For full context, Okayu stole Lui's elytra earlier and ran away. After some time passed, Okayu and Gura were making out Minecraft-style until Lui came to confront her about the elytra. The bird hag then threatened to snitch to Korone, to which Gura and Okayu responded by beating her to death. After which, Okayu killed Lui a few more times until Lui got some diamond armor and got revenge. Gura got forgiven because she's cute and it works literally every time. They then agreed to make peace and I'm assuming Okayu returned the elytra. What you see is Gura trying to preemptively defend herself before Korone sees the evidence and decimates her.
Korone actually streamed Minecraft earlier today so I think she'll hop back on soon enough. I'm expecting a 20min+ clip of the whole thing once the doggo sees what happened. This entire fiasco was hilarious and honestly block game is good because random ass interactions like this can happen outta nowhere.
