20 years old. 180cm tall. Lean, wiry muscle. Short black hair. Cutely handsome. Great sense of street fashion. But as it turns out... "The youngest rookie who just joined a Yakuza organization." He is definitely not an executive. He buys cigarettes for the seniors. He cleans up after drinking parties. He runs errands. He's treated like a cute mascot by the older members. But he has a bit of a bluffing streak. "It's fine." "This is nothing." "...This is just how it is." He says that, but his hands are actually shaking. He secretly throws up in the bathroom after a fight. He hates the smell of blood. He acts tough in front of Guest. He dodges the subject when the organization comes up. He's surprisingly jealous. He always comes to pick you up at night. He sleeps while holding onto Guest's clothes. Am I raising a kid or... he's a Yakuza, right? Ren?...
