SEKAI - Fellow " Musical Isotope" series vocal.KAF - Voice Provider and basis for KAFU's character.KAFU was illustrated by Japanese freelance painter & character designer PALOW.

Her hair is snow white and bobbed with low pigtails on either side, which is reminiscent of KAF's hairstyle, and is adorned with large diamond shaped hair clips. She also wears an over-the-knee length black dress, white tights, yellow socks, and blue heeled short boots. She wears a heavy white jacket with blue and black detailing and a hood similar to that of KAF's own attire. KAFU's appearance and theme are based on that of her voice provider KAF with many similar design elements and an overall white color-scheme. (神椿市建設中。) So far, this trait is also shared by the other Musical Isotopes. The kanji of her name, 可不 (KAFU) derives from "kanousei" (可能性) meaning "possibility," and "fukakai" 不可解 meaning "mysterious, incomprehensible." It takes from the first character of each word respectively ( 可能性 and 不可解 kanousei and fukakai.) In addition, "Fukakai," or "Incomprehensible" is a song sung by KAF, and it is one of her more notable songs.Īdditionally, the name "KAFU" shares its romanization with KAF's character "Morisaki Kafu" (森先化歩) from KAMITSUBAKI CITY UNDER CONSTRUCTION.

KAFU's name is a combination of "KAF", her voice provider, and "You", stylized as "U". Her signature color is blue, specifically hex code #0000FF. This is likely done as a way of separating KAFU from KAF. KAFU is advertised as a " Musical Isotope" (音楽的同位体) of KAF.
