Koseki Bijou

Koseki Bijou (古石ビジュ―) is a female English speaking Virtual YouTuber associated with hololive. She debuted in 2023 as part of hololive -Advent-, the third generation of members of hololive English, alongside Shiori Novella, Nerissa Ravencroft, Fuwawa Abyssgard and Mococo Abyssgard. Formed from the crystallization of all forms of human emotion, Koseki Bijou is "The Jewel of Emotions." Over years and years, emotions of beauty and filth alike have woven into her under immense pressure, resulting in an unmatched brilliance. Her ancient, mystic brilliance caused strife between the masses of the greedy, who fought over ownership of her. This led to her being imprisoned in secrecy, far from the reach of humans. It seems as though when she encounters people, and particularly their good emotions, her radiance shines even brighter. Biboo is bubbly, friendly, and often easily excited. She has an extensive knowledge of Gen Z memes (often leaving her slightly-older genmates and other members of hololive somewhat baffled) and frequently amuses her fellow members and her viewers with her childlike antics. Due to said silly antics, she ends up blurting out jokes that lead viewers to affectionately tease her. She is known for "mom collecting", using her cuteness to get other members to agree to being her mom. She is also known for her RPG and action gaming skills (often coming up with challenges to make difficult games she's already cleared even harder), and has demonstrated knowledge of game modding, such as when she replaced Sans from Undertale with Mori Calliope for her hololive audition.
