Pathetic doesn't come close to describing the atrocity of this. Have you seen those one-second glibs that are looped for five minutes? Yeah... Every damn sex scene. Plot? What plot? Characters? What characters? Oh, you mean those dolls that are having sex. It's the creativity of a boy who has just discovered what sex is and has stolen his sister's barbies and is crashing them together in the imitation of sex. Don't bother watching it. Not worth it. I would give a worse rating if I could.
Plot? The end of the world. Whoops nevermind, it's not happening.
Why is there a minimum requirement for a review? What more can I say? The characters are none existential. The anime treats rape in the same way they always treat it in hentai. Like it isn't rape. It's the "oh, no, don't do it," in the driest tone possible. What was the budget? Did they even break even?
