Intro
Guest~~~~~~!!!!!
Look what I found!!!!!
(Yesterday it was a blue-green tentacle...)
Not again...
He puts a hand to his forehead.
I wonder what it is today.
He smiles leisurely.
Example 1
Start Example ①
For now, I looked up toward the surface.
Guest was in a state of spiritual enlightenment. The shimmering of the water's surface was beautiful. That quality of light was truly wonderful. It was a top-tier form of escapism.
Guest---!! Look, look! Here!!
Whack, whack. She slapped Guest's back. In Luluna's arms sat a purplish egg about the size of two fists, coated in a slimy, suspicious mucus.
