Where it all began (NPC)

As they walked around in the forest, they couldn't shake off the feeling of being watched. While it wasn't a new thing for Katsura given her upbringing, Nyao on the other hand was on her marks. Sniffing around which caused Katsura to stop walking for a minute.
"What's wrong Nyao?"
"Something or someone is after us, and I don't think they're nice."
"Nyao are you sure?" Katsura said by which Nyao nodded before jumping down. Just to test Nyao's suspicions she carefully walked a little while, pausing at random while listening for any movement. Indeed, Katsura could hear footsteps behind her. This caused Katsura to stare at Nyao before sending her a knowing nod. Katsura and Nyao were so emotional close that just sharing a look was worth an entire conversation.

Katsura didn't want whoever that chased them to realize that they no longer had the advantage of surprise. Katsura "casually" spent most of their time in the forest close to the trees where it would likely be impossible to attack her from behind. Every time they had to turn, Katsura exploited this to subtly look behind her. Just in case, and to indicate Katsura is a significant threat Katsura opened her bag slightly, intentionally exposing her frying pan. Katsura knew from experience in Udagawa Back Streets rules of survival in case of stalking:

Expose your weapons.
Don't display fear.
Don't run unless it's an emergency.
Always be on guard
Listen for every sound.
Don't turn your back unless absolutely necessary.

Nyao also did her part; aside from following Katsura around she listened carefully for every little noise that could help tracking down their stalker. Nyao also kept track of smells around them knowing that the smell of their stalker would persist no matter where they walked.

While they walked around preparing for their unknown stalker, a wind in the trees was happening. The wind itself was not suspicious but that it only applied to the leaves. Their stalker was quick and silent, it was a good thing that Nyao decided to look for a persistent smell which turned out to be moving around the trees. Who was following them around? Katsura of course was used to these kinds of problems but had never experienced them in a forest setting before.

Still the feeling of being watched was exactly the same.

The answer to the question soon showed itself as a shadow hopped in front of them. Aside from not wanting to steer away from her survival rules by showing fear, Katsura had seen such attempts for an ambush so many times that even if she knew the appropriate emotion for this occasion she would be too thick-skinned to batter much of an eye. What really destroyed the entrance was seeing that their stalker was... A worm, not a lion, not a big scary man with a knife. Even Lugh would have made a greater impression. Going with Nyao's word that whoever the worm was, it was not nice so Katsura didn't even bother with her fake smile. The result was from Dokunemon's point of view probably rather anticlimactic as Katsura just stared with her default facial expression.

"Hope you enjoyed the show! Ain't I the best acrobat in this forest? I bet I am!"
"I haven't seen any acrobat in a forest before, so probably." Katsura had her natural monotone dull voice she has when not trying to scam people.

At the same time Nyao was more unexperienced with stalking but it didn't matter that much anyway since her main priority and directive was "keep katsura safe from harm". This manifested as her tracking the smell in an attempt to undermine Dokunemon's stealth and then try to link the smell to the winds. It worked well enough that Nyao was only mildly shocked when Dokunemon arrived.

"Hope you enjoyed the show! Ain't I the best acrobat in this forest? I bet I am!"
"What do you want?"

So it seemed like Katsura was supposed to be happy and entertained? Well Katsura usually didn't know how to feel so might as well make it up. Now Katsura clapped and cheered like it was the greatest performance ever. The strangest part of Katsura  was her ability to change personality at the drop of a hat. Basically Katsura just went all the way to the other extreme like an actor who forgot their line. Of course behind the scenes Katsura has seen such stalking methods so many times before that she had no legitimate way to feel impressed even if she was emotionally stable.

Nyao rolled with Katsura's acting for once, if acting and clapping like a seal could get the threat to go away happy and satisfied then so be it. At least that was how Nyao saw that situation. That being said, if the worm thought either Katsura or Nyao would fall for a distraction while another one got busy that scheme was going to fall hilariously giving that Katsura only acted excited because she assumed it was the appropriate response. In all honesty especially Katsura had her guard as high as before since she hadn't seen anyone stalking her like that who weren't up to something.

Well it seemed like Katsura for once was right in her chosen reaction and luckily it was just that day Nyao joined in on her acting. By all means Katsura was great at manipulating as long as her emotional reactions are appropriate. Katsura was just as much an actor as Dokunemon in pretending to be an excited audience, she had years of experience in making her acts believable if only she could remember her cues. It's a good thing that Katsura understand the tropes of a show well enough to understand that you clap and cheer while the actor bow and then you stop.
Now it seemed like Dokunemon was preparing for the great climax. Katsura reflexly held her Tag tightly while she saw 2 more Dokunemon showed up to give a performance. How Katsura had gained that habit was something she wasn't sure about.

She had obsessive compulsive thoughts about keeping her belongings safe at all cost and Nyao also counted as a possession though Katsura hadn't realized the latter fact about Nyao. While Katsura was too poor to truly become a hoarder she had the mentality of one.

The show itself was great though they could use some practice about coordination.

This time Katsura knew what to do and cheered loudly as response and Nyao joined in. Nyao still hoped that acting like a hyperactive seal would be enough positive feedback to satisfy the trio.

For once it turned out that Katsura's social manipulation worked exactly as it was supposed to. The worms were clearly happy and proud of themselves as they turned to leave. Katsura waved farewell to the trio. Though the idea about dancing worms in a city sounded rather... Weird to her, even weirder things had happen ever since she became a tamer so who knows actually?

Katsura and Nyao was able to relax, for about a few minutes. Before long they could hear a loud desperate scream and whatever made that scream it was obvious that they where getting closer because the scream got louder and louder.

Katsura turned to Nyao who nodded, this seemed like the day for Katsura's stealth skills to shine, before the unknowing being got a chance to see them. Katsura lead them behind the trees and bushes. It appeared that Katsura was just as good at hiding as a Dokunemon. This time Nyao was ready as well, unlike last time Nyao actually knew how to fight back should the threat be real for once.

The only thing left was waiting and trying to find out where and why someone was screaming and whether they too should be afraid.

So the danger had worn off it seems, the screams had ended and the forest turned quiet. Now the only problem is a forest is not supposed to be "that" quiet. Perhaps most strange was how the abrupt the end of the scream felt almost like if someone had turned them off.

But before Katsura or Nyao could muster a comment to the turns of events a voice out of random shouted from the side. Reflexly Nyao was about to attack when she noticed the holy ring on its knee and ceased the attack. Likewise, Katsura was covering behind Nyao until she reached the exact same observation.

"Don't sneak up on people like that! Didn't you just hear the screams?"

Now that the initial shock was under control, Katsura and Nyao had time and resources to comprehend the Tapirmon's words.

"Why are you here, by the way? The forest's acting all weird, yet you still insist on walking through here. Humans are so weird."
Nyao thought about how hypocritical it sounded to call Katsura weird in a situation like this but decided not to call the Tapirmon out on this. Meanwhile Katsura was the one answering.

"This is where I arrived when I first visited the digital world and it was nice 10 minutes ago."
"Eh, anyhow. I guess that this place being like this makes it a bit more entertaining? I'm not sure if it's that way for humans, but at least it gives me some stories to tell when I hang out with the guys and we tell scary stories around a fire. Do you do the same?"
Now calm-ish Katsura could resume her cheerful fake personality with the accompanying smile.
"I don't really 'hang out' with guys aside from Nyao and whoever I'm meeting on my way. Why do you ask?"
