Group of kos fighting off a larger yukkuri and succeeding? Damn, that's something neat.
Also would be awesome to know what this series is about. Seems mostly FF, but a few of the earlier pics are a bit abuse-y unless it's training or something. Sure is tl;dr though.
It reminds me of that scene in Selfish Reimu where the 3 komarisas are jumping on Reimu. If those komarisas weren't barely a day old I'm guessing this is what would've happened.
I just read through the "Selfish Mother" (I assume that's what you meant) tagged images to find what you were talking about and now I'm angry. Though I repressed that series.
