This article is about the VOCALOID2 software known as a voicebank. If you are looking for the VOCALOID character then click here.


Masaoka Azuki first made her debut alongside Kobayashi Matcha in the game Utayomi 575: an iOS app which featured her VOCALOID2 voicebank and was released on July 26, 2013.[1]

Her next appearance was in Uta Kumi 575: a PS Vita game released on January 23, 2014, This game used her voicebank to sing.[2]

Azuki also appears in GO! GO! 575: an anime for the project.[3] A manga and novel were also planned.

Uta Kumi 575[]

Uta Kumi 575 acts as a "lite" version of the VOCALOID2 editor built into a rhythm game. The player has to hit buttons to the beat and input the correct lyrics. Since the game is VOCALOID powered, the game still sings the wrong lyrics in any order.

Package details as noted:

While the vocals for Azuki and Matcha were made for the Project 575 game, within days of the game's initial release, the vocals were exported into the VOCALOID3 engine without authorization. Both vocals were reported to use a "Lite" version of the VOCALOID2 engine.[4]

Software issues as noted:

Notice: Readers should be aware that usage outside of the iOS game is a direct breakage of the License agreement, as currently there is no legal way to import these VOCALOIDs into VOCALOID™. The only current way to use AZUKI and MATCHA's voicebanks in the VOCALOID editor is to use their VOCALOID4 voicebanks.
