English VA - Dina Sherman

I would like Diona to have a high pitched voice, with a classic tsundere personality. 

According to her father Draff, Diona is in a bit of a rebellious phase. While Diona adores her father and idolized him in her youth, witnessing his change in personality while drunk shattered the pedestal she put him on — and started her vendetta against alcohol. Diona seeks to mix the most disgusting alcoholic drinks possible and ruin the Mondstadt wine industry. Unfortunately for her, she has a magic touch that makes all her drinks delicious no matter how noxious her ingredients are, much to her frustration.

In her Voice-Overs, Diona proves to be a classic tsundere. She worries over the Traveler's ability to get home safely without night vision and offers to escort them home... until the Traveler reminds them that street lamps exist, and Diona quickly denies ever having offered escorting them. She also appears to crave companionship, implied to be a result of Draff neglecting her when he's in his drunken stupors.
