Ah, so this is what Kiriraitaa was sketching... high anticipation for what this will turn out to be. Although I hope it's not going to slow down his output already, with between studies...
We'll just have to wait for about another 3-4 weeks to find out. They're far too cute, if it's not abuse I'll be sorely disappointed. Although I get the feeling this might turn out to be a yukkuris going about doing their own silly things (and eventually something too stupid) rather than a direct abuse comic.
Kiriraitta's stuff is like, never family friendly. This particular picture may be but I doubt the series itself will hold up as a family friendly series.
It was just an accident, and it was only the komarisa. I will give up now on removing the dumbass tag unless the Marisa apologizes in the next page.(Unlikely, but it could happen.)
