Looking at the child post and the parent post, I'm not sure if it's actually Tewi without her rabbit ears, or the child post is Yukari with rabbit ears.

The child post is tagged Tewi but looking at the posts, I think it's actually Yukari with some rabbit ears on.

I'd agree, but for the changed eye color & the carrot necklace; these changes seem to indicate that the child should be tagged Tewi.

ゆかりんの薄い本がほしい。 ２枚目はお遊びです

I want a doujin of Yukarin.

I made the second post just for fun.
