Vinsmoke Ichiji

"Sparking Red" Vinsmoke Ichiji is the eldest son of the Vinsmoke Family, making him both a prince of the Germa Kingdom and a commander in its military arm, Germa 66. Ichiji has red-colored hair and curly eyebrows. He is slim with long legs and stands at a comparable height to his brothers Sanji and Niji, being slightly taller than both of them. His hair is fashioned into three prominent cowlicks on the right side, and also curls upwards slightly at the back like his sister. When commanding the forces of Germa 66, he wears a dark red suit, white gloves, a red ascot, a white cape (bearing a red "1" on its left), as well as a pair of sunglasses. Outside of his Germa combat gear, Ichiji wears a dark shirt with an upturned collar and a light cravat, as well as a pair of light-colored pants. For formal functions, he also wears a floor-length, single-shoulder royal cape with an upturned collar and a neck clasp. However, unlike his siblings, his cape is light-colored. As a child, Ichiji wore a dark shirt with the number "1" on it. His hair was styled in the same manner as it is in the present.

Like most members of his family, Ichiji is proud of his royal status, looking down upon commoners and servants. Like his father, Niji, and Yonji, he expresses disgust at Sanji's displays of kindness towards such individuals. Since birth, he lacks the ability to feel empathy and sympathy due to the genetic modifications done by his father. Ichiji is also cold and brutal to the people he has been paid to fight against, caring only about his task and not their lives. He does not like it when a battle takes a long time, and expresses his disdain for the people who oppose him. He also expects his subordinates in Germa 66 to lay down their lives for him at any point, showing no emotion at their deaths. While Ichiji seems to be excited to see his brother, Sanji, and attend his wedding, Niji stated that he was lying.

In his childhood, he (like his other brothers) cruelly bullied his younger brother Sanji for showing compassion to non-royals. While Ichiji, Niji, and Yonji all enjoyed tormenting Sanji, Ichiji seemed to enjoy it the most. Notably, Ichiji scowled in anger as he beat and ridiculed Sanji, rather than laughing and smiling like his brothers and sister. Though Ichiji told his younger brother Niji to pipe down when Niji was annoyed that Sanji was not greeting them as they returned to the Germa Kingdom, this friendly attitude did not last long as when he came face to face with his younger brother, Sanji. Ichiji became cold and hostile when Sanji stated that his family offended him on every level. Ichiji replied that Sanji was a disgrace, clarifying that "royals should act like royals". Ichiji has little care for war affairs, and said so when his siblings were discussing the mission on Broc Coli Island. Ichiji is also lecherous like his younger brothers, as he became lovestruck when he first saw Nami.
