A FemAnon is eating lunch in the park. A stray Reimu comes up to her, says she's about to give birth, and demands a birth celebration (i.e. gifts). Reimu rolls over and starts to give birth, demanding that FemAnon catch the babies.
A baby Reimu starts to come out, demanding that the whole world celebrate her birth. FemAnon pokes her with a chopstick, then holds a toothpick up to her and tells her she'll be stabbed if she comes out. She tries to go back inside, but the oblivious mother forces her back out. The toothpick punctures the baby Reimu, and she cries about her lost virginity. When FemAnon pulls out the toothpick, the pressure of the mother's birth canal squeezes all the bean paste out of baby Reimu through the puncture wound. The baby falls to the ground and dies, a withered, empty husk.
Next, a baby Marisa appears in Reimu's gaping mamumamu, also demanding that the world celebrate her birth. FemAnon moves the mother yukkuri (who doesn't notice, concentrating on the birth), repositioning her so that when baby Marisa is born, she goes flying straight into a trash can. One of her eyes pops out, and she's throwing up bean paste. FemAnon tells her that she's garbage and that nobody will celebrate her birth, and the baby dies.
The mother Reimu is wondering where her babies are. FemAnon points out the dead baby Reimu behind her, and says, "Too bad, that means there won't be any birth celebration." As FemAnon starts to walk away, Reimu demands sympathy gifts. Instead, FemAnon picks her up and drops her into the trash, making one of her eyes pop out and crushing her feet.
FemAnon says that it's fun coming to this park every day because of all the different stupid yukkuris she meets.
