In the original story, a poor hatmaker took pity at some Buddhist statues and gave all of this hats to them.
The Buddhist statues come to life that night and repay his kindness with food
In this story, Marisa's kindness is rewarded with rape. Which I supposed could have been what Marisa wanted all along... Then again she's not a whore like Reimu
Regardless, those statues were actually Alice statues. And nothing good comes from Alice being anywhere near Marisa.
