Career

Sophia Valentine's YouTube channel was created on 24 October 2022. Her X (formerly Twitter) account was set up in January 2023, and she posted for the first time on 16 January 2023. On that day ANYCOLOR announced seven new female NIJISANJI livers, Sophia among them. Their debut streams ran as a relay on 19 and 20 January 2023.

Sophia was the fourth member of the group to stream, on 19 January 2023. During her debut she played guitar and sang a short version of a song by Yorushika. Her group was later named Idios. It also includes Igarashi Rika, Koshimizu Toru, Ishigami Nozomi, Kuramochi Meruto, Kaburaki Roco and Shishido Akari. Her YouTube channel was opened to monetization and channel memberships on 2 February 2023.

Since her debut she has appeared in group projects with her Idios unit-mates and in collaborative events. For example, she entered the "KZHCUP in STREET FIGHTER 6" tournament and took up the character Blanca with the Modern control type for it. Idios began music activities as a unit in 2025. Sophia has also had NIJISANJI merchandise, including birthday goods and voice packs, such as the 2026 set sold from 14 to 20 February 2026. She was also part of the "Tipsy Voice Vol.2" voice product line.

Activities

Streaming style

Most of Sophia's content is free talk and gaming. She has run first-time playthrough series such as Stray and Monster Hunter: World, in which she plays as a newcomer to the game. Fan sources describe her voice as soft and her streaming manner as calm compared with many of her Idios unit-mates. Shortly after her debut she began showing creative skills on stream and in videos, including songwriting, composing, 3D modelling and animation in Blender, and video editing. One of her projects was a self-made 3D animation of Colobbit, for which she also composed the background music.

Characteristics

NIJISANJI's official profile calls Sophia an otaku who loves the mascot character Colobbit and always carries Colobbit items with many different expressions. The profile also says she is bold online and talkative in text, but becomes nervous when she speaks. In her backstory she is a spy and information broker with the code name "Rabbit". She is training to become a first-class, multi-talented spy, and she was sent into this world from another one after accidentally using a special weapon during a mission. On stream she has jokingly said she is "99.99999% human."

Fan wikis note that, apart from a few exceptions, her name is the longest among NIJISANJI JP livers. Her blood type is O, and her February 14 birthday matches the "Valentine" in her name. Her stated interests include Colobbit, horror films and the series Detective Conan. Fan sources often compare her personality to that of Amamiya Kokoro, describing her as soft-spoken, kind and hardworking but shy and sometimes clumsy. Early on she was seen as the most "seiso" (proper) member of her debut group, but fans and unit-mates have questioned that label because of her offbeat stories.
