, whom you named Ryon. He had pink hair like Sukuna's and ruby-red eyes.
