"But Hachikuji, trying to be clever can backfire. You don't want to get too convoluted in your approach."
I wonder just how aware Isin was when he wrote such a line. It seems this book, the second volume of Nisemonogatari, was released before the Bakemonogatari anime adaptation started airing, yet Isin seems to have predicted Akiyuki Shinbou's near-pretentious take on Isin's kinda-pretentious novel series. Not that I dislike Shinbou's style, but its abstraction sometimes borders on the cold, in comparison with Isin's more emotional approach to his characters (well, that's probably more true for Kizu- and the end of "Tsubasa Cat" - basically any Shinobu-centric material).
Also, holy shit, how could I have been so dense as to not notice the similarities between this series and Gegege no Kitarou, or specifically Araragi's anime design and Kitarou's?
Anyway, the Monogatari series holds a strange position for me, where I can see clearly that the novels are "mere" light novels, but I can't help but be drawn to the near-useless banter between characters. It seems bizarre for someone who puts so much weight into his interest in belles-lettres, but I suppose my excuse is that I just hate the "ideal" of Narrative so much I have no choice but to love when a book puts much of its focus on silly conversations, waiting nearly 200 pages before actually getting into the real plot (and even then the tried-and-true final battle characteristic of many a light novel is somewhat subverted with Araragi getting destroyed physically and ending the feud with the "ghostbusters" with a variant on a Touma monologue [as in A Certain Magical Index] - not that subversion in itself is always a good thing).
The highlight of this novel's banter, by the way, is Hachikuji and Araragi's discussion concerning the latter's character design for SHAFT's Bake- adaptation. Basically, we have finally come to the point where the "anime adaptation" jokes have reached their logical conclusion, coming to the release of the actual anime adaption. I am only now realizing SHAFT's constant delay of the Kizu- movies may have been purely an inside joke concerning how Oshino and Araragi were adamant that the latter's spring break could not be adapted properly into an anime.
Speaking of Kizu-, this novel suffers the same issue as its other half, with almost-egregious references to the players of that prequel novel. Bake- had a strange advantage in being written before Kizu-, so the reader got a hint that something hellish happened to Araragi over spring break, leading to his becoming a vampire, and subsequently getting near-cured by near-cursing his vampire assailant, but the details weren't quite ironed out. Nisioisin followed Bake- by realizing the ever-referenced prequel events into an actual concrete prequel. Afterward, he jumped ahead to the direct sequel to Bake-. The difference between Bake- and Nise- is thus: the newer novels were written with the assumption that the readers have encountered the vampire hunters Dramaturgy, Episode, and Guillotine Cutter. So now, what?, Isin has no choice but to make contrived references to those guys just to hammer into our heads that Nise- came right after Kizu- was released? Comparing Ononoki back to Dramaturgy works, I guess, since it justifies the series's inclusion of aberrations' metamorphoses, perhaps to show Ononoki's Unlimited Rulebook isn't just an absolute non-sequitir (of course, the Kizu- film trilogy's late release didn't help the anime, which really augmented the gravity of Tsukihi's supposed death).
Also, I have to say SHAFT did a better job setting up the Tsukihi-is-an-immortal-aberration-masquerading-as-a-human twist than Isin. Tsukihi, like her sister Karen, barely existed earlier in the series, appearing essentially as dual alarm clocks for Araragi in every episode's epilogue, without getting any real screentime otherwise. Karen gets adequate screentime in her own novel, but Tsukihi is unfortunately set aside in favor of more Karen screentime, as well as more banter with Hachikuji, and the setting-up of Kagenui and Ononoki. Shinobu then grabs the novel's focus by mimicking Karen from earlier in the book, and Kaiki comes back for a significant portion. By the time Araragi gets back to his house, Kagenui and Ononoki are already there, waiting to kill Tsukihi, an event which occurs almost immediately upon her opening the door. At least the anime made us care a bit more for Tsukihi with the PV for that extremely cute "Platinum Disco" OP, infectious enough that I skipped classes back in 2012 the day I reached the "Tsukihi Phoenix" part of the Nise- anime, simply so I could get more of that kawaii head bob she does in her little dance.
And really, good job trying to end your series by introducing two more ghostbusters like Oshino (I mean Kaiki in "Karen Bee" and Kagenui in "Tsukihi Phoenix," the ending of the series being Nise- overall, though I suppose it still works to say Kagenui and Ononoki are two ghostbusters in this novel, specifically [and even if not, Kaiki isn't noted to be an acquaintance of Oshino's until this book anyway]). Of course, chronologically speaking, this is the end of my experience with the Monogatari anime (I've seen Neko- [Kuro] and the Kizu- films, which were released later, but were set before Nise-), so I don't know just how important/relevant Oshino's friends might be later on, other than that Kaiki returns at some point, and Ononoki gets a "Yotsugi Doll" episode, meaning she's guaranteed a return, even if I don't know whether Kagenui comes back herself.
Lastly, I'm now in limbo with this series, w/r/t Araragi's harem and the question of Best Girl. For whatever reason, I strongly disliked Hanekawa when I watched the Bake- anime, and, while I don't remember much of her character in the Nise- adaptation, I do recall not getting into the Neko- (Kuro) episodes simply because they were Cat-centric. Hell, I don't remember the events of that subseries at all, aside from Shinobu's sword and the animation going into overdrive when Shinobu fights Black Hanekawa, with the fanservice shot of a bandage covering Shinobu's loli vampire pusi (I don't care enough to deflect why I might have remembered that scene, though I will use the partial excuse that the animation itself finally seemed worthwhile after a long time of monotony). But anyway, my point is that the Kizu- novel made me appreciate Hanekawa a hell of a lot more. Then the events nearer to the end made me appreciate Heartunderblade/Shinobu as more than loli fanservice. I loved Tsukihi mostly because of her theme song, and I liked Karen mostly because of the toothbrush scene, so my enjoyment of the Nise- anime was perhaps disproportionately higher than that of Bake- or Neko- (Kuro) (though by now I like Kizu- the most, from what I've seen). Hanekawa is essentially absent in this volume (aside from connecting Araragi's cram school with Kagenui's destination) and Shinobu is almost completely different from her original character (though at least she acknowledges it), so I'm back to not knowing who I like best. If I'm not mistaken, I think Nadeko was my favorite from the Bake- anime, and I guess that still kinda holds true since I'm more than fine with the shy "nadeshiko" types, and of course Nise- makes her more interesting with her sneaky attempts to seduce Araragi under the guise of her alleged childlike innocence, but I don't know. It may be safest to just crown Hachikuji with the title of Best Girl, at least for now. Hopefully I can give myself a more concrete answer upon reading the Neko novels. It might be a pain if I have to keep reading every installment before I can determine Best Girl, but whatever, I'm gonna read 'em all anyway.
Postscript: I can overlook translating honorifics and ruining the ideas behind common usage of "onii-chan" and "nee-chan," but the fact that they used "animes" as the plural of "anime" just crosses a line. Too many memes, man.
