[Yamada Hideki] Manyuu Hikenchou Vol.2 [biribiri]

In an Edo-era Japan where the shadowy Manyuu clan can freely control and enlarge breasts, wielding assassins and secret government influence, bust size means everything. A struggling painter who dares to draw flat chests finds his life on the line when a voluptuous swordswoman corners him on a bridge, taunting him to sketch her bountiful curves before his time runs out. Between midnight recruitment offers, family greed, and razor-sharp blade work, survival hinges on learning just how far the Manyuu will go to keep their grip on power.
