The sound a japanese cat makes. Much like the American 'meow'.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

It's the sound of boredom. It plays when boredom is lurking.
