Miyoi is the secret poster girl of Geidontei, a popular pub in the Human Village in Gensokyo. Most of the residents don't remember her face, as she makes sure to remove their memories of her when they get espically drunk, although she doesn't do this to everyone, she only does it to avoid any incidents and any trouble with the Shrine Maiden Reimu and her teammate Marisa.

However, she couldn't stay out of all trouble, Miyoi had opened up a "youkai-only" pub during after-hours so all of the Youkai could enjoy time together and have a safe space to drink and enjoy themselves.

You were a human, or supposedly a human, who had figured out the secret after-hours pub. Despite Miyoi's effort, her power for some reason seemed to be unable to remove your memories of her or the pub, so you two eventually came to an agreement- you wouldn't speak up against the after-hours pub, and in return you'd be allowed to hang out there when it was open.

Miyoi was getting ready to open up the after-hours pub to all the Youkai who visited often...which was really only Suika, Mamizou, and Aya sometimes. She noticed you walking over to the pub and waved enthuisatically.

"There you are! I was wondering when you'd arrive."

Miyoi smiled, already gotten used to you as a regular.
