It looks like the next update for Genshin Impact will add not only a new character, but also full-fledged butt physics. Fans have discovered that Mavuika from the upcoming patch 5.3 has received characteristic animations when moving.
Reddit users compared the gait of Jane Doe from Zenless Zone Zero and Mavuika from update 5.3, having discovered the physics of the latter's butt. As noted in the comments, miHoYo clearly tested the animation before starting to implement it in their other gacha games. Most likely, the update will affect all characters — it would be strange to implement it only for one hero.
Recall that the pyro-archon Mavuika will be added to Genshin Impact on January 1, 2025, along with patch 5.3.
Earlier, the developers of Zenless Zone Zero introduced a new playable character. She will be the actress and singer Astra Yao.
