If you tagged “Futanari” because you think Page-36 is a female futanari then you got it wrong. The blonde bunny “girl” there was actually Aoi Toori the male MC, he was only cosplaying as a girl and to not to be confused it is purely costume without any gender-bending elements or such. The boobs were just accessories within the costume.
You can read the Light Novel volume in which that bunny “girl” appeared as its cover if you need a prove.
