Ada's dorm assignments and Explanation's and a bit of Headcanon's under ⤵️
HEARTSLABYUL
Atsushi: I was struggling with choosing between Heartslabyul and Savannaclaw for him. I think Savannaclaw would fit better (the tenacity part, and the tiger thing), but in the end, I chose Heartslabyul because he values justice, responsibility, and doing what’s right, which fits well with the rule-oriented nature of Heartslabyul.
Kenji: I chose Heartslabyul mostly based on vibes. Kenji is a cheerful and easygoing person, but also has his own unique logic that feels like the chaotic side of Heartslabyul.
OCTAVINELLE
Dazai: I don't think much needs to be said… His charisma? Cunning personality? Talent for manipulation? Straight-up Octavinelle student, no question asked. Especially with how easily he reads people, charms them, and manages to make people do what he wants by smooth-talking.
Haruno: This was a bit of a challenge to choose for her. At first, I thought about Pomefiore, but we already had so many characters in there, so I decided against it. I also considered Savannaclaw and Scarabia, but they didn't quite fit. In the end, I stuck with Octavinelle purely because of Haruno's intellect. It also felt right to make her a vice housewarden in her dorm.
POMEFIORE
Kunikida: This choice was easy, just like Dazai's. The drive for perfectionism, discipline, and ideals—he’s the literal embodiment of Pomefiore. It felt perfect for a dorm that’s known for its image-conscious students. It also made sense to make him Housewarden (and a little poke at the fact that, in canon, he’s supposed to take over as head of the ADA).
Junichirou: I was heavily influenced by his gentle yet thoughtful demeanor and the protectiveness he shows (not only his obsessive care for Naomi, but also his willingness to stand up for others). Despite being a bit of a wimp, he’s protective and supportive. He’s also a vice housewarden to Kunikida.
Naomi: To be fair, I had a hard time choosing for her. At first, I thought maybe Heartslabyul would be good for her affectionate yet mischievous personality. Then I considered Octavinelle for her cunning and strategic side. In the end, I went with Pomefiore, blending her elegant and calculating nature. She’s charming, and her subtle manipulation would suit the dorm well. It also helps that Junichirou is here, as where he is, Naomi is likely to follow. But I do think she was probably in Octavinelle first and switched to Pomefiore less than a month later.
IGNIHYDE
Rampo: Another easy choice. He’s intelligent and prefers solitude, plus his amazing problem-solving fits Ignihyde perfectly. He’s brilliant and often dismissive of what he considers unnecessary social interactions, so this is 100% the right dorm for him.
DIASOMNIA
Yosano: Diasomnia is a very fierce dorm, often associated with strength, authority, and a commanding atmosphere, which perfectly suits Yosano. Not only is she fierce and strong, but her role as a housewarden also fits well with the dorm's atmosphere.
Kyouka: She’s resilient and carries strength with her despite her tragic past. As previously mentioned, Diasomnia is focused on power and overcoming inner turmoil (especially considering the storyline of Book 7), so it’s a great fit for Kyouka.
Diasomnia overall is just a perfect choice in that regard for both Yosano and Kyouka.
I might also do other organization's in this AU if I feel like it, haha
Or maybe I should do it the other way around? TWST in BSD universe???
