With her eyes it's not really that easy to make out but there's a concentration of cursed energy there that looks like a vine Pokémon of some kind.

Vine Pokémon gets to die! With great prejudice!

Any other takers for immediate death? And is there literally any sign of the boys, she kind of wants to go save them out of sheer principle.

No immediate sign of either more Pokémon or the boys. Some vines do disappear out of her way as the minor curse she exorcised starts dissolving into cursed energy and dissipating.

(She gives the dissipating vines a final kick, just so it knows she hates it.)

Ugh.

Yelling is unlikely to work, her vision here is garbage, and the environment is beholden to the whims of the curse that made it. Trying to find the boys is going to be a massive pain. It'd probably be faster to just find the damn curse responsible and - oh. Actually. She can just zero in on the biggest source of cursed energy and go kill it. It's the most obvious thing in this environment to a sorcerer's senses. This makes it the most obvious meeting point for three stranded sorcerers in a hostile domain. Fushiguro is probably realizing the same thing, or has already realized it. Itadori.... well. She hopes Itadori doesn't die.

Time to go hunting.

It's quiet for a while, and easy to locate the biggest source of cursed energy.

Until, that is, three curses of the vine Pokémon kind emerge from the water quite suddenly where they definitively had not previously been and try to grab her with more vines again.

The big one being asleep was definitely wishful thinking.

She unlocks the sheath to her fan's blade and lets it fly off to be lost in the muck while she dives for the nearest curse. To stab it, obviously. Yes, she could fuss with the vines, maybe play a little game of tag with the curses that can clearly teleport, or, she could start killing them and be done with this bullshit. The others will probably manage to get some kind of hold on her while she kills this one, but that's fine. They are not teenage boys that are both taller and stronger than she is. And if they pick her up, she can stab them too.

They're probably physically stronger than she is, regardless of not being taller or teenaged or boys. The one she's targeted makes a satisfying squelch sound as it dies, but the other two coordinate to try to firmly attach her to a tree by the arms and legs.

Hayashi snaps her legs together, drags her dominant hand with her fan over to her face, and then bites on the vine holding it. With cursed energy, of course. She's not an amateur. And then she can use the opening to slice her legs free so she can have purchase on the ground and drag the curse that's got her other arm over for a complimentary stabbing.

They try to add More Vines to the situation in case it solves anything—

—but that's when a fist bursts through the bark of the tree right next to her arm and grabs some of the vines holding her. "Awesome, that's a hit!" sounds Itadori's voice before his other hand, this one holding the cleaver, punches through the tree too and slices through rather a lot of vines for their trouble.

The way he doesn't seem to even nearly hit her suggests he probably knows what he's doing and isn't going at it blind.

Adding more vines does nothing about the fact that Hayashi Akiho is dragging this damn curse closer so she can kill it. It dies accordingly.

"Oh, hey!" she says brightly. Wait how the hell did he just punch through a tree? No, bad Hayashi, focus.

With the second curse dead, she can actually go back to being a ranged specialist, which she definitely is, she promises. Piercings for this annoying vine curse! Aiming for the center of mass.

It notices what's just happened to its twins and decides to try to flee, but Itadori finishes trampling over the tree (what's on the other side of the tree? how was he there? Euclidean geometry seems to have decided to give up on giving sensible answers to these questions) and quickly leaps over to the other side of the curse, standing between it and the path it was taking to run.

The curse doesn't exactly stop, but it does hesitate for long enough for Hayashi's needles to hit it dead on and pierce it in whatever vital organs it has.

It is incredibly satisfying when curses realize that actually, the smart thing to do is run. Not that it usually helps. Now it has some cursed energy piercings! These do not immediately kill it, but she flares the residual cursed energy smoldering in them, and that manages it. She has a moment to let herself feel a little smug. Ha.

And then it's back to business.

"How did you punch through a tree?" she wonders, as the last curse present begins to dissipate.

"—hm? Oh. Mysterious superstrength of unspecified origin," he says, shrugging. "Always had it."

“That makes no sense, but. Okay. Do you have another inexplicable innate ability that let you come find me? That we can use to find Fushiguro-san, maybe?”

"I was following them," he says, hiking a thumb in the direction of the dissipating curses. "There were, like, six? I killed some, they started running away, then they disappeared but... I don't know, I just knew where to go. It was like following breadcrumbs. Mysterious invisible breadcrumbs you feel rather than see."

“I… see.” She doesn’t, she really, really doesn’t. “So I guess we’re back to my plan of all meeting up at the big curse, since it’s our only real landmark in here. Unless there are any more mysterious invisible breadcrumbs?”

"I don't think so!" he replies, brightly. "I also have no idea where the big curse is, so, lead the way, Senpai!"

“That way,” she says, pointing. “Oh, and. Good job. You’re handling this very well.”

!!!!!! Senpai noticed him!!!!!!!!!

"Thank you," he preens.

Cute? Cute.

Onwards!

They run into a couple more tangela vine curses, who seem to have heard from the grapevine (hah) that these two are trouble and immediately try to flee them on sight. It doesn't work very well for them, between superstrength Naruto-stand-in who can literally leap from a standstill and end up fifty feet away and the plucky heroine who likes stabbing things perhaps a bit too much.

And then they run into a snake curse. With three heads. And it definitely has more than one tail, although where it branches off from its body or how exactly it moves like that is super unclear given how humongously huge it seems to be and how most of its body seems to be hidden underwater at all times.

For this curse, she'd actually like to play keep away. Be a ranged specialist that stays away from the big scary curse snake, and all of its heads, and all of its tails.

"Not the curse this domain belongs to," reports Hayashi, as she begins throwing her sharps. "If you could dismember it or cut off a head or something that would make this go a lot faster. But focus on safety first."

"Got it. Here cursey cursey here!" he singsongs, sprinting over to its heads to serve as bait. Various tails try to stop and grab him, but he almost-effortlessly weaves between them, sometimes even using them as pivots to launch himself closer to his target.

Until, that is, he's hit once by one of the tails and thrown right at one of the surrounding trees with enough force to make it crack and dent. He growls and immediately dodges out of the way of another tail that was trying to impale him against the tree, and near-misses chopping the tip of said tail off with his cleaver.

Which is not to say the snake is leaving Hayashi alone; it's definitely focusing more on the close-up, immediate threat that is Itadori, but it has enough tails to try to swipe and stab at the other sorcerer.

Huh. Having a close combat specialist to distract the curse makes this a whole lot easier, actually. That's nice.

Anyway, yes! Keep away. Dodging, weaving, running and (curse enhanced) leaping and whatnot. The usual. She saves throwing needles for when she's got an opening for one of the many eyes. Turning a thing this large into a pincushion would just annoy it, not do anything that actually matters. This makes it easier to focus on not being grabbed, swiped, or stabbed.
