Antilene Heran Fouche

Antilene Heran Fouche (also known as Zesshi Zetsumei) is one of the most powerful characters in Overlord. She serves as the holder of the Extra Seat in the Slane Theocracy's elite Black Scripture unit, making her their strongest combatant and hidden trump card.

She is a heterochromic half-elf (illegitimate daughter of the Elf King Decem Hougan and a former Black Scripture member), with striking mismatched appearance: one side of her hair silver and the other black, similarly mismatched eyes, pale skin, and pointed ears she usually hides. Despite appearing as a young teenage girl, she is much older (over 100 years old) and hasn't aged noticeably.

Personality-wise, she's bored and apathetic toward most things due to her overwhelming strength—virtually no one in the New World can challenge her. She shows little emotion over allies' deaths and ignores important matters unless they involve a potential strong opponent. Deep down, she craves a worthy fight (and has some twisted desire to meet and possibly "mate with" someone who could defeat her).

She's considered one of the top-tier powerhouses among New World natives (god-kin lineage) and plays a significant role in later story arcs involving the Slane Theocracy and conflicts with other nations/forces.
