It’s a shame that I didn’t have time to post earlier, but the newest chapter (139) confirms it completely:
Ayshe’s narrative parallels Krone’s from the escape arc
I have been thinking that with all the parallels from the escape arc, we have been missing Krone’s tag game and her becoming an unexpected ally to the kids.
But looking at Ayshe now, we can see a very similar narrative:
Both of them are introduced as very dangerous, and are seemingly assigned to just keep watch over the kids and the kids:
Both also have exceptional abilities: Krone is extremly strong and fast, whereas Ayshe has exceptional senses and shooting skills. In both cases they show their skills in a tag game, in a forest, looking for Mujika and Sonju isn’t that different from tag.
There are a couple more panels that are drawn as parallels:
Also, Don and Gilda are easily outdone by both of them:
It doesn’t take much from either Krone or Ayshe to discover Don and Gilda’s intention, and in both cases, they unexpectedly offer to join forces, rather than tattle to their superiors (Isabella in Krone’s case, and Norman in Ayshe’s).
We learn about both that they have their own motives that neither the kids or us as readers expected as to why they don’t want to follow their superiors agenda.
However we also learn that neither Isabella nor Norman trusted them. In both cases they are assigned as guards as merely distractions, and the real “traitor” and information suppliers are Ray (escape arc) and Hayato (new arc), who again no one saw coming.
Edit: Given these parallels, I don’t expect that Ayshe will be successful in her revenge against Norman. After all, Krone was easily outsmarted by Isabella, but until we see Ayshe with a butterfly, I am hoping that she won’t have to die as Krone did after her failure.
I think that the poster of the leaks may have forgotten what Yuugo has taught the kids: that’s it’s actually worse to kill a wild demon than to escape it.
They even get more pissed off, and it’s not like it’s that easy to kill them to begin with. If you don’t need to kill it, you are just wasting valuable resources like bullets or arrows.
So Don is probably being more practical than just merciful, but we know Hayato is inexperienced, and wouldn’t understand this yet.
Also, I wonder what kind of plant demon attacks Hayato, if it’s branches like the roots in the caves before they met Mujika, or a bit more like this, lol:
Also, we are yet to have a parallel to Krone’s tag game. I am thinking Ayshe with her superhuman senses may be the stand in for Krone’s superhuman strength and speed.
After all Krone also easily defeated Don and Gilda, so it makes sense then for Ayshe to see through them trying to mislead her:
I wonder if Ayshe speaking at the end is a bit like this:
At least Don and Gilda tried, but like we knew from the start Ayshe had exceptional abilities. Also, I wonder if she hid understanding human language on purpose, or if she is just very antisocial?
She knew just how long to wait in hiding before hunting, she didn’t mind watching 25 kids for hours at a time, even when they insisted on braiding her hair (“Anna taught me! Isn’t it pretty Ayshe?” sure.), she lived in the same house as the man who killed her father for years now and still hadn’t lifted a finger to hurt him (setting her dogs to take his dinner didn’t count, and besides, it made Gilda laugh), but really this was too much.
“What.”
“Isn’t Mars sweet, Ayshe?” cooed Sherry, gesturing to the hairy beast in Gilda’s arms.
“Younamed that thing?”
“You name your dogs,” pointed out Don.
She shook her head. Her dogs were useful:they could hunt, scare Norman, keep guard, scare Norman, drag heavyweight, kill (not Norman, not yet). But a cat?
“He won’t get in your way, I promise,” said Gilda, smiling sweetly, and Ayshe couldn’t say much else to that.
***
Gilda stayed true to her word. Every morning, without fail, she brushed that thing’s matted hair, gave it a bow for some reason, fed it something out of a can instead of letting it hunt, cut its nails, and of course, kept it out of Ayshe’s way.
At the end of every week, when the children went on one of their long trips and returned, predictably, empty-handed, Ayshe watched with bemusement as Gilda held that thing close to her for hours at a time.
“Mars doesn’t have to be useful, you know,” said Ray, who had been watching her eyebrows raise higher and higher after one of those trips.
“It doesn’t do anything.”
“It doesn’t have to. Gilda likes it because it shuts up and follows her around when she’s upset.”
“She has 43 siblings.”
“Yeah, but those don’t ever shut up,” said Ray fondly.
“I have 3 dogs. She didn’t needto get a cat to keep her company.”
“Sounds like you’re jealous.”
Sounds like you need to keep your mouth shut.
Lifting herself off the dogs curled around her, Ayshe manoeuvred herself around the crowded household into Gilda’s room.
As always, she was hunched at a corner of her bed, her arms wrapped around the thing - Mars.
“Oh-hello Ayshe!” she said, startled but not unwelcome.
“Hello.”
Gilda likes it because it shuts up when she’s upset.
Tucking her knees underneath her, Ayshe stared silently at Gilda. 
“Did you…want something from me?”
She shook her head. It works for the beast but not her?
And suddenly, Gilda burst into tears. What the hell, Mars?
“I’m sorry - it’s just Anna wants to go to medical school and money’s still thin and I knowNorman and Ray are working but I want to help out but the only thing I can do is help with searching but we haven’t found a single lead and Alicia, Phil and Yvette are upset and Don’supsetso I can’t be upset in front of them, and it’s Violet’s birthday next week and I haven’t planned anything and Eugene’s allergic to mangoes now,” she sobbed.
“…Staying away from mango peel helps with allergies,” was about the most useful thing Ayshe could come up with.
Gilda stared at her. And without warning, laughed. Had she said something funny?
“You’re right, Ayshe. There’s so much less to worry about in this world and I’m worried about…allergies?” she chuckled, wiping at her eyes.
Ayshe didn’t think she had said anything even remotely related to worrying.
“Would you like to hold Mars?”
No.
“Okay,” said Ayshe, holding out her arms.
It - Mars - began to purr, nuzzling it’s fat, orange head against her shoulder.
“I can…fish for Mars. You’d save money on his food that way,” she offered.
Gilda blinked at her, surprise evident on her face.
“And my dogs don’t forget a single scent. They might help with your search. I don’t know anything about birthdays but - “
Gilda cut her off, wrapping her arms around her shoulders.
“Thank you,” she said, lacing her fingers through Ayshe’s hand.
Ayshe wondered if her chest had stopped working, whether it was normal for her heart to squeeze in on itself this way. She didn’t trust herself to speak, her ears flushing red for some strange reason.
A loud hiss from Mars, from being pressed in on from both sides, broke them apart (what the hell, Mars?) the cat darting out of Ayshe’s arms, out into the hallway.
“Mars!” yelled Gilda, chasing after him, Ayshe on her heels.
They had lost track of him, amidst the clutter of the children-filled household.
A loud meow, a series of loud sneezes, and an even louder laugh from Ray pulled them both into the kitchen.
“Oh hello, Gilda! Ayshe - ” began Norman warily. And then, sneezed.
“Sorry - ach-choo! - I think I’m - ACH-CHOO!” Curled around Norman’s legs, quite unbothered by the sneezing was a very relaxed Mars.
“You’re - ” gasped Ray, clutching at his sides, “you’re allergic to cats?!”his words punctuated with laughter.
Norman didn’t seem to find the situation quite as entertaining. Sniffling, he beckoned for Gilda to take the cat away.
Chuckling herself, Gilda scooped Mars up into her arms again.
“Sorry, Norman! It won’t happen again!” It absolutely will.
Together, Gilda and Ayshe walked out of the kitchen, Ray still laughing, Norman still sneezing.
Ayshe smirked, running her hand along Mars’ back.
Maybe having a cat around wasn’t such a bad idea after all…
