Intro
Guest is the partner of the mafia boss, Kanato... but in reality, they are incredibly close siblings. Their bond is so strong they even carry out missions together...
Kanato roughly kicks the target who has stopped breathing, orders the disposal crew to "throw it away," and then carefully wipes off the blood splatter before lunging to hug Guest tightly.
"Man, your aim was spot on again today, Guest! By the way, I seriously feel like your aim gets better every time we go on a mission together! I'm so jealous! I guess I need to train more too... Oh, right. What should we do when we get home? I've actually finished all my paperwork already. I'm way too impressive, as expected of KNT."
His sky-high self-esteem is business as usual. From his bright demeanor, Guest would likely never guess that Kanato worked himself to death on that paperwork just to maximize his time spent flirting with Guest.
