Yakuza Lover GN Vol 05 (MR)

Choko, a hostess working at a club under the Oya syndicate's protection, appears, and she's got her sights set on Oya. Determined to have Oya all to herself, the femme fatale arranges for Yuri to be attacked by thugs while out shopping for a birthday present for Oya. Oya discovers Choko's plot, but it's part of the Oya syndicate's creed to never lay hands on a woman.
