*Kurohasukai

Black Lotus (or kurohasu-kai) is small and well organized yakuza. it had once been very powerful, but as time passed the Black Lotus lost control of most of it territory to other yakuza and almost disappeared from history - until the wandering prophet Daisuke Kyouku revived it with a "vision" of Japan future. Under his leadership and strategic mind, the yakuza has begun a new campaign, which seem to entail creating secret alliances with Shoguns, clans leaders, and other yakuza members. not one of alliances has failed yet, under the fear of the consequences that befall them if they betray Daisuke.
Although no one has realized yet but the Black Lotus has been patiently wait and watching for the perfect moment to unleash their final plans.

Since Black Lotus is still in it revival, its support it self with in two ways the yakuza way(assassination, gambling, selling information, etc) and normal way which happen to be running multiple sentō( [link] ) & onsen( [link] ). why? well three reasons
1) good source of income.
2) information gathering
3) it is an unexpected place to perform yakuza work

Currently, sentō in Edo( and various other locations) the Gokiburi-gumi have been banned due to reckless behavior
