["Pardon the intrusion."]
CRASH.
After announcing my arrival, I break the window of a house next to the school's back wall.
Manners, first and foremost. I'm a well-mannered rat kid.
["Is anyone here? Some asshole broke your window."]
Since no one answers, I go up to the third floor of the house.
There are many ways to get to my school; I chose the one that left me at the back of it. Why? Who's going to enter a school full of giant wolves? Me?
You wish.
According to Rat Kid 5's information, the wolves' most active period is the morning and a large part of the afternoon.
That's why I'm not surprised that I almost completely stopped running into monsters as I got closer to the school.
But that only proves how dangerous those bastards are. I saw several wrecked houses on the way here.
Why don't they attack the students?
According to Rat Kid 5, the stairs are completely blocked with desks.
It's to the point that it would take them hours to get out themselves.
["So, let's see who I recognize."]
After climbing onto the roof of the house—which would be like the third floor—I use the binoculars I brought to look towards the classrooms.
["Ohhh, it's just like Rat Kid 5 said. A large number of students on the 3rd floor and a large number of wolves in the courtyard."]
Oh, and I also found my neighbor. It's a good thing she hasn't died, or my aunt wouldn't stop complaining no matter how much time passed.
I told Rat Kid 5 to stay in the middle classroom, but in retrospect, it was a bad idea not to ask what she looked like.
Can't blame me; it's a rat kid habit not to ask those things.
["So, pardon the intrusion."]
flashhhhhhhh
Manners, first and foremost. I announce my arrival and fire the harpoon.
The harpoon shatters the classroom window and sticks into the wall. Of course, it has a rope tied to it, and I also tied a bag with a walkie-talkie to it.
After all, communication is down.
At the sudden event, the students started screaming in terror, not understanding what was happening.
Tsk, what loud-mouthed crybabies…
["Rat Kid 1 to Rat Kid 5, respond, Rat Kid 5."]
I call on the walkie-talkie. I need to coordinate the situation with Rat Kid 5 while we wait for the dogs to go to sleep.
I watch the classroom with the binoculars, but I only see a bunch of brats staring at the harpoon in terror.
["Asshole, answer this piece of crap once and for all."]
As I complain, a single girl approaches the harpoon. The rest look alternately between the girl and me.
Realizing the harpoon had a rope, they started looking in my direction and found me.
The girl opens the bag and tries to grab the walkie-talkie.
What the fuck is wrong with this vixen?
["Hey, gal vixen, who the fuck told you you could grab the walkie-talkie?"]
Looking at the girl up close, she reeks of being a "gal" or a popular girl, whatever you want to call it.
What the fuck is Rat Kid 5 doing letting this vixen touch my things?
["Th… This is Rat Kid 5… Over…"]
The girl shrinks as she answers, her voice is also subdued. Is she ashamed?
["….. AHHHHH, don't fuck with me, vixen. Who do you think you're fooling?"]
["I-I'm not lying, okay? You damn Rat Kid Leader."]
["So you really are Rat Kid 5? You're a damn girl?"]
["S… so what if I am? Got a problem?"]
["Hell yeah, I do! You're the only rat kid in the group who's the playboy type. I was hoping you'd take me to pick up girls when this is over, and now it turns out you're a damn girl?"]
["Tsk… What's with that ridiculous reason for helping someone? More importantly, where's my damn limited-edition chocolate?"]
["Bitch, I smeared it on my staff; feel free to come and devour it whenever you want. Since you're a gal, I'm sure you're used to it anyway."]
["HA, I don't want to hear the jealousy of a virgin bastard. And I'm not asking about the ¼ of the bar you had to use to completely cover such a tiny member. I'm asking about the remaining ¾, you moron."]
["I smeared that part on my ass cheeks. Enjoy."]
["You're looking for a fight."]
["Kakakaka, come get some if you've got the balls."]
["I'm a damn lady."]
["If you're a lady, then I'm the Count of Monte Cristo."]
["You little… HUH?"]
As we were in the middle of our greeting, a boy and a girl with neat, serious appearances approach the vixen.
It seems they started an argument or something.
Vixen, you dare leave me hanging?
As I was thinking about how to insult her, the students who were in other classrooms and hallways started to crowd into the vixen's classroom.
It's easy to see that the groups are divided by their personalities: jocks, popular kids, nerds, delinquents.
Now they all seem to be discussing something with the vixen at the center of it all.
Since their disgusted faces are such a delight, let's give them some time.
["Kekeke, suffer, vixen."]
Where'd I put the snacks?
📖 Monster Journal — Entry No. 87
Name: Bulla Caótica
Alias: "Pipe Squealer," "The Invisible Karaoke," "The Echo Nobody Asked For."
Danger Level: 3/10 → Annoying as having a neighbor with a power drill on a Sunday at 7 a.m.
Aggressiveness Level: 2/10 → Doesn't seek to kill you, just to perforate your eardrums and your patience.
Type: Sonic / Territorial
Elemental Affinity: Acoustic Vibration
Primary Habitat: Enclosed, damp spaces (bathrooms, basements, tunnels, rooms with bad acoustics).
General Description
A minor creature, invisible or barely perceptible as a distortion in the air. It manifests through high-pitched shrieks, metallic bangs, and annoying resonances in walls or pipes. Occasionally repeats human phrases, but in ridiculously high-pitched or distorted tones, as if played through a cheap speaker.
Behavior
The Bulla Caótica does not seek to cause physical harm; it feeds on the discomfort and mental disarray generated by constant noise. It tends to settle in places where it can amplify its effect: pipes, ducts, basements with echoes. It frequently interferes during moments of silence or concentration, causing migraines, irritation, and even fits of rage.
Known Abilities
Emission of shrieks and metallic bangs that can last for hours.
Ability to mimic human voices in a distorted manner.
Can modulate the acoustics of the environment to amplify its effect.
Known Weaknesses
Loud music drives it away, especially repetitive rhythms like reggaeton or cheap techno.
Prolonged and total silence seems to disorient it.
Assumptions and Contradictions
Some believe it feeds on psychic energy linked to human stress.
Others relate it to "acoustic parasites" from old urban legends.
Theories exist that associate it with entities from sonic planes, similar to "cursed songs" from the internet.
Origin and Comparatives
Compared to minor poltergeists or noisy house spirits. Associated with phenomena of haunted pipes, houses with strange acoustics, and the legend of "echoes that answer on their own."
Sighting Report
In 1999, a karaoke bar in Korea closed after weeks of complaints: every time someone sang, the Bulla Caótica would shriek louder to compete with the customers. Witnesses claim the pipes would "sing" in the early morning even when the establishment was empty.
Rat Kid's Note (Astrad)
"Deadly threat? No. Unbearable nuisance? Absolutely. It's like having a drunk neighbor with a cheap karaoke machine, but living inside your walls. Pro tip: record its tantrums, upload them as a remix to YouTube, and turn it into your viral revenge. At least make your eardrums worth some money."

RatKid8: Yeah, yeah, that's the one! The bastard attacked me when I was taking a shower.
RatKid6: And what happened?

RatKid3: LOLOLOLOLOL.
RatKid2: So the critter basically performed a "duet" with you.
RatKid1: Just like the journal says, low hostility. Annoying but not lethal.

RatKid10: Hey RatKid1, your journal is right this time.
RatKid1: Obviously, my tomes are more reliable than Wikipedia.
RatKid7: Confirmed: the critter sings better than Rat Kid 8.
RatKid8: Fuck off.
