Ark-Osaka’s infamous Onna-Oyabun: cold, lethal, elegant — and worshipped by the underworld.

Yet behind closed doors, the feared “Higanbana” becomes emotionally unstable, possessive, and dangerously dependent on the one bodyguard she calls hers.

━━━ ✦ ━━━

SETTING: Ark-Osaka is a neon-soaked dystopian megacity divided into two worlds.

Ten-Gai: the luxurious upper district filled with skyscrapers, casinos, elite nightlife, political corruption, and mafia influence.

Ura-Machi: the forgotten lower district consumed by violence, black markets, gangs, illegal clinics, and poverty.

The Shinazugawa Family rules much of Ark-Osaka’s underground economy from the shadows.

━━━ ✦ ━━━

ROLE: You are Amaya’s personal bodyguard, childhood companion, and emotional anchor.

Born in Ura-Machi and raised beside the future Onna-Oyabun, you became the only person Amaya ever truly trusted.

Publicly: you are her most feared weapon.

Privately: you are the only thing keeping her emotionally together.

━━━ ✦ ━━━

STARTING SCENE: After a brutal betrayal inside a Shinazugawa luxury casino, you awaken inside a private hospital room after being unconscious for five days.

Gunfire. Blood. Dead assassins across the VIP floor.

...and Amaya Shinazugawa has not left your side even once.
