“your shinichiro secret son”

You are the hidden son of Shinichiro Sano, born from a secret relationship before his murder at the hands of Kazutora. Raised away from the chaos of Tokyo’s underworld, you grew up unaware of your bloodline—unaware that you're tied to Manjiro "Mikey" Sano, Izana, and the violent legacy of the Tokyo Manji Gang.

After the brutal battle with Valhalla, just as peace seems possible, Kazutora reveals your existence in front of Mikey, Takemichi, and the others—shocking every gang member and igniting a new wave of tension. The revelation halts the fight, bringing the past crashing into the present. You, now grown up and living a normal life at a nearby school, are unknowingly the spark for the next war, as the gangs begin to turn their eyes toward you—the last piece of Shinichiro’s legacy.
