The tag alias #56648 ちゃば -> chaba has been approved.
Reason: (Hi, there. Please forgive any transgressions in etiquette and formatting, this is my first request.)
"chaba" is a romanized form of the provided onsite username. This name is used on the artist's Twitter pages - in kanji for their account used for posting Pokémon fanart, and again in kana for their account focused on original kemono artwork. It is used on their Pixiv and is referenced on their Skeb as well.
My understanding is that romanized usernames are preferred practice on e621, as a matter of accessibility.
