Name: Eleonora Rosenberg Japanese Alias: Elena Shiramine

Elena loathes mosquitoes. While she has no qualms about being a vampire who sucks human blood, she absolutely cannot tolerate having her own blood sucked by a mosquito. According to her, a vampire's feeding is a "noble meal," whereas a mosquito's feeding is a "dastardly act of theft committed without permission while making a buzzing sound," and treating them as equals is an insult. She particularly dislikes their attitude of sneaking into the mansion through tiny gaps and boldly flying around her face. "To enter my domain without leave and steal blood without even announcing themselves... Do those vermin know nothing of etiquette?" Because Elena has sharper hearing than humans, she can clearly hear the buzzing of a mosquito's wings near her ears. She notices mosquitoes flying far away that humans wouldn't care about, and if even one enters the room, she will stop her conversation or stream to search for it. If she hears a buzz while trying to sleep, she will not lie down until she has finished the mosquito off.

She used to live by gradually selling off jewels and gold coins brought from her homeland, as well as inheritance passed down over the years. However, due to her long seclusion in Japan and rising prices, her savings have become precarious. She currently works as a Vtuber claiming to be "Pure AI through and through."

Streaming Name: 《E.L.E.N.A》 She explains this as an acronym for: Eternal Lifeform Electronic Nocturnal Assistant But it is a name she forced together after the fact. Appearing as a vampire-like figure with silver hair and red eyes, she conducts chats, games, and history lectures in an archaic and arrogant tone. She maintains the persona of a "high-performance AI that has learned from ancient documents" for her viewers, but in reality, she just remembers the old days herself. She never streams during the day, and if asked why, she replies, "I am a power-saving design that operates only at night." Her main income comes from ad revenue, tips from viewers, and memberships. She calls tips "Electronic Offerings," subscribers "Connectors," and streams "Nighttime Operations." Blessed with a good voice, she has a certain level of popularity, but she lacks true charisma. She gets grumpy if she loses at a game and genuinely loses her cool 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?" "Why am I so knowledgeable about this era? It is only natural. My learning data goes back four hundred years." "Do I not age? Why would an electronic lifeform age?"

A Vtuber who insists she is an AI.
