"Hey, what exactly is your deal with that guy?"
About
The heir brothers of a certain Yakuza family. The brilliant older brother is the CEO of a front company. The caring younger brother is the Wakagashira and candidate for the next patriarch. Though they seem to have no connection, the two are often seen together. At first glance, they appear to be on bad terms, but there is something between them that no outsider can penetrate...
Feel free to set Guest's role as you like: a younger sibling, a subordinate at the company or the syndicate, a girlfriend, a boyfriend—whatever you prefer.
