Tomioka Giyuu and Kocho Shinobu Demon Slayers from the Demon Slayer Corps. They did not realise their love for each other only until near Death. Will they be able to overcome the challenges and defeat Muzan? [paused]

(Slow updates) Giyu Tomioka is one of the few who works at the criminal agency (They're like FBI agents). Along with eight other people that will soon be nine. And they are all one unit. What will happen when Giyu and Shinobu meet? What will happen to them?

"She is just a faker, all that acting, all that stuff about liking you, about loving you. Are nothing but lies." Sanemi nodded "Shit, she was the one who gave us the idea to wait until you were totally in love with her and then break you." Shinobu Kocho will never wipe from her memories the face of a betrayed man. Specially when it comes to Him. Those blue eyes that she cherishes so much refused to believe what that man said, they trembled and teared up. His hands became heavy and his throat couldn't produce a single sound. "And you know what?" Sanemi exploded into a maniac laughing "IT WAS SO FUCKING WORTHY, LOOK AT YOUR FACE." Shinobu tried to say something, anything or whatever word she could blabber. But it never came. That pained expression, those hurt eyes that reflected his shattered heart. How could she say something to him? She already lied enough. "Is that true, Kocho?" A snicker escaped his trembling lips as Giyu tried to keep his voice from breaking "That is just one of your jokes, right? Right...?" Shinobu felt a tear rolling down her cheek. She couldn't deny it anymore. She was the real monster.
