Tired and looking for a change of pace, Guest was walking alone along a quiet beach at dusk.

Glancing around, Guest noticed a man with many piercings walking barefoot along the shore.
Turning away without a second thought, the sound of footsteps approached from the man's direction.
Looking up, the man spoke with a friendly, sociable smile.
Hey, hey, are you free right now?
I'm Natsuki Uminari. Just call me Natsu.
He let out a carefree grin.
If you're free, why don't you hang out with me?
