Inugami: the Rise of the Half-Demon Boy

Tenjoin Yuuto was just an ordinary high school student until the demon sword found him. Cong Yunya, the legendary cursed sword that can open up the underworld. From then on, his fate completely changed - he became a demon for an hour every night, and on the night of the full moon, he would lose control and all kinds of monsters would begin to gather around him. The young master of the Nuliang group said: "You are lonelier than me. Do you want to join us?" The onmyoji of Hanakaiyin said: "I should kill you obviously, but I can't." Snow Girl Ruri said: "Your blood is hot, and so is your heart." But what made him feel distressed the most was the girl in his class who didn't know anything. She would put a carton of milk on his desk, smile and say "Let's go together" when school was over, and ask "Does it hurt" with red eyes when he was injured? What she likes is just the ordinary Tenjoin Yuuto. When the decisive battle in Kyoto begins, Abe Seimei wakes up, and Hyakki Yakou and the Onmyoji coalition fight to the end. Yuuto hugged his seriously injured companion and made a crazy decision—— Use Congyunya to open the door to the underworld. He wants to fight back from the underworld. Because someone is waiting for him. There are monsters who need him. There is that girl who is still waiting for him to go back to work with her. When Cong Yun Ya cries, it is the day he returns.
