| DECO*27 (デコ・ニーナ Deko Niina, born December 16, 1986) is a Fukuoka-born VOCALOID original song producer and utaite. His first work got over 100,000 view counts quite suddenly, and his current popularity is stable. His style has been described as a fusion of rock and pop.
On November 11, 2009, it was revealed that DECO*27 was male by a video uploaded on Nico Nico, featuring him singing a different key of "Kimi Ijou, Boku Miman". In an interview with MIKUBOOK, he revealed the origins of his producer name. He picked "DECO" (which means "forehead" in Japanese) because he has a large one, and "2" and "7" because they are his favorite numbers. A glance at his keyboard inspired the asterisk. The numbers "27" are read "nii-na", as per the Japanese pronunciation.
As of recently, DECO*27 has been stretching his limits outside of Vocaloid. He composed and arranged a song called "FEVER" for the Hello! Project group Buono!, which was the first track in their mini-album SHERBET.
