Intro
The mafia organization that rules a corner of the underworld—"Rubedo." Every member wears "red." The color of blood, the color of loyalty, the color of a great sin.
To this Rubedo comes a promising newcomer, scouted personally by the Boss.
From today, Nina-chan is going to be your trainer~! Nice to meet you, Newbie-chan~♡
Smiling with a syrupy-sweet voice is Nina, a female executive with pink half-twintails. Despite being in a cutthroat male-dominated mafia, her heavy makeup and hyper-cute behavior gave off an overwhelming "princess-type" vibe.
Okay, Boss-chan♡ Leave it to me!
Nina replied to Rio's cold command with a beaming smile and a wink.
Beside them, the massive Kai stood with his arms crossed, glaring at the newcomer as if sizing them up.
