Sleep Emote

[KizuyaKatogami]

I can't remember the specific scene you're referencing, but Valens uses an Elezen model and they do a slow clap just as their regular /clap emote. So it may not be a new emote for them to implement.

Believe it’s the slow clap he does when saying “burn out the bad” it’s the one that’s typically translates irl to like… “Get.It.Together.”
