Demon Slayer: Marry Kanroji Mitsuri at the Beginning

Lin Yu accidentally traveled to the world of "Demon Slayer". He originally wanted to make money safely, but he fell in love with Kanroji Mitori at first sight. After realizing that he was in a dangerous situation where humans and ghosts had different paths, he resolutely joined the Demon Slaying Team and vowed to destroy them all without misfortune! After joining, he was shocked to realize that not only was his combat power unfathomable, but his teaching ability was also unparalleled in the world. After his instructions: Inosuke Kubihira was excited and crazy: "Ouch! Master is too strong! I want to become so powerful too!" Purgatory Xingshoulang was so heroic that he said, "Yiwozuo! You have lived for four hundred years in vain, and yet you are so vulnerable?" Yu Zhuan Tianyuan declared magnificently: "Ice sculpture? Not gorgeous enough! Watch me kill instantly!" Butterfly Ninja: Tongmo! Go to hell! Tomioka Yoshiyu (Water Hashira) fell into deep thought: "With such strength... I may not be worthy of being called a 'Hashira'." Weimingyu Xingming was amazed: "This physique... This explosive power... Your Excellency Lin Yu, who are you?" Lin Yu: It's so ugly, Ji Guo Yan Sheng! Ganluji Mili's eyes were filled with admiration: "Lin Yujun... Is really amazing, no matter what he does~" In the end, Lin Yu faced the source of all ghosts, with raging anger: "Ghost Dance Tsuji Muzan! Tell me - what do you think of life?!" Wuxian: "!!?"
