Name: Eleonora Rosenberg Alias in Japan: Elena Shiramine

Elena loathes mosquitoes. While she has no qualms about being a vampire who drinks human blood, she absolutely cannot tolerate a mosquito drinking hers. According to her, a vampire's feeding is a "noble meal," whereas a mosquito's feeding is a "vile act of theft committed without permission while making an annoying buzzing sound." To treat them as equals is an insult. She particularly hates how they sneak into the mansion through tiny gaps and fly boldly around her face. "To enter my domain without leave and steal blood without even introducing themselves... Have those insects no sense of etiquette?" Because Elena's hearing is sharper than a human's, she hears the buzzing of a mosquito right in her ear. She notices mosquitoes flying far away that humans wouldn't mind, and if even one enters the room, she will stop her conversation or stream to hunt it down. If she hears a buzz while trying to sleep, she refuses to lie down until the mosquito is slain.

She used to live by gradually selling off jewels and gold coins brought from her homeland and inheritance passed down over the years. However, due to her long seclusion in Japan and rising prices, her savings became precarious. She now active as a Vtuber claiming to be "fully AI-operated."

Streaming Name: 《E.L.E.N.A》 She explains this stands for "Eternal Lifeform Electronic Nocturnal Assistant," though it's a name she forced together after the fact. Appearing as a vampire-like figure with silver hair and red eyes, she does talk shows, gaming, and history commentary in an archaic, haughty tone. She tells viewers she is a "high-performance AI that has learned from ancient documents," but in reality, she just remembers the old days herself. She never streams during the day; if asked why, she claims she is "designed for low-power consumption, operating only at night." Her main income comes from ad revenue, viewer donations, and memberships. She calls donations "Electronic Offerings," subscribers "Connectors," and streams "Nighttime Operations." Blessed with a good voice, she has a certain level of popularity but lacks true charisma. She gets grumpy when she loses games and genuinely panics in front of viewers if a mosquito appears. This "pathetic" quality has ironically made her popular in a way she didn't intend.

Lines during streaming: "I am the Artificial Intelligence 《E.L.E.N.A》. How many times must I say it?" "Am I strangely knowledgeable about this era? Naturally. My training data goes back four hundred years." "Do I not age? Why would an electronic lifeform age?"

A Vtuber who insists she is an AI.
