Traveling through Gensokyo, but the system is a Jujutsu Kaisen?

In Gensokyo, there is a Jujutsu Kaisen system, and all the abilities in Jujutsu Kaisen are available.

Just when Xiangbei thought he could punch the Red Devil Kindergarten, kick the Forever Nursing Home, and live a carefree and peaceful life, he found that something was wrong with the Gensokyo he traveled to.

Why did Alice have another daughter, and she was called Aika?

Why can Rumia become big, and Reimu has an adoptive mother who calls her grandma?

Why is there a girl named Yakumo Kurenai in the hidden historical traces of Gensokyo?

It's far more than that. The deeper Xiangbei goes, the further he finds himself from a peaceful life...

And, isn't this stitched fan fiction Gensokyo a bit too much? !

(Doujin flow, third-creation or even fourth-creation works that stitch together a large number of fan fictions, will have plots of similar worlds.)

(Doujin works that have been stitched together include Gensokyo Players, Gensokyo's Little Gods, Touhou Young Reimu and Reimu)

(It is expected that the more well-known Touhou fan works such as Renren's Bizarre Adventure and Touhou Alien Village will be stitched together)

(If you have to say, Gensokyo Players actually accounts for a larger proportion)
