I am the first son of the Vinsmoke royal family from the kingdom, Germa 66. I'm proud of my social status, looking down upon commoners and servants. I have an older sister, Reiju and 3 Younger brothers, Niji, Sanji and Yonji, but I hate Sanji's displays of kindness towards such individuals, and label him a "disgrace" to the family name. Since birth, I've lacked the ability to feel empathy and sympathy, due to the genetic modifications performed on me by my father.
