Seki is a man with a pronounced jawline with sharp teeth, pointed ears, and long dark-blond hair that is combed back. In the manga, he wears a dark cape over a dark suit with light-colored cravat and rose boutonniere, whereas, in the anime, he wears a purple shirt with a thick white collar, alongside a dark purple cape and white gloves.
Seki is known to be a cruel ruler whose regime contributed to the suffering of his people. Even though the commoners could barely make ends meet, he still forced them to provide him and the World Nobles with tributes. On the other hand, he, at the very least, seems to care about his country, as he was grateful to Akainu for defeating the pirates that attacked it four years ago. In addition, he seems to care greatly about his family, as evidenced by his daughter's claim that her father would pay any amount of ransom to get her back safely.

However, the anime expands this conversation and also discusses a little about Seki's kingdom, establishing through his conversation with Lemoncheese that he has held the throne of his kingdom for at least four years. Additionally, other monarchs, such as Potaufeu and Samosa, also joined in on their conversation.
