After Xing Jian Yue was created by the Dimension Witch, he was accidentally awakened and inherited her wish shop.
Here, anyone with a connection to the shop can have any wish granted, as long as they pay a sufficient price.
And so...
In the Taisho era, solar-powered flashlights appeared, along with Hiyobo, who loved turning into a doll and adventuring everywhere.
A certain scumbag boss let out a terrified scream: “Don’t come any closer!!!!”
In the Warring States era, wholesale versions of the Shikon Jewel appeared, along with Kagami Hime, who was obsessed with using mirrors to reveal the true forms of demons.
The dog-demon brothers and a certain lord protested.
In the Heisei era, anywhere doors appeared, along with a Zashiki Warashi who kept suddenly showing up in a certain house, even though she could actually leave.
The red-haired gravity manipulator had to go out every day to look for his runaway house Zashiki Warashi.
During the Holy Grail War, a witch who could grant any wish made her public debut, competing with the crooked Holy Grail for work.
The people of Chaldea were delighted to see it.
Xing Jian Yue, whose true form was actually a mirage, hid back inside the wish shop.
The Hiyobo, Kagami Hime, and Zashiki Warashi you’re looking for...
It’s ko no Xing Jian Yue!
P.S.:
The heroine has many secret identities, but they all have the same face.
(Don’t be misled by the blurb. The heroine isn’t lively; she’s the very polite type who’s secretly dark-hearted.)
A steady power-up story. Her initial strength is nowhere near enough to dominate everyone.
It crosses over with lots of anime. Some characters have one-sided feelings for the heroine, but not everyone is romantically interested in her. She isn’t a “loved by everyone” kind of protagonist.
Theme: Run an honest shop and enjoy helping others
