Masaya Oya (大箭将也), also known as Camellia (かめりあ) or Cametek, is a Japanese producer of eclectic electronic music, who began his career largely with Vocaloid songs. He was born in 1992 and started making music when he was around 10 or 11 years old. His music back then was inspired by a variety of different genres and styles but with his interest for technology, which would grow over the years, he took a lot of inspiration from bands like Kraftwerk and Yellow Magic Orchestra

In his works, he has most often used the Vocaloid 初音ミク Hatsune Miku for vocals, most notably in “Systematic Love.” One of his best-known songs is his collaboration with Nanahira (ななひら), “Can I Friend You On Bassbook? Lol.”

Additionally, a number of his non-Vocaloid works have appeared in Konami’s series of rhythm games Bemani, and other rhythm games like osu!, Dance Dance Revolution and such. He created an official demo for VY2v3.
