I wasn't able to sit down and post here while the show was airing, but I think I remember a post whether from pixiv or twitter. maybe Japanese, that said Shiiko Sugai was some fan of 70s animation designs getting vindicated, or that it was the kind of porn that waited 40 years to be mad.
That post made me believe she was some background character from 0079 (given her beady eyes). Anyone heard something similar during May?
