DECO*27 (Deko Niina) broke onto the VOCALOID scene in October 2008 and immediately caught people's attention—his debut track racked up over 100,000 views surprisingly fast. He's been one of the prolific producers to emerge in that wave of late-2000s VOCALOID creators, and his fanbase has remained solid over the years. He's best known for blending catchy melodies with clever production, and fans tend to gravitate toward his darker or more experimental tracks alongside his more accessible pop-influenced work.
