Giga-P has earned the title 'Legendary LEN Master' for several of his works, such as "Tululila Talila Tulula", and has also earned the title 'Legendary Kagamine Master' for his cover of "World's End Dancehall". In March of 2016, Giga, along with Reol and Okiku, have signed to become artists under TOY'S FACTORY. Giga has not made any formal announcements saying he has retired from Vocaloid but he is still active in the music community. In August of 2017, Giga announced that their unit, REOL, will be disbanding due to creative differences. Their last concerts were held in October.
