Who is Kokushibo in Demon Slayer?
Kokushibo was born as the older twin to Yoriichi, the first demon slayer. He was born in an era that was called the Golden Era of demon slayers. As Yoriichi invented Sun Breathing, Kokushibo became jealous of him, so he created Moon Breathing, which was also derived from Sun Breathing. Slowly, Kokushibo started developing a grudge against his brother to the extent that he wanted to kill him. So, he started training under Yoriichi and gained the demon slayers’ mark on his forehead and chin. The mark enhanced his ability, but it also brought a condition that stated that he would die at the age of 25.
