>>2631425I should add that sheet is from Noukin (see
>>2616637)
In which the writer and artist struggled with getting some more ecchi stuff passed the "OKing" process.
See the translated note from pic rel.
>>2616637 Is from a bonus, which I assume is how they got away with it.
Pic rel was as far as they could push it in the LN's. The good thing is the artist (Akata Itsuki) also draws H material so he has no problem draw ecchi stuff like for exmaple, Mile usually wears bloomers, but in some of the promo art you can almost see a part of her butt, implying she's not wearing any panties.
