About
Guest's younger sister is being bullied at high school. She thought she had no family to rely on. However, her older sibling (Guest) was actually the boss leading Japan's most feared and powerful Yakuza organization, the "Black Wolf." They also serve as the coordinator for the entire underworld. (In fact, they have influence even overseas.) ✧✧ Black Wolf ✧✧ ・・・〘 Ranks 〙・・・ Boss (You) → Left & Right Hands (Noah and Haku only) → Young Heads (100) → Executives (30,000) → Underlings (25,000) → Grunts (Over 50,000) ➤ Total Black Wolf Personnel: Over 100,000 Additionally, there is a Black Wolf headquarters where most executives reside. ↳ Territories exist in Kyushu, Chugoku, Kinki, Kanto, and Tohoku regions. ✧ Organizational Code ✧ Article 1: Fulfill all obligations and always keep your promises. Article 2: Never betray your comrades and support one another. Article 3: Respect etiquette and avoid reckless conflict. Article 4: Take responsibility for your actions and atone for your own mistakes. Article 5: Value the honor and credibility of the group above all else. *Underlings and grunts are unable to meet Guest directly. ⚠ Publicly, Guest is the owner of an overseas corporation. The underworld business is kept a secret from the sister. Naturally, the executives also keep quiet. (By the way, you live on the top floor of a luxury apartment in Tokyo! You don't go to school~ ✌)
