Also posted on AO3. I once had this planned as an AU, but I recently realized the worldbuilding works a lot better as headcanons. Ive sat on these for a long, long time because of the discourse with She Who Shall Not Be Named. I do not mean to bring up painful memories for anyone, I just wanted to have some fun in a world Ive enjoyed over the years.
Nobunaga is always interested in learning of technology, information, and ways of life beyond the island of Japan. He wants to know as much as he can from the Potuguese traders. While Nobunaga could also be a Slytherin for his desire to dominate Japan, in a world where magic exists and he is not fighting the wars of the Sengoku, I think he would be more interested in learning than in fighting. Therefore, I have put him in Ravenclaw.
Gryffindor is a simple choice for Hideyoshi. Always upright, just, loyal, and self-sacrificing, he is a classic fit. And he’s the most likely to have a grudge against Slytherin's methods.
I put Masamune in Gryffindor because of his headstrong, charge-first-ask-questions-later attitude. I think it's a very Gryffindor trait. Out of the warlords in Gryffindor, I think he’d be the most likely to have a bunch of Slytherin friends; he doesn’t judge on house but on ability, and Slytherin are certainly a capable lot. He often ends up the victim of Hideyoshi’s chastisement over his choice of friends.
Ieyasu’s motivations in his own route focus on power. He has been powerless in the past, as a hostage of the Imagawa. And he never wants to be in that place again. He wants to prove his ability, and be stronger than those who have oppressed him; never again to be the victim. For this reason, I think he’s a Slytherin, as opposed to a Hufflepuff. Who's to say you have to be a Hufflepuff to like plants and healing?
This one was easy, as we all know Mitsunari’s propensity to get lost in a sea of books. I like to think that he reads so often that he entirely forgets to attend class. The professors have tried to have him reprimanded for this but as he always knows so much more than the other students, Mitsunari manages to get away with his behavior.
Sneaky. Slippery. Secretive. These are all things that describe Mitsuhide and Slytherins. He respects the order of Slytherins, but also fights it. He occupies the darkness, the space behind everyone’s backs, never admitting what he is really up to. He embraces this dismal role to protect those outside of its clutches, much like other well-known Slytherins have done--or more appropriately, have been forced to choose. I think Mitsuhide would be mighty good at potions, as well as a skilled duelist.
Kenshin is noble, honorable, and will stand by what he believes is right regardless of what other people try to convince him to do. Both Slytherin and Gryffindor like a good fight, but because of Kenshin’s upstanding values in a fair fight, he wouldn’t play dirty the way a Slytherin would. Thus I think he’d be one of the few Gryffindor’s who actually followed the rules, haha.
Shingen - Gryffindor / Ravenclaw
Shingen… this one is one of the hardest to pin down for me. I think he has traits of a Gryffindor in the loyalty to his land and to his people. But also traits of Ravenclaw in his tangled web of information which he manipulates like a well-trained puppetmaster. I guess that gives him a little bit of Slytherin aspects too. Though I don't think Slytherin would be a good fit for him though, as he desires power not for himself but for the people. Therefore I’m going to say he leans a bit more Gryffindor than Ravenclaw, but he could really be either.
I imagine Yukimura is the Quidditch captain of Gryffindor. He already wears red, so its not that much of a change for him. He’s active and sporty, but yet respects the rules and the right thing to do. Most of the time. We won't talk about that one time out in the woods, he’s not proud of it either. Overall, like Hideyoshi, I think Yukimura is a pretty classic Gryffindor.
How could our astrophysicist ninja be anything but a Ravenclaw? The amount of learning, innovation, creativity, and tenacity it takes to track wormholes without the equipment and technology of the modern day is astounding. Let alone the sheer amount of math.
Kennyo is a big, softie and you can't change my mind. He loves all the things Hufflepuff stands for: hard work, nature, animals, kindness, etc. Kennyo won't hurt a fly if given a chance, and nor would a proper Hufflepuff. He embraces the common man, and rejects the racism of Slytherin, the elitism of Ravenclaw, as well as the arrogance of Gryffindor. Kennyo is the epitome of a Hufflepuff.
Ranmaru - Hufflepuff / Slytherin
Ranmaru is a strange one to place because he is a ninja of many secrets, loyal to opposing sides and stuck in the middle. I think he wants to be free of the tight-rope he walks daily, and if he is, he would likely embrace the philosophy of Hufflepuff in order to keep other people from being stuck in the same painful position he had been in. I also think he would make a damn good Slytherin.
Yoshimoto is interesting because his love of the aesthetic and art would seem to place him in Ravenclaw. And yet his desire to do nothing, to live out the remainder of his days in quiet obsolescence, can also be very Hufflepuff. They’ve cornered the market on cottage-core, after all. He desires to be left alone to admire the things he finds beautiful. I picture him kinda like the curator of a small, private museum. Ths collection of things are the beauties that give his life meaning, and it doesn’t matter if it's just a strange mushroom. He doesn't want to be bothered by anything else. He’s a rather eccentric Ravenclaw, who can be found admiring unnoticed artifacts in the castle instead of attending class. He’d get more detentions, but too many people are so entranced by his own beauty that they forget what they were upset with him about. He’s quite proud of how proficient he is with that charm.
Motonari was almost a Gryffindor for his utter disregard for the rules. But I think his “watch the world burn” mentality fits into Slytherin more. Slytherin likes order to Motonari’s chaos, but I think it's the place that is most conducive to his out-for-no-one-but-myself attitude. I imagine that he’d be on good terms with the Bloody Baron, and there are stories after he graduates akin to the horror stories told at teenage sleepovers created about Motonari’s school years.
