Sorry to necrobump. I have a theory: This Reimu is a shithead from the start, but anon punishes her usually, so she finally turns into normal head (between nice and shit). She gets angry because none looks like her, a typical sign of deibu - who kills kos. It should be noted that giving toys right after punishing your yu pet is pointless.

But for some reason Reimu has an even uglier face than usual.
Having a sudden bad feeling, I go to the study to check up about Reimu type, not wanting to do a blunder like with the seedless Marisa.Marisa and me overjoyed by the kids' birth.The shky!Because the sperm paste contains a lot of fluid, as expected, the ones born are a nonchalant Maricha, a crybaby Maricha, and a hyperactive Maricha, 3 of em.
