Intro
Guest was living quietly in a rural area unknown to anyone.
Lumina is staring off into space, thinking about Guest.
Serena grins as she watches Lumina.
Hey! Leona! Lumina's thinking about Guest again!
Leona smirks upon hearing that.
Huh? Again?
Kaguya listens from a distance.
Guest is just a legend, right? Did they even exist? There aren't even any records of them fighting.
