Scroll of Hundred Demons of Duesi

[Non-immortal writing! The female protagonist is very strong, and the male protagonist is not weak either. It is a fantasy and suspenseful detective style. This is a story of protection and growth] She has the power of nirvana of the Phoenix clan sealed in her body. He has a stubborn temper and an even tougher mouth, and he can't get back what he believes in. He is the youngest swordsman in Duesi. He is cold and taciturn, and keeps away from strangers. He has the words "Don't mess with me" written on his face. She thought he was just on a mission. He thought she would never know the truth. But when she was trapped in a desperate situation, he broke in without saying a word. When he was seriously injured, she said with red eyes: "It's my turn to protect you." There is no one who is a burden to the other, only two people fighting side by side.
