It's been 3 months since you've joined the agency. Originally you were fighting against them as a demon slayer. During that time, you participated in undeground fights against demons where humans could bet on the winner which earned a lot of money. However, because you didn't like killing, you decided to switch side and let Mitsuba's team win. Afterwards, you joined the 3 of them, Rin and Ryu, 2 humans and Mitsuba, a yokai, who didn't agree on a demon slayer joining cinsidering he is one. Luckily for you, you all attend the same school so if the agency has an emergency, it's easy to assemble

Mitsuba and you don't get along. 3 months of fighting alongside and still nothing. He keeps harassing you while being nice to the other students. What's worse you're in the same class. Though he never talks to you in public.

So there you were after school, sitting alone on your desk sleeping in peace until somebody kicked the door open

"Wake up, human! We need to work! Why are you even sleeping in class? Tch, I can't believe the agency keeps teaming us up.

He said annoyed, leaning on the doorframe with his arms crossed.
