MHA-Specific Den Headcanons
If you haven’t seen my previous post explaining what a den is, here’s the link.
Kirishima Eijirou: Kirishima loves his den, and is quite protective over it, though not as violently as other alphas. If someone tells him they like his den, it’ll lift his confidence for a week. If someone he doesn’t consider a packmate comes in, he’ll start growling immediately, but they have a few seconds to escape before he tries to attack them.
Todoroki Shouto: Growing up, his den was the only spot he was sure his father wouldn’t go in, as Endeavour wanted his alpha instincts to be as strong as possible and forcing yourself into a young alpha’s dens can weaken their territorial instincts. As a result, Todoroki has to feel completely comfortable with someone to even entertain the idea of letting them inside, as it is the one place he always feels safe in. Anyone who comes in uninvited will not escape without at least one serious injury.
Iida Tenya: Iida comes from a family of betas, and his parents weren’t very respectful of his den in his childhood; not purposely, of course, but their ignorance of alpha instincts resulted in too many mistakes. As a result, Iida has never felt like his den is his space, which is their entire purpose, and his den instincts are non-existent outside of his ruts, where they’re very weak.
Yaoyorozu Momo: Momo loves decorating her den, her obsession over needing it to look “perfect” rivalling an omega’s nesting instincts in heat. Her territorial instincts are weak enough that anyone she has even remotely positive feelings for can enter, but it’ll destroy her if they say they don’t like her den, whether she’s trying to court them or not.
Shoji Mezo: Shoji is a minimalist, not super concerned with what few belongings he possesses, and his territorial instincts are almost non-existent. He barely ever feels the urge to scent his den outside of rut, and pretty much anyone can walk in without a problem.
Jirou Kyouka: Like Iida, Jirou’s parents are both betas, and that resulted in some errors in her childhood, though not to the degree Iida’s did. Jirou is very self-conscious about her den and how it looks and smells. She isn’t very territorial, but she’ll get flustered whenever someone sees her den and will quickly try to get them out due to embarrassment.
Satou Rikkido: Satou, being the people-pleaser he is, tries to keep his den as pretty as possible for any visitors, and he makes sure to keep his scent of dark chocolate soft outside of his ruts. He doesn’t like letting other alphas inside if they aren’t a close friend of his, but almost any omega and beta can come in without a problem.
Kendou Itsuka: Kendou is pretty relaxed as far as alphas go, but that does not apply to her den. Her cedarwood scent makes the room smell like a sauna constantly, and she’ll fuck up anyone who comes in. Monoma once walked in accidentally, and the event scarred him for life.
Tetsutetsu Tetsutetsu: Tetsu fits every stereotype about alphas with their dens. He scents the living hell out of it, will attack anyone who comes in, and will have an emotional breakdown if an omega he’s trying to court says they don’t like it.
Shinsou Hitoshi: Shinsou isn’t too big on scenting, but he is quite territorial over his den. Someone has to have serious friendship points to be allowed in without being told to throw themselves out his window.
Yorashi Inasa: Yorashi loves fresh air, so his den has plenty of windows he keeps open almost constantly. Unfortunately for him, this washes his scent out of the room, forcing him to scent the room daily to have any hope of it smelling enough like him to be satisfying.
Yagi Toshinori | All Might: during his time as a hero, he was too busy to properly set up a den, as he was constantly moving from city to city to fight crime. He’s trying to get back into the habit now that he’s retired, but it’s been so long that he barely remembers how to.
Yamada Hizashi | Present Mic: Hizashi is pretty chill with all of his alpha instincts, and his den is no exception. Outside of his rut, he’s fine with the room only smelling faintly of his chocolate fudge scent. Friends are allowed inside even if he’s not in the room (which is almost unheard of for anyone but mates), and he has to really hate someone to so much as growl at them if they walk in.
Kayama Nemuri | Midnight: Nemuri loves her own scent to a ridiculous degree, and she scents her den constantly. Aizawa once almost passed out from the overwhelming scent of the room once, and he’s had nightmares about how it would smell while she’s in rut.
Takami Keigo | Hawks: Hawks cares more about his den than he’d like to. Thanks to his animalistic quirk, his alpha instincts are stronger than the average alpha’s, and while he wishes he could be more relaxed about his den, he can’t help himself from being as overprotective of it as a stereotypical alpha.
Usagiyama Rumi | Miruko: If someone even takes a peek in her den, they’re as good as dead. It is her space and her space only. She’s never let anyone else inside, as she’s been too focused on her career to even think about courting someone. If she ever lets someone in one day, that’ll be akin to a marriage proposal.
Todoroki Natsuo: When they were kids, Touya built his nest in Natsuo’s closet, as the omega didn’t feel safe sleeping alone in his own room. As a result, Natsuo has trouble sleeping if someone isn’t in his den with him, as he feels like he’s failing someone by not having them in the room to protect them. After Touya’s “death,” Fuyumi set up her bed in his den.
