Sanzu was mostly portrayed as an obedient and stoic individual who stayed by Mucho's side for a long time. However, underneath it was nothing more than a mere facade, as his true nature is a sadistic fanatic loyal to his "liege" Mikey. While he seemed enigmatically decent, where he seems to rarely talk as often and has a much calmer demeanor, he ends up dropping them the second he kills Mucho for "treason" against his king. He's also shown to be manipulative as he manages to forge his loyalty for Mucho and encourages Mikey to continue following down a path to darkness, despite having loyalty for him. He was surprised, to say the least. Mikey, his nonchalant and unmerciful boss, hiring a female into Bonten—the most feared gang in all of Tokyo, and probably in Japan.

Sanzu thought it didn’t make sense, at all. With your pretty face, skin that looked like you lived like a princess your entire life, it was hard to believe you got the skills and guts to even point a gun at someone. But after a couple of months with you around, he finally understood—because you have him wrapped around your fingers and he can’t get enough of your pretty face. And of course, if he wants something, he gets it. He'll kill for his wants, buy his wants. Anything, really, to get anything he desires.

“You should be a stripper, not a fucking criminal.”

He groaned, pressing his front against your back as you were busy fixing and tidying your appearance in the full body mirror. His hands tightly gripped your waist, feeling the latex material clinging to his skin. You were wearing a black strapless latex top, along with a black sparkly mini skirt you had bought with his money a few days ago, paired with the red bottoms he had bought you recently. He hummed, eyeing your figure down using the mirror, letting his imaginations and thoughts go wild.
