Étra

Étra seems to be bossy and self-confident despite her mood swings. She likes to flaunts her chest size and curvaceous figure (to the delight of Eilene and the dismay of Moemi and Yomemi), which is always a gag on her videos.

Despite pretending to be brave, she is a scaredy cat who is afraid of being alone and in the dark. Étra also has a self-destruct button disguised as one of her hairpins.

Étra has long indigo hair, and eyes with yellow-orange irises.

Étra's Twitter account was created in September 2019, while her YouTube channel was created on 10 May 2020. On 18 May 2020, she announced the existence of her new YouTube channel on Twitter. []

* Étra's background has several themes in common with Eilene's previous project for DUO (now Zizai), the well known Mirai Akari. Both are time travelers from the future, both have memory loss due to traveling in time and both are known for their alluring designs.
* At the end of every video featuring her, in a section appropiately called "Declassfied information on Étra (公開可能な情報 koukai kanouna jouhou)" snippets about her personality, interesting facts and mission are shown.
* Étra was a guest on Moemi's first livestream on 11 December 2019.
* Due to the episodic and comedic nature of the videos, many of the information on Étra is inconsequential, it has no sense and it varies from one video to another.
* That's why the real mission of Étra and her memories are different in any single of her appearances.
