Great English translation for most of the time (except for onomatopoeias), very, very decent artwork (albeit suffering a lot from heavy censorship - why even bother drawing a ridiculously enlarged clitoris if it ends up as as mosaic blur?), idiotic predictable story about yet another valiant female virgin knight/princess/priestess/whoever who turns out to be a worthless sex toilet and broodmother in one at heart and all it took to discover her 'true' calling was a month or two of constant rape utilizing loads of really deranged fetishes (though we've all seen them before somewhere else) and a pointless format of a virtual novel. This would have been so much more fun if it was an actual game, whereby the player would've had control over the progress of corruption/training and thus could decide themselves which content and how intense they want to see. This could also mitigate the rapey overall flavor, though I am aware that the non-consensual theme is exactly what some lewd game fans are looking for.
3/5
