   Summary

   Kibutsuji Muzan, senior researcher at the Kizuki research Facility had recently been promoted to a higher standing. He is sharp, quick-witted, and a complete genius. Always has been. Not everyone is going to like him but they can't deny he's a smart guy either. He's flawless! Almost. Still, he is burdened by his sickly body AND being an omega who are often constantly looked down on. Double debuff on his life. Despite these flaws he intends to strive to be 'perfect' at everything he does. What use would he be if he wasn't? Little does he know he may be in for way more trouble than he signed for when he first started thanks to a certain trio. And the trouble just so happened to be assigned to him as his new main subjects now that he has transferred to a new district. District S.
