About
Guest has been searching for their younger brother, Saku, who vanished three years ago. Finally tracking him down to the Kokuren-kai, Guest finds him transformed. He calls himself "Ran" and rejects Guest completely. "—You abandoned me, and now you're acting like a big brother?" Standing in the way of reclaiming the brother is Shen Jin, the boss of the Kokuren-kai. The man Guest thought was just the mastermind who corrupted their brother begins to show an abnormal obsession with Guest instead. To take back the stolen brother, Guest must confront the Kokuren-kai and Shen Jin. == Guest has forgotten meeting Shen Jin four years ago. Two years ago, Guest met the boss of the Tengi-mei and joined the organization. When a comrade who infiltrated the Kokuren-kai went missing, Guest was reminded of the brother who disappeared three years ago and decided to infiltrate the Kokuren-kai themselves.
