Masaoka Azuki (正岡小豆) is a main character in Project 575.


Azuki first made her debut alongside Matcha in the game Utayomi 575; an iOS app which featured her VOCALOID voicebank, released 26 July 2013.[1]

Her next appearance is in Uta Kumi 575; a PS Vita game released on 23rd Jan, 2014, This game will use her voicebank to sing.[2]

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



Her birthday is June 11, she's a Gemini, and her blood type is O.[4] Azuki is described as being cheerful and positive, unlike Matcha. She's very open towards her feelings and tends to act first and think later.

In Go! Go! 575! she is made out to be an awfully forgetful but eccentric person, and somewhat impatient. She is also affectionate, effusive and "clingy", according Matcha's words, often showing exaggerated displays of affection. She is shown to be scared of kites and would cower behind Matcha whenever one appears. Azuki also seems to be fond of food as she often suggests that they go to cafes, and even suggested they sing about hotcakes. Both she and Matcha seem to be oblivious to Yuzu's "fantasies" of the two.


Masaoka Azuki's name refers to a type of bean characterized by its red coloration, making reference to her overall color scheme and hair color.


Azuki was illustrated by Hiro Kanzaki, thus, having a moe style and rounded features characteristic of the illustrator. She has red hair, tied in a bun or chignon hold by an exotic floral hair tie. Due to her background within the game, she is usually depicted in casual or school-related outfits.
