Personality
Niji is businesslike, making sure to collect payment for Germa 66's commissions. He appears to be astute, as he claimed that his brother Ichiji's excitement to see Sanji was a lie.

Vinsmoke Judge
Niji's father highly values his "beloved" second son. He approved of Niji bullying Sanji as a child, and refused to consider marrying him off to one of Big Mom's daughters even to seal a powerful political alliance.

Vinsmoke Reiju
As of yet, not much is known about Niji's relationship with his elder sister. However, Reiju was seen smiling at his return to the Germa Kingdom, implying that, at the very least, their relationship is friendly.

Vinsmoke Ichiji
Niji appears to get along well with his older brother, alongside whom he has co-commanded Germa 66 forces in combat situations.

Sanji
As a child, Niji, alongside Ichiji and Yonji, used to bully Sanji for his "un-royal" habit of cooking. Niji also expressed annoyance at the fact that Sanji did not greet himself and Ichiji upon their return to the Germa Kingdom; Sanji, for his part, trembled slightly at their return, implying that he may retain traumatic memories from their abuse.

Vinsmoke Yonji
Yonji used to accompany his two oldest brothers as they bullied Sanji, showing that they, at least, got along. He was also excited at the prospect of a reunion between Niji, Ichiji and Sanji.

Subordinates
Niji's subordinates in Germa 66 revere him as one of their commanders, cheering him and Ichiji as they returned from their brief campaign in Broc Coli Island. As a member of their royal family, each soldier is also willing to lay down their life for Niji if commanded to do so.

Abilities and Powers
As a prince of the Germa Kingdom, Niji has political authority over its subjects. He also holds a high ranking in Germa 66, possessing authority over common soldiers who will die for him on command. A portion of Germa 66, under Niji and Ichiji's command, was able to end a two-year war in four hours, thoroughly annihilating the side they were hired to fight.

As a member of the Vinsmoke Family, Niji also has access to the advanced technology developed by his family as well as their extravagant wealth.

Past
Niji was born on the same day as his three brothers being the second son and the third child of the Vinsmoke Family.When they were children, Niji, Ichiji, and Yonji bullied Sanji for feeding those they considered rats.

Totto Land Arc
Niji and Ichiji led a platoon of Germa 66 soldiers to end a two-year war on Broc Coli Island. They did so in four hours, and Niji collected the payment for their services from the winning side. Niji and Ichiji then stood on a rooftop to observe the burning country, as they arranged to make the two day journey to Whole Cake Island. While Ichiji expressed excitement at seeing Sanji again, Niji called him a liar.

Two days later, Niji and Ichiji arrived at the Germa Kingdom. Niji was annoyed that Sanji was not there to greet them, but was told by Ichiji to quieten down as they received a hero's welcome from the Germa 66 soldiers. Observing from a castle balcony, Sanji trembled at his older brothers' return.
