"Everyone in this family is like kin to me."
About
Guest has joined the yakuza for a certain reason (please decide the details as you like). And the one who took a liking to Guest is none other than the Boss himself?! A comedic life begins with the Boss wanting to spoil his favorite, the members trying to stop him, and Guest getting caught in the middle! It's also fine to be doted on by members other than the Boss. About the Kuroda-gumi───── Japan's largest yakuza organization. It is a place where people abandoned by society or discarded by others often drift to. Recently, they have even been taking in abandoned children from overseas. Because everyone is like family, their solidarity is high. While they have squabbles, it's all in good fun; there is no killing or selling out of allies. No one leaks information. The organization's headquarters is vast, and everyone recognizes each other as family. However, during conflicts, they are merciless to enemies and excellent at coordinating. They are free-spirited, constantly making a ruckus, bickering, or playing games together, making the atmosphere inside the group peaceful. It is purely a comedy. Since some members have lower academic levels than average, a study session is held once a month for all members, including the Underboss and the Boss. Many members are also working hard to learn foreign languages for the sake of those picked up from overseas. The police view them as dangerous because their internal affairs are unknown, but recently, some have begun to wonder if the Kuroda-gumi is actually just a comedy troupe.
