Antilene Heran Fouche appeared in the 2018 TV series called Overlord II. Antilene Heran Fouche (アンティリーネ・ヘラン・フーシェ) is the current holder of the Extra Seat in the Slane Theocracy's Black Scripture. She is the illegitimate daughter of Decem Hougan, the King of the Elf Country and the Scripture's former ace.
Antilene is a woman with heterochromia, for both her eyes and hair. One side of her hair is silver, while the other half is black. Moreover, the skin tone of Antilene's body is apparently pale white. Though she looks fairly young to the point of looking like a teenage girl, her current appearance does not actually match up with her current age. As such her looks have presumably not changed or aged for a long time.
It seems that Antilene is bored with everything, as there is no one who can barely stand a chance against her. In spite of that, she was implied to have been a bit hopeful of facing eventual defeat one day by someone stronger than her through combat. In particular, Antilene wanted it to be that kind of individual who she can potentially mate with if such chances are actually possible regardless of their looks or personality or even Race, expressing genuine giddiness and excitement at the prospect and possibility of how powerful their children could be if she indeed mated with such a man. Crazy and overly excited about that sort of idea, Antilene yearns for a very strong guy who can help the former genetically conceived a powerful child that shared both of their respective bloodlines and genetics combined. However, that thought was a lied, Antilene doesn't want to be defeated, and doesn't necessarily care about having a strong child with a stronger male during her fight against Mare.
At the same time, she hardly ever bears emotion or sadness for the death of someone from the same side. According to the Captain of the Black Scripture, Antilene's attitude was similar to asking about something unrelated to her. For him, this type of attitude fits right in with the style of Antilene. As well as usually ignoring an important announcement from the Cardinal Conference, like the circumstances of her own group.
Due to the circumstances of her birth, she seems to be ashamed of her elven heritage and would constantly hide her ears. Antilene didn't like it when others such as the Captain of the Black Scripture looked at her ears. Nevertheless, she is hardly filled with either curiosity or joy on any specific subject until mentioning a potential candidate for doing battle with. It was the urge to fight that spurred her to have such blood-lust emotions excitingly.
Other than her blood-lust and desire for battle, the only other times the Extra Seat has shown strong emotion is when things regarding her mother arise. As it was implied by the Six Cardinals, Antilene felt genuine love for her mother and cherished her deeply enough to feel immense anger, hatred and contempt for her father the Elf King who violated her. Having already known her mother's fate for a long while, she insisted the higher ups of the Slane Theocracy to start a war of retribution against the Elf Country to avenge her. This goes to show that Antilene is indeed capable of developing genuine feelings of love and attachment to someone despite her generally bloodthirsty and bored disposition.
The Extra Seat was supposedly described to have been born into the New World by a human woman who was once regarded as the Slane Theocracy's previous trump card and strongest God-kin. Prior to the Extra Seat's birth, the Cardinals stated that her mother was kidnapped by the Elf King of the Elf Country, who later then raped her to the point of pregnancy. Eventually, the Extra Seat's mother was then rescued by the Black Scripture, but by that time they came to her aid, she was already pregnant with his child. In a way, she is technically considered to be a bastard child that was brought to life incidentally as a result of an illegitimate relationship between a female human and a male elf.
Antilene’s mother raised her, though provided no warmth or love to her unwanted daughter. Instead Antilene was subjected to unrelenting training that saw her in tears and pain. Her only friend who every showed love to her was a woman named Aunt Nazaire. However Nazaire eventually died and Antilene was left without any support from her abusive mother until the Cardinals decided to separate them.
Ever since Antilene's birth and at her own urging to the Cardinals, a war of retribution has been waged against the elves for what their King did to her mother. As a half-elf, she dislikes the mere thought of people especially her fellow Black Scripture members looking at her ears, but for unknown reasons why. It had been hinted from the Cardinals' discussion that they didn’t think it was a good idea to snatch Antilene away from her mother’s side. Among the Cardinals, one of them thought it was a mistake done on their part at some point in the past to have raised her with that sort of personality.
As the Extra Seat in the Black Scripture, she was given the sole task of guarding the Treasury within the Slane Theocracy as her way of life. It was wherein which the Six Great Gods' sacred items are supposedly preserved in secrecy. In other words, her main job was to focus on safely protecting that sanctuary, a place that even held their five holy equipment.
Additionally in the Black Scripture, which gathered individuals who had reached the Realm of Heroes, Antilene had the duty of breaking in the newcomers and or those that grew arrogant due to their abilities. Said breaking involved demonstrating her superior power over them.
Although Antilene is willing to fulfill her duty at home, she still yearns to go outside and look to challenge potential foes who're likely more powerful than the former, strong enough to outmatch and impregnate her. On that note, Antilene even holds a certain degree of political influence over the minds of several Cardinals to pull them into going to war with the elves. It was believed by the Cardinals that Antilene remain restless and unease of not getting the opportunity to take revenge for what happened to her mother.
