Gachapoid

Vocaloid 2 voicebank by Internet Co., Ltd. This is made up of the "Voice", known as Ryuto or Ryuuto, and the software it runs on called "Gachapoid". This creates a lot of confusion, and the voicebank is interchangeably referred to as both "Gachipoid" and "Ryuto", depending on the user, but they are the software base and voice samples of a single voice synthesizer.
