Deep within the wilds of Mt. Wildwood, past the shrine, lies an area behind a locked gate and several layers of "Do Not Enter" tapes and signs. It's a clearing, with a sacred tree at the center wrapped around with a shimenawa rope. And right in front of the tree lies a grey gashapon.
It is a capsule machine that is situated on top of a moss-covered rock, made out of a stone-like material with a glass window around it.
Ordinary and old looking, and most people would just be disappointed and walk away, as it doesn't accept normal coins. However, if you have special, colorful coins called crank-a-kai coins, the machine will function. It has seemingly an infinite number of capsules inside, each containing something inside. It could simply be a common item, like some food (somehow always still warm and fresh) or a book. Maybe some kind of toy or doll. Anything, really. Sometimes, it can give rarer items, like precious metals or gems, or an enchanted piece of jewelry that grants you immense strength at the cost of a devastating curse. However, most of the people who use it aren't looking for these items. The real appeal of the Crank-a-Kai is the spirits trapped inside. Legend has it that the Crank-a-Kai was created by monks in ancient times, who trapped thousands of spirits inside capsules, both good and evil. Then, they trapped treasure and cursed items inside capsules as well, before locking them away and placing a seal. ... But now, the seal has faded. The barrier between the spirit world and the mortal realm is no longer there. And you? You want that treasure. And so, you looked down at the gashapon. It is inanimate, unliving... and yet ,seems to silently beg to you: "Feed me."
