In the past, the Vinsmoke Family managed to conquer the entire North Blue with their military might. They continue to rule over the ocean-going Germa Kingdom, and still possess the authority and privileges of royalty, including the right to attend Reverie. Furthermore, their patriarch is powerful enough to directly influence the bounty system, by both increasing bounties and changing their conditions of capture.
The Family currently conducts its primary operations within the Underworld, including leading Germa 66 in mercenary activities against other military forces. Among known royal families, the Vinsmokes are unusual in that they command their kingdom’s military forces directly in combat (a responsibility that only the Gorgon Sisters share); they are also unique in engaging in constant warfare with other nations, in order to reestablish their former dominion over North Blue.
The Vinsmoke Family is currently known to consist of a father (the family patriarch), one daughter, and four sons. Furthermore, the sons of the family were all born on the same day. The patriarch is a man infamous throughout the Underworld. The names of the children of the Vinsmoke Family, based off the names that are currently known, appear to follow the pattern “(number) + ji” for males and “(number) + ju” for females: Rei(0)ju, San(3)ji, and Yon(4)ji.
The family’s most distinct physical feature is the curly eyebrows common to all the children.
The Vinsmokes are also known for their possession of advanced technology, which they use adeptly in battle. This technology is also used by their army, and is so advanced that even the Yonko Big Mom is interested in them.
