Truly absurd. Say you're a girl (Hatsuki) who has a crush on your sister (Hatsumi) and one day choose to sneak into her room and just have your way with her as she sleeps. The next thing you know you're spanning parallel universes comprised of/represented by different storybooks on things like the Trans-Siberian Railroad, primeaval cultures, ninjas, desert islands, and god knows what else while accompanied by a pervy embodiment Lilith, to realize that your beloved is actually Eve, and exists for her own reasons in these parallel worlds and has many forms and loves. Throw in a batshit crazy fairy prince (Gargantua) who is a parodyof every "heroic" bishonen lead and his twisted reality involving a Princess, Mariel, whom he sacrifices only to watch a close friend, Ritsuko take the blame and punishment for him... Also a Kitsune woman with really large tits and her own censorship circle over her naughty bits.

This is a beautiful mess of intertwining characters, random story arcs, all set to Hatsuki's quest trying to find Hatsumi/Eve--both driven by an eternal love and guilt. It's as weird as anime gets, but still manages to make sense while doing it--to some extent. All of the charcters seem real, driven by real emotions, like Eve, whose flippant desire to span the worlds of books leaves broken hearts in her wake and dooms those who have fallen in love with her to search her for eternity. Hatsuki and Gargantua are two such people, each with their own goals and desire for redemption (albeit Gargantua's is superficially absurd, a more touching motive is told through Ritsuko's backstory). Even the pervy Lilith, who despite wanting to molest Eve, doesn't want to be left alone to be the custodian of the library for all eternity while her sister plays with the hearts of others and leaves her to clean up the mess.

It's weird, disjointed, introduces random characters from the parallel story arcs and breaks up the story line--but it all seems to work in spite of it all (with a surprisingly clear premise, motivated characters, and resolution) and makes for an entertaining way to kill an evening.
