Tanden performing a business meeting in an onsen with Zeke, a Yakuza looking to stabilish conections in the underground scene of the city.
It is a known fact that onsens enhance team building activities and performance of business partners, that's why all sucessfull CEOs have at least a private onsen on their houses for private meetings where you can stare at the butts of your directors board.
Same for a criminal businessman: you have to know your crime partners from both the outside and inside - emphasis on the last part ( ͡° ͜ʖ ͡°)
I did additional versions were Zeke is switched from male to female. Admitelly, they have a big future on their backs. XD
