Context: When Gura and Amelia were visiting the Hololive JP server they met Aqua outside her home, which has a lot of berry bushes out in front of it (which have thorns that do damage in Minecraft). Gura jumped into Aqua like a puppy and pushed her into the bushes, and she died after a few seconds. Gura was mortified. Aqua laughed about it later.
While her death was pretty funny, but before Gura's push Aqua did move through those sweet berry bushes for a long time so she has almost no hp left when she got push.
