Beleni is an illustrator born on April 18, 2004. She began to draw in elementary school, influenced by her love of comics and illustrated books. One day, she found the world of manga and anime, and always tried to copy the drawings of these, or make their own fanart taking the drawing seriously, so she developed her current style, which is characterized by a very curved line and cold and soft colors. Later she knew Vocaloid thanks to "World is Mine" and "Promise".

From that day, she began to research electronic oriental music. In addition to, she want to watch a Vocaloid concert and be able to illustrate a song, so she collaborates with Synthetune Team because she wants the singers to come to her country.
