I’ve talked before about how my desire to see the main six cast members live happily ever after is warring with the narrative, which keeps underlining how Oliver and Katie are doomed. With this episode, I get the feeling that we’re going to be adding everyone else to that list as well, and make this an All Or Nothing type of series. The two characters who have gotten the least focus get attention here, and while Pete is mostly setup for future volumes (with one huge exception which I’ll get to later), Guy’s arc is looking to be a lot more dangerous and potentially fatal. Generally speaking I’ve always thought of Guy and Chela as “the sensible ones”, and this book is here to throw that out the window and remind me that absolutely everyone in that group is weird as hell. Of course he survives – none of them will die till at least Oliver explains what he’s doing. But yikes, I don’t wish what he has to go through on anyone else… wait, absolutely the wrong way to put that.

Despite the fact that Guy and Pete get much more focus here, the publisher still knows who its big sellers are, so Oliver and Nanao are on the cover again, along with new teacher Rod Farquois, who will be taking over astronomy, is a reversi just like Pete, and absolutely no one knows what they’re up to – it’s very clear they’re not here at the school’s request. As for the main plot, half of it … again, we’re coming to it… but the last half of the book is a rescue arc, as Guy, Ursule Valois’ twin attendants, and forgotten first book teen bully Annie Mackley are trapped on the second floor of the labyrinth, which is dealing with someone consumed by the spell, and he’s turned the floor into his own cursed treehouse of horrors. Everyone will be going there to rescue Guy/the twins (sorry, Annie, no one really likes you), but can they do it before Guy makes an irreversible decision?

I hate to be a broken record, but my god this series is horny. It’s baked into the plot, as it’s hinted that one of the main reasons that our heroes are suffering so much right now is that they’re not banging each other on the regular. Pete, at least, takes care of that in one of the more startling scenes in the book, where he confronts Oliver in his female body and takes him to bed. Oliver, of course, is doing similar things with Nanao, and Chela helped him earlier. Katie loves Oliver, but knows he’s rejecting her, so is snuggling Guy every chance she gets. Guy likes Katie, so is helping her with this. Third-year Rita likes Guy too, and is angry at Katie. And we also meet Leoncio’s sister, a third year who is absolutely his distaff counterpart, and who seems to be constantly aroused. I don’t think that all Oliver’s problems would be solved with an orgy… unless?

This is another book that ends WHAM, no epilogue at all, so I’m not sure what happens next. The cover to Vol. 13 sure looks like a “Breaking of the fellowship” situation, though, huh? In any case, please read about these powerful and pent-up idiots.
