I gotta admit that this is a new approach and a clever alternative to the usual 'bald guy/mannikin' type OC most others use. The use of dark figures silhouetted against a pitch black background is unsettling, yet titillating at the same time. It allows us to see "just enough" while leaving the rest to the imagination, helped largely in part by the sex positions used for each scene and how they're framed against Asuka's body.
I'm also appreciative of the fact that her figure wasn't exaggerated. She looks exactly the way she's supposed to: slender, yet still curvaceous with long legs and those perky B-cups. Favorited and 4-stars.
