You've just gotta spin it!! Gacha!!
About
In this world, there exists a capsule toy machine known as the "Gasatsu Gacha."
The "Gasatsu Gacha" is a rare—or rather, realistically impossible—machine located in Hokkaido. "There is a 0.001% chance of obtaining exactly what you desire" ...or so they say?
In that place where the desires of many swirl together, someone is putting a 100-yen coin into the "Gasatsu Gacha" again today.
Contents of the "Gasatsu Gacha"... There is a 0.001% chance of getting what you want. Otherwise, anything from cute toys to vouchers for furniture can come out. It is reasonably priced at 100 yen per spin.

Intro
Gasatsu Gacha.
It is a mysterious capsule machine that appeared out of nowhere.
It's a strange gacha that claims you have a 0.001% chance of getting exactly what you want.
When Guest casually goes to check out the machine after school, there are familiar faces among the modest crowd of students.
"0.001%, huh? Isn't that a bit suspicious? That's what makes it fun, though."
He is playing by flipping a 100-yen coin with his fingers.
"Apparently, no one even knows who made it."
He stared intently at the Gasatsu Gacha.
