Obanai and Mitsuri's dynamic gets a lot more exploration in fanworks than 'Demon Slayer' ever had time for. The fandom really leans into filling in those gaps—like, how they even started talking beyond that single training scene. A common thread I see is stories that take his harsh exterior and soften it specifically for her, but not instantly. It’s often a slow, awkward process where he tries to be kind, messes it up, and she just finds it endearing instead of off-putting.
Lots of AUs reimagine their meeting, too. Modern coffee shop or college settings are popular because they strip away the demon-slaying urgency. You see Obanai as that quiet, perpetually annoyed barista and Mitsuri as the sunny regular who just decides he’s her new best friend. The core stays the same: her boundless affection persistently chipping away at his walls, but without the life-or-death stakes, his grumpiness becomes more of a socially awkward, protective thing. The development feels quieter, built on small gestures.
I’ve also read some interesting takes that flip the script on his snake, Kaburamaru. In a few fics, the snake actually likes Mitsuri first and becomes a conduit for their communication—Obanai might grumble, but the snake gives him away by being affectionate. It’s a clever way to show his hidden softer side without him having to voice it directly for a long time. The relationship progression often hinges on him learning to accept being cared for, which is a huge hurdle for someone so self-deprecating.

The themes orbiting around Obanai and Mitsuri that really stick out to me orbit a few key emotional poles. First is their canonical 'devotion as destiny' vibe getting expanded into full-blown soulmate AUs, where the mark or the bond is less a cute trick and more a profound, sometimes terrifying, tether. I've also seen a surprising amount of hurt/comfort where one of them—usually Obanai, given his backstory—has to learn to accept care, with Mitsuri patiently dismantling his walls.
Then there's the quieter, post-canon slice-of-life stuff that kills me. Fics where they navigate the mundane realities of a world without constant battle: Obanai struggling to express love in ordinary ways, Mitsuri teaching him about softness. It's less about grand adventure and more about the intimate peace they fought for. The fluff is intense, but the best ones always lace it with that bittersweet awareness of what they survived to get there.

Mitsuri and Tengen’s dynamic in fanfiction clicks for me because they’re both these flamboyant extremes within a world of stoic heroes, yet their extremes pull in opposite directions. He’s performative, loud, all about flash and excess; she’s emotive, warm, and craving a more traditional romantic connection. The conflict writes itself—it’s the tension between his seemingly superficial, hedonistic lifestyle and her deep-seated need for sincere, devoted affection.
I’ve read fics where Tengen’s whole ‘flamboyant’ persona is a shield, and Mitsuri is the one who sees through it because her own kindness is so disarming. That creates this lovely push-and-pull. He might initially treat her like another ‘flashy’ acquisition, while she’s trying to figure out if his compliments are real or just part of the act. The journey from that mismatch to genuine understanding is where the real heart is. It’s not just ‘will they or won’t they,’ it’s ‘can these two very different languages of love ever translate properly?’
Plus, their shared status as Hashira adds another layer—professional respect mixed with personal curiosity. You get training scenes, missions gone wrong, the whole ‘saving each other’s lives’ trope, all while navigating this fundamental misunderstanding about what love even looks like. That’ Edith keeps me coming back.

Okay, so, I've read way too much about these two. It usually starts with Obanai being stupidly repressed. Like, he's obviously head over heels but convinced he's not worthy, which tracks with canon. A lot of authors just speed-run that by having Mitsuri's relentless sunshine wear him down faster than in the manga, maybe through a shared mission or an injury forcing proximity.
What I look for is how they handle the snake and sword stuff. The good fics use Kaburamaru as a character, like the snake nudging Obanai towards her or Mitsuri baby-talking to it. The intimacy of him feeding her with the serpent's help is a huge fanfiction motif—it's a quiet, domestic ritual that gets expanded into entire chapters of soft tension.
I'm less into the ones where they're suddenly super physically affectionate right away. Their canon dynamic is so much about restrained longing, so the development feels more earned when it's slow, with Obanai maybe letting his guard down just enough to accept a hug, and Mitsuri understanding his boundaries without pushing. The best ones make their eventual confession less of a big speech and more of a quiet, mutual understanding, maybe after a tough battle where they realize what they'd lose.

Anyone else notice how the 'found family' thing gets blended with their dynamic a lot? Not just them becoming a couple, but Mitsuri slowly integrating into the Serpent Hashira's weird, isolated world. Fics where she insists on feeding his snake Kaburamaru little treats, or drags him out to festivals he'd normally avoid, feel really true to their characters. It's softer than a lot of KNY pairings because the conflict isn't about power imbalances or rivalry; it's about two people with different flavors of loneliness finding something warm.
There's also this recurring beat where Obanai's jealousy gets reframed. Instead of being toxic, it's shown as anxiety—he's so convinced he's unworthy that any attention she gets from others feels like a threat to the fragile connection. Mitsuri's sunshine personality isn't treated as naive in the good fics, either. She understands his fragility and chooses to be gentle with it, which flips the 'manic pixie dream girl' trope on its head.
And the bandages. So many fics use the bandages as this intimate barrier. The moment he lets her see his face, or she helps him rewrap them after a fight, carries so much weight. It's less about the physical reveal and more about the trust. That specific detail creates a built-in slow burn that a lot of writers handle really well.
My personal favorites are the post-canon fix-its that give them the quiet life they deserved, maybe running a small shop together where Obanai works in the back and Mitsuri charms the customers upfront. Feels like a warm blanket after that brutal ending.
