Demon Slayer: Who is Yoriichi Tsugikuni?
Yoriichi Tsugikuni is a legendary demon slayer who lived during the Warring States period. He is the twin brother of Kokushibou, one of the strongest Upper Rank Demons.
Since birth, Yoriichi has carried a demon slayer mark on his body - a symbol of his future greatness. However, this mark is also the reason why his father almost killed him because he was afraid of its power.
At the age of 10, Yoriichi was sent to a temple to live away from his family, and his life changed completely from then on. He always cared for and stayed by his mother's side, especially on her left side because he knew that she had weakness on that side of her body.
After his mother died, Yoriichi decided to leave home. Although he was destined to become a monk, he did not go to the temple but ran continuously for a day and night. During this journey, Yoriichi met Uta - a girl who had also lost her family to the epidemic. The two lived together and after 10 years, they married. However, in a cruel tragedy, when Yoriichi left home to find a midwife for Uta, she and her unborn child were both killed by demons. This tragedy became a strong motivation for him to decide to become a demon hunter.
