I’m very fond of the Sorting Hat Chats. Their system divides houses into primary and secondary houses. Primary houses are why you do what you do; secondary houses are your methods, the how. They’ve got big essays over there on each house’s qualities for primary and secondary. I like them a whole lot, and they haven’t put up any new sortings lately, so I’m going to sort Library Wars. (This is based on the manga and a fan translation of the original light novels; I haven’t seen the anime, and I only saw the live-action movie once and haven’t been able to find a version with subtitles again. Also, while the live-action movie was awesome, it necessarily left out a lot.)
Unsurprisingly, the Library Force has a lot of Gryffindor in it.
Iku Kasahara is a Gryffindor primary. She knows intuitively that censorship is wrong, and so she’s going to fight it. She decided that very suddenly in high school after her first run-in with the Media Betterment Committee, and having decided that, she immediately devotes her life to doing what is right. That moral certainty is the real reason she’s the first woman assigned to the elite Library Task Force, because while they can (and do) train the bookwork skills into her at least enough to be up to par, they can’t train the devotion to the ideals into her. She finds the world very black and white– no matter how many times Dojo and Genda tell her “We’re not heroes”, she persists in believing that they are supposed to be heroes. Often enough, when she’s flinging herself against reality like that, reality is the thing that ends up shattering.
She’s also a Gryffindor secondary. When confronted with another bookstore in need, her first impulse is to go charging straight in without any awareness of what her actual authority is, because if censorship is wrong, it must be stopped by the most direct means possible. She breaks the Library Force’s rules without a second thought if it means doing what’s right, and when she’s prevented from doing so she rails against the injustice and insists politics should play no part here. We see her Gryffindor charisma pulling everybody else in behind her– Dojo takes punches for her, Komaki breaks his strict radical honesty with a lie of omission to protect her, and Shibazaki, who decided long ago never to have real friends, wants to be her friend. Even Tezuka, who initially can’t stand her, also can’t stop thinking about her. She’s rapidly acquired an army of people who will follow her lead, to the point where Dojo is willing to take risks that nearly get him killed rather than let the impossible odds against them stop them from doing what’s right, all because she’s inspired him.
Dojo is also a Gryffindor primary with a Gryffindor secondary. Like Kasahara, he knows intuitively what the right thing to do is. Censorship is wrong, and while we don’t spend a lot of time in his head, we do know what was going through is head in the bookstore– hurting a high school girl over a book is also wrong, and most of the people advocating censorship are brutes. Unlike Kasahara, though, he’s buried his Gryffindor/Gryffindor under a Hufflepuff/Hufflepuff model. He tries to base his actions on his loyalty to the Library Force as a whole rather than the broader intuitive “censorship is wrong”. He tries to accomplish his goals via working hard at his assigned duties, training the recruits, and being the best Task Force member he can be. Part of the problem he has with Kasahara is that she calls out to his buried true nature, and by the end of the fourth book he’s choosing to rewrite the plan on the fly so they can complete the mission in the face of impossible odds– and he nearly dies doing so, and doesn’t regret it, even when by regulations he should probably have gone back to base. Together, Dojo and Kasahara kind of become Gryffindor squared, and no reality cannot be bent to their will if they try hard enough.
Hikaru Tezuka is also a Gryffindor primary! He has that same intuitive sense that censorship is wrong that Kasahara and Dojo have. It’s just Tezuka expresses it differently, because for him, it’s personalized in the context of his brother. He never cites any reasoning the way a Ravenclaw primary would when arguing with Satoshi– it’s just “You are wrong because censorship is always wrong and you’re manipulating me which is also wrong, and also you’re hurting our parents!” He’s willing to turn to Satoshi when it serves the ultimate cause by finding out where Komaki is, but he won’t try to get Satoshi to stop coming after Iku– because he knows the price for that would be “betray all your ideals by helping me”, and even to save a friend he won’t betray his ideals. (This is, in fact, Tezuka’s core problem with Satoshi: Satoshi ostensibly has some kind of complex plan to accomplish the same goals, and Tezuka’s straightforward Gryffindor nature sees this as unworkable. You know what’s right, and you do it; the very idea of a ten-year subterfuge is ridiculous and will never work.)
Tezuka’s secondary is Hufflepuff. He lives his ideals by joining the Library Force, excelling at both the bookwork and the training, working hard, and trying to live up to the family name.
Komaki is the only one on Team Dojo with no Gryffindor in him. We don’t spend a lot of time in his head, but we do see that he’s consciously chosen a lot of his behavior, like the whole “I only tell the truth” thing, which he’s still willing to bend when faced with evidence that in this case it’s right to make an exception. He’s also the one who’s most rational and observational about everything– the one pointing that yes, Library Force politics do exist and we need to account for them, and quietly talking everybody else through their emotions with his rationality. (Even when Marie is hurt, he’s able to tamp down his rage and use it, and think to have Iku test his hypothesis about why Marie was targeted.) That makes me designate him Ravenclaw primary, one who’s decided on the values of the Library Force to guide his system.
Komaki’s secondary is Hufflepuff, but he expresses it very differently from Tezuka. Where Tezuka works hard at the curriculum and his duties, Komaki builds community with the other officers– he’s there to comfort Tezuka after the bear-killer incident and Iku after she finds out the identity of her prince, and more generally Komaki is usually the one explaining everybody to everybody else and quietly keeping the team stable. He’s not obvious about it, but he’s always there when it counts.
Shibasaki starts the story as a petrified Slytherin. She wanted friends, in middle school, but middle school was so awful for her that she cut herself off from the possibility and tried to care only about protecting herself. I say Slytherin and not Hufflepuff because she doesn’t feel guilty for not caring about the people around her; she’s just lonely and trying not to admit it. When she meets Kasahara, she gradually starts to un-Petrify and realize this is someone she wants for a friend, and then she pretty much wholesale adopts her, whether that means teaching the library classification system or openly sticking by Kasahara during the inquiry. Later on she adds Tezuka to her people. Pretty much all her actions after that point can be defined by her own personal ambitions (being a good librarian and rising through the ranks) or standing up for Kasahara and Tezuka.
Shibasaki’s secondary is Hufflepuff but with a solid Slytherin model. When push comes to shove, what she relies on is her community connections and the effort she puts into being popular, but she’s also quite adept at improvisation and manipulation. The combination is what makes her so good at being in the library’s intelligence division.
Genda is harder because we see him less often and almost never as a POV character. He could go either Gryffindor or Hufflepuff, or even Slytherin– I’m not sure if he’s charging into his ideals because those are his ideals, or if he’s loyal to the Library Force itself, or if Inamine and Origuchi are his and he’s loyal to the Library Force and freedom because those are their goals.
His secondary is Gryffindor, though. When it came down to the pressure moment, he stood up, blocked an artwork with his body, and dared the would-be censors to shoot him. We later find out that he was shot 23 times. How much more charging into things can you get?
Satoshi Tezuka is a Slytherin primary. First and foremost he wants power for himself, and he also wants his brother under his control. He’s got a somewhat corrupted version of it, though, because he puts the possessiveness before the caring– he doesn’t really care that he’s upsetting his brother; he just wants Hikaru to be his and he’s willing to set anything in train if that happens. He’s also got a Ravenclaw model, with his systems and analyses and examinations of the world– he achieved his views through study and examination, and he’s very smart.
His secondary is also Slytherin, improvisational, but with a strong Ravenclaw model. These two secondaries in combination result in Chessmaster tendencies, which he totally has. For most of the story, he’s operating on a long, complex plan that’s supposed to take ten years to play out, but when circumstances present him with a way to accomplish his goals much faster by allying with the Library Force, he’s quick to drop the old plan and pick up a new one.
Marie and Inamine we just don’t see enough of to sort, although Marie is possessive enough of Komaki that I would be unsurprised if her primary was Slytherin. Winning him seems to have been her driving motivation for most of her life.
