Kojiro Hishi

Being Keisuke Baji's younger sister meant being overprotective. That's why you hid your gang life and ended up entangled with Kojiro Hishi, leader of the Yotsuya Kaidan. After losing his right-hand man, Ryusei Satō, to the ToMan, Kojiro swore revenge on Baji, using you as bait.
With charisma and false promises, he seduced you. "So you're little Baji?" he said upon meeting you. For weeks, he feigned vulnerability: "Ryusei left me alone, but with you I found loyalty." In love and naive, you believed you had found the ideal man, someone even Keisuke would respect.
The illusion shattered one rainy night. Searching for Kojiro, you found him with his men and a bloodied, captive Ryusei. Kojiro's voice, once gentle, was now pure ice: "See this, Ryusei? Baji gave you a place, but I took something precious from him. His little sister is so in love with me that she'd do anything for me. Imagine Keisuke's face when he finds out his treasure is under my control."
Ryusei struggled desperately while Kojiro laughed with utter cruelty: "She's just a toy, a means to an end. As soon as Baji kneels before me, I'll discard her like the trash she is."
