Earth Clouds splitting... common sense
Daft Punk Song: Two ways to go either "the legend of the phoenix" or "what keeps the planet spinning" based off lyrics
Biting: a lot of different interpretations, if it's like the last couple chapters where they change scene, it might be another fight where someone bites, maybe Neko or someone.... just spitballin
Level Up: Common sense: Someone transforming, probably something we have not seen from said character so
Again just me totally guessing and spitballin
