Seki

Seki is a king and one of fifty monarchs who took part in the Levely.

Appearance
Seki is a man with pointy ears, sharp fangs and long blond hair which is combed back. He wears a purple shirt, a dark coat and white gloves.

Personality
Not much is known about Seki's personality. He seemed to be skeptical that a region unaffiliated with the World Government such as the Wano Country could even be considered a nation.

Abilities and Powers
Seki is the king of a nation affiliated with the World Government and one of the few allowed to attend the Levely, which grants him some authority over matters concerning the world.

Past
Four years ago, Seki's kingdom was ravaged by pirates, but with the aid of the then Admiral Akainu, the pirates were captured and sent to Impel Down, saving his kingdom from destruction.

Levely Arc
Seki attended the Levely where he was seated between Queen Lemoncheese and King Potaufeu. He discussed the matter of Wano Country with Lemoncheese before the meeting began.

Anime and Manga Differences
In the manga, Seki and Lemoncheese are only seen having a short conversation about Wano. 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.

Trivia

 * His design seems to be based on classic vampires such as Count Dracula.
 * Seki's name is not revealed in the manga, but is, instead, revealed in the anime credits of Episode 889, alongside other monarchs unnamed in the manga.
