What makes Katanagatari interesting isn’t because of its connection to Bakemonogatari’s author, Nisio Isin; it’s not because of the crazy antics the animation studio does (not exactly for some though) or how wacky the characters are (again, opinions may differ); then again, it’s not about the morality discussed in each episode, but more of it as a whole.
"The whole is greater than the sum of the parts"
And to poke fun with this phrase, I’ll start by questioning the elements themselves, namely the characters (only some though).
The show is obviously a story about swords, and when there are swords, there are swordsmen. Here, Shichika, a human, is a sword, symbolically-speaking, under Togame, the strategian. Shichika had been a very dull and uninteresting character at first, perhaps because he lived with his sister in an island, or maybe because of his father’s upbringing. Either way, he’s supposed to be a sword. Swords are objects, aren’t they? And as the 7th head of the KyotÅ-ryÅ« , he personifies a swordsman that doesn’t use a sword. Unsurprisingly, he develops a personality later on, or to be specific, somewhat of a mild change in his behavior – and it can be explained by his lover (haha) slash owner (again haha) Togame, and their travel around Japan.
It’s important to note that a single person can make millions of decisions under a myriad of circumstances in his lifetime. That said, who the person was the day before may not be the same person the next day, and that can be from external or internal circumstances that consciously and subconsciously change his behavior – in this series, Shichika changed because of Togame – I am, however, not stating that Togame is the sole reason though. I’m just saying that she’s a catalyst of some sort, and without her, Shichika wouldn’t even have a reason to leave the island. So, slowly, gradually, he’s changing—it’s an ongoing process. For Togame, it would seem like a change for the better. He’s still the type of person who’d kill a woman though, because he’s a sword and anyone in a battle field is generally an enemy. For Nanami, his brother’s change can either be good or bad. Her comment on him becoming dull/rusty (another sword analogy) can also be taken either way, in both being a sword, a human person, or even both. I may have never noticed it before but I think this was the first time Shichika cried. Yes, for the loss of a family member; but then again, if you objectively regard yourself as a sword, that meant something.
Speaking of Togame, her father was killed by Shichika’s father – and by working with her father’s killer’s son – it’s either a very bright idea or below-average stupid. Apparently, this was one hard decision for her. She doesn’t have many options though, and employing a person that won’t be corrupted by the swords and who she can trust because of love does sound like a win-win scenario, if not for their pasts. One can only imagine what will happen with the two in the end – if Togame will still use Shichika, or if she’ll throw him away. Nevertheless, one cannot forget her statement, “I don’t know about half a year ago, but you’re the only sword for me now!” If her reasons before were entirely objectively using him in her schemes, well, you can’t say the same by the recent episode. Her last comment in the episode bares it all: “ No family? Are you dumb…I have you and you have me, right?” You can take that statement either way, you.
Nanami… Oh, if I was frightened by her in the episode where she beat the crap out of the insect squad, I am now loving her. She realized that there was nothing left for her. She’s at the apex of all martial artists, and her defeat by her brother’s hands was a result of Togame’s trickery, her downgrading (not using Akutou Bita), and her own wish to be killed. Killing the family members seems to be common in the Yasuri family, but it sure is both a bittersweet kind of death, to be killed by a person close to you. All her actions, using sharingan *cough* to copy the skills of her opponents, were motivated by her own decision to end it all – to end her life. Sure, she could tell anyone that there’s no need for a reason to fight – but deep inside, all she wants is to escape her invincibility. Then again, she continuously gives her brother a reason to fight her (i.e. the deviant blade, cutting Togame’s hair). One could say that the weed finally got weeded out.
I won’t go specific on the Maniwanis. They’re all interesting in their own right. Some are just plain weird (i.e. Reverse-talk Shirasagi), others completely brutal (i.e. Houou Maniwa slicing his own arm and a fellow Maniwani just to be on the good side of Togame), and others I sympathize with (i.e. the whole Maniwani insect squad). I don’t even feel like discussing the owners of the deviant blades as well. Epic Hakuhei Sabi fight is epic.
The point being that the series showcases characters that are entertaining because they're humans living in a dog-eat-dog world--sometimes, they're even larger than life. Their motivations and circumstances may be different, but they still try to make do with what they have. They can be barbaric sometimes, but isn't that how human life was before, heck, even now?
I’ll end it with that. After all, the whole series is a parody, and the show keeps reminding us that. It can be good. Or it can be bad. You decide.
