Ryuto

Ryūto (リュウト) is a Japanese VOCALOID developed and distributed by Internet Co., Ltd. as Gachapoid (ガチャッポイド), and was released in October 2010 for the VOCALOID2 engine. Later, he was given an update and was released in September 2014 for the VOCALOID3 engine. His voice is provided by Japanese voice actress, Kuniko Amemiya (雨宮邦子; Amemiya Kuniko).

Etymology
His software name, "Gachapoid", is based on the name "Gachapin", the character he is modeled after. The suffix "poid" on the end of the name is short for "like Vocaloid". Thus, the full implied name of this product is "Gachapin-like Vocaloid".

A notable mistake within the western fandom is labeling Ryuto as "Gachapoid" or "Ryuto Gachapoid". The explanation for both these mistakes is the confusion over the naming of both software package and VOCALOID. The same issue occurs with Camui Gackpo and his software Gackpoid along with GUMI and her software Megpoid.

Appearance
His appearance is based loosely on Gachapin's own appearance. It also takes aspects of YAMAHA's "Yamaha XG" midi sound card.

Marketing
Gachapoid was marketed as a children's VOCALOID designed for singing childrens' songs. He was aimed at young producers. His human form was released late after the announcement, along with his human avatar's name of "Ryuto". He was a departure from the more standard box packages that VOCALOID™ had offered previously. He was also released as a promotional tie-in with a Gachapin promotion.

A special promotional CD case was offered at his time of release.

Trivia

 * His human form wasn't added until right before his release and is not on his box, unlike many other VOCALOIDs. Therefore, early works by fans featured a very different character than the one ultimately introduced, or Gachapin himself takes Gachapoid's place as the song mascot. More art was later added of his humanoid character.
 * His mascot's name "Ryuto" wasn't revealed until the illustrations of his humanoid form were released.
 * He was the first VOCALOID by Internet co., Ltd not to be a "VOCALOID artist" voicebank.
 * Ryuto is based on Gachapin, but he isn't Gachapin himself.
