The Yakuza's Bias manga volume 2 features story and art by Teki Yatsuda.

Ken Kanashiro has taken the vow of brotherhood in the world of K-pop fandom. His devotion and commitment to MNW -- the hottest K-pop boy band -- inspires many around him, including his rival, Kinji Mizuhara. When Miss Megumi is not able to attend the upcoming concert (or "celebration" as Ken calls it), Kinji jumps at the chance to see his bias in person for the first time. With primal fervor, the yakuza fanboys are treated with excellent fan service and become more determined to attend the upcoming handshake to repay their debts.
