If there's one particular 'something' that makes NisiOisiN one of my favourite authors, it's how he writes everything around one particular focal point for each of his tales. It's like a black hole, sucking everything around it in.
I was originally torn by both Nisemonogatari stories for going more off-course than every novel before it, but Onimonogatari takes the metaphorical cake, runs away with it, does a u-turn, and smashes you in the face with it (after, of course, trying to get someone else to buy said cake for a profit but being turned away at every corner because no one wants a cake that's melting before your eyes). To continue the metaphor, as NisiOisiN surely would have wanted, I still think that cake with the sloppy frosting tastes better - or at least much rawer - than a cake that's kept artificially cold.
When you take out that cake that's been frozen in time and take out the knife, you realise just how cold and hard the refrigerator has been keeping it. It's not that it takes that much away from it originally being a delicious cake, but I definitely would have preferred having a slice of cake that's quickly melting away in the eat. Even if I don't get to have quite as many slices. Keep a cake in the refrigerator too long, and it'll become something that barely resembles what it was in the first place.
Its taste; its flavour; its essence; it's been sucked into the void and become nothing.
But we're getting off-track here. This review's meant to be about Onimonogatari - I realise that, so please hold off on the criticism until you've reached the end of my review. If it manages to reach an end, that is.
We're reaching the end of the Second Season, with only one conclusive volume remaining. Onimonogatari fills in the gap of knowledge surrounding what happened concurrently with Araragi while Hanekawa was busy dealing with her Tiger. NisiOisiN's done a prequel tale, a mid-quel tale, two false sequels, a far-flung future pseudo-epilogue, a far-flung tale of the past that starts in the present and ends exactly where it starts, a tale that has yet to end, and a tale that takes place at the same time as another tale that changes the perspective. You can never fault the author for not playing around with plot devices and story setups as creatively as possible to keep his loving audience hooked. I, for one, was reeled in hook, line, and sinker.
Onimonogatari is something of a return to form. It's serious and focused on Shinobu like Kizumonogatari, exceptionally frivolous like Nisemonogatari, and a very laboured return to what defines the existence of abberations. This is a history lesson as much as it is a gripping tale full of light-hearted humour and devoid of light. Araragi once again takes the reins, but he's predominately re-telling Kissshot's long-lost tale of darkness. More than half of it is the tale of a cold-blooded, hot-blooded and iron-blooded demon. It's a tale that gets so far off-track, misses the mark, and avoids the issue that every character - no, in fact, even the audience - loses their way.
This is easily one of the best tales in Second Season for its great comedy, narrow focus on characters, and long-winded reprisal of what made Bakemonogatari and Kizumonogatari so great. It's a story full of the best twists and turns - not because you don't see them coming, but because, after so much time, you can't help but see them coming. NisiOisiN is ruthless with the Monogatari Series' continuity, which allows him to revisit, reinterpret and flat-out pervert what has come before. And this tale is just that; it's a retelling of everything that has come before engulfed in darkness.
Onimonogatari is the tale of a demonic deviant and a contrived falsehood. The foreshadowing is just as wickedly in-your-face as every tale before it, and you'll kick someone for not picking up on anything. It's diabolically eloquent, hauntingly dark, and fiendishly roundabout.
It has just about everything you could ask for in the freshest iteration of the Monogatari Series.
Except Senjougahara. Sorry about that. Next volume, maybe?
