Wait, what happened?
Reimu's getting anally reamed by the Nightmare from Little Nemo
And then Marisa's feared prediction came true.
With a splat, Reimu's filling came flying out of her stomach with a loud splatter. Within the filling a small ribbon and hat, some teeth and an eyeball can be seen. The little ones have died before they were even fully grown, this much is for sure.
"AH AH AH AH!!! LIDDLE ONESSSSS!!"
Marisa gave a terrified scream.
Reimu gave a crazed scream. Reimu's crazy acts must be stopped.
"Hang in there!! Deibuuuu!!"
Drawing strength from deep within her, Marisa flew towards Reimu for Reimu's sake.
