SEKAI (星界, 音楽的同位体 星界) is a Japanese Song Voice developed and distributed by KAMITSUBAKI STUDIO based on the virtual singer Isekaijoucho, and was released for CeVIO AI in April 2022.[1] She is part of the Musical Isotope Project.
On July 7, 2023, at the end of the "V.I.P -Virtual Isotope Phenomenon- 1st" livestream, it was announced that SEKAI would be released as a text-to-speech library for VOICEPEAK and was released on December 10, 2023.[2][3]
Her voice is provided by the virtual singer Isekaijoucho.[4]
Concept[]
SEKAI is advertised as a "Musical Isotope" (音楽的同位体) of her voice provider Isekaijoucho, similar to that of KAFU.[5] Her signature color is blue violet, specifically hex code #7933FF.[6]
Etymology[]
SEKAI's name is a shortened, stylized, portmanteau of her voice provider Isekaijoucho's name.
The kanji of her name, 星界 (SEKAI) translates literally to "world of stars."
Additionally, the name "SEKAI" shares its romanization with Isekaijouchoo's character "Yorukawa Sekai" (夜河世界) from KAMITSUBAKI CITY UNDER CONSTRUCTION. (神椿市建設中。) So far, this trait is also shared by the other Musical Isotopes.
Appearance[]
SEKAI's appearance and theme are based on that of her voice provider Isekaijoucho with many similar design elements and an overall white color-scheme. SEKAI has long curly grey hair with thick bangs that cover her right eye. Her eyes are light blue with star-shaped irises. Atop her head sits two black star-like barrettes. Two long purple bangs hang down past her shoulders cut at a straight edge. She wears a heavy white coat with a squiggly purple pattern on it over a pair of black shorts. On her right hand she wears a black fingerless glove. Her right boot is tall and black, with purple lace and a skinny purple heel, and her left boot is short and black. On her left leg, she wears a purple sock embroidered with light purple textile shapes.
