Making a somewhat more detailed writeup of Kafka, since people may not be familiar with her:
-She has a degree of either bullet control, or bonkers precise aim. At one point, while fighting the protagonists of HSR (and really, really not tryingit's explicitly clarified that she's sandbagging because she wants to lose the fight but has to make it interesting to avoid raising suspicions), she raises her guns up into the air, straight up, and seemingly fires them wildly. This forces a precognitive character to reveal herself and quickly alter the trajectories of the bullets mid flight so they collide into each other harmlessly, as otherwise they would've killed everyone confronting Kafka (she immediately gives up after, as her entire goal was to get said character to show up and take her prisoner for a scheme). I don't know a lot of gunners who can make upwards gunfire into a huge threat.
-Her uzis are not basic uzis. Aside from Path Energy (the thing pumping up the characters of HSR to do special feats, which scales up hard. Like, really hard. Like, the people with the most path energy have cleaved planets in half super casually) making any attacks stronger, they pack enough power to cut through solid ground and steel and leave laser trails behind. This is likely the way her Path Energy manifests in combat, as she can also supercharge simple silken strings to turn them laserlike in turn. In other words, the actual major threat is that she's channeling the energy of the end of all things into her strikes (as that is what the Finality path is about).
-Pathstriders are tough. Like, real tough. The baby-ass Trailblazer (protagonist of HSR) who was legit 'born' (its complicated but tl;dr a body was made for them and they got punted into it when the game starts) maybe a week before what I'm about to discuss, gets impaled by an enormous lance in combat in their first real scuffle after becoming a Pathstrider that is basically the size of their chest, and then proceeds to pull said lance out of their chest, get up and continue fighting against the enemy who sent it. Said enemy then basically pulls a Sephiroth and drops an enormous meteor on top of the Trailblazer and their allies, and just bracing their guard is enough for TB to facetank it. This is not something that happens just in gameplay, mindthe fight is a forcible tutorial where you HAVE to use a damage mitigating skill to survive. Various lore collectibles corroborate that this is just a standard feature of all Pathstriders, as the energy that circulates within their bodies allows them to withstand thing that would kill normal people like extreme temperature variances or dangerous attacks without issue.
-She possesses the ability of Spirit Whisper. This is an effect that allows her to utilize her voice to manipulate others into doing her bidding, a sort of psychic domination. However, this isn't the only effect it has. Spirit Whisper is also an extremely strong mood neutralizer. One of Kafka's allies, Blade, is an immortal (as in he regenerates from any wound he takes) who has been driven hopelessly mad by his regenerative powers. At baseline, he is a senseless berserker. However, Kafka's ability to Spirit Whisper lets her calm him down, allowing him to be functional enough to perform complex tasks, such as driving a car or infiltration, for prolonged periods of time. Range is not a meaningful limitation, and neither does it have to be selective. Case in point from one of her lore tidbits:
"...This woman's name is Kafka, a new Hunter without any information on file, and belongs to no particular organization. She has an ability called Spirit Whisper that allows her to hypnotically manipulate others through language. Recently, she has appeared in Riverland, New Babylon. She was seen communicating with its overchief, Shilde, and absconded with him in witness of 143 people. She then made an appearance at a clothing store and stole a black jacket, two white shirts, and a red dress with 6 witnesses. After that, she was seen by 28 people at an old music record store where she purchased nothing. Before she emerged at the Riverland Guard Station to claim her rewards, she was spotted at the central park with 2695 citizens present. We want Kafka's head, as her lethal crimes cannot go unpunished."
Why does this matter? Because it's likely she can shut down DK's Bananzas by psyching him and Pauline out of a singing mood. If you can't sing well and get in the mood, you can't Bananza. This means Kafka doesn't have to deal with a lot of DK's gimmicks at all.

There's a bunch of other stuff to cover but this is probably enough to start setting the stage. If anybody has any questions I'm all ears. I think this is a weird matchup but also kinda, uh, lopsided against DK, knowing both characters. I'm not sure how he deals with someone who can just shut down his best tricks and actually take his punches while ranging him really hard.
