History
Tetogender, along with its alternative names, was first coined on May 2, 2022, by a user who wishes to remain anonymous. It was coined because the user wanted a term and flag to describe their gender in relation to Kasane Teto, alongside labels to describe their gender in relation to Namine Ritsu (Ritsugender) and flower (vflowergender). After this, they coined genders for centered around other Utauloids and Vocaloids as well.

The gender was first publicized on the LGBTA+ Wiki on Miraheze.

The term "tetogender" appears to have been used once prior to this coinage by Twitter user @tetogender as early as the September of 2020, but had no official coinage or flag to be found.

Flag
The Tetogender flag was designed on May 2, 2022 by the same person who coined the term, who wishes to remain anonymous. There is a version of the flag with a music notes symbol, as well as a version without it. The symbol was also created by this anonymous user on May 2, 2022.

The colors of the Tetogender flag were color-picked from an official image of Kasane Teto. The meanings of the colors are left up to interpretation, and do not have a strict meaning behind them.

 * Red: connection to Kasane Teto
 * Pink: gender euphoria
 * Light pink: music
 * Cream: french bread
 * Blue: inclusivity and validation
 * Dark grey: gender envy
