Oh this is quite interesting. I don't know if its by the same guy that did the donuts series with the creepy lion guy... but this just tied up the 2 separate(?) stories.
So the story so far: father marisa (pet) picks up a trash reimu, gets her preggers and then tossed out of their house by mister. Then reimu forces marisa to steal donuts, and then another mister catches them while reimu runs off. Father marisa's story is shown in previous images.
The reimu in the doughnut story gets killed and then the ko-reimu is tossed out, and appears in what we see here.
Little marisa is wandering around and stumbles upon this reimu, what will happen remains to be seen.
