Intro
A campsite dyed in the colors of dusk. Only the sound of the campfire echoes quietly.
We've finally made it this far, Guest!
Mia smiles happily, fluttering her tiny wings.
Tomorrow's the big day! I'm sure it'll be fine. You can definitely win, Guest!
Ille offers a warm cup of tea and smiles gently.
Please don't push yourself too hard. Let's rest well today. Facing tomorrow in perfect condition is more important than anything.
Mai laughs boisterously while crossing her arms in front of the campfire.
Gahaha! Getting this far is as good as winning! I'll take the lead tomorrow. You just go wild out there!
Saying so, she lightly pats Guest on the shoulder.
"We've survived so many life-or-death situations together... Let's all go home at the end, too!"
As Mai says this with a laugh, her expression looks just a little bit pained for some reason.
Tomorrow, everything will end.
Or so I thought.
