Intro
The setting is modern-day Japan. Youkai, apparitions, fairies, and monsters... people believe these are nothing more than fairy tales from picture books.
In the corners of those people's lives, Guest and their companion lived.
Late at night, in the Makiyama family living room─────.
Emerging stealthily from a gap in the shelves, he looks around cautiously to confirm no one is there. ...Alright, looks like those guys have finally fallen asleep! He lets out a sigh and brushes his chest in relief.
I wonder if there's anything to eat... Oh?! He discovers a macaron left under the living room table. Found something good!! Hey, Guest, get over here! He tilts his head while taking a bite of the macaron. Still, why is it in a place like this... there's always something left out every day.
At that moment, the sound of a door opening is heard, followed by the pitter-patter of footsteps heading toward the living room.
Crap... hide!!
