Checked the bookwalker link and it seems like its only related to fabiniku because of the author?? I dont get it either since its all in japanese but it seems like the story is about this girl who wants to be an animator and make anime? Wish someone picks this up so we would know haha.
Wonder if Fabiniku would be referenced a lot here, how would the sister deal with the fact that her salaryman brother got isekaid and turned into a super cute short blonde teenager looking girl?
