Everything in brackets is 100% wrong, trust me.

---------------
We're "Mika," guardians that protect the universe meow! The evil beings called "Atasunmo" are out enemy meow... [They were birthed from and receive nourishment from  "Negative strength" and eat all living things], I feel they'll return to nothing, meow... Before long, they'll eat up the whole universe and bring everything to naught, meow... Plus there aren't enough of us opposing them, so we can't attack, meow...
[The one's that oppose the Atasunmo that have talent lend us their strength, they have no choice but to knock down the Atasunmo].  At that time, we took an interest in the humans who live on earth. The humans are holding various potentials! The actions that arose were unexpected even to us... In some cases, their powers exceeded ours... And so I encountered you! If it's you, you'll definitely be able to stop the Atasunmo's conquest of the universe!

BAM

I'm Majiba Kayo. You are?
[I-I said I was "Meow", meow...]
I am!! I'm Meow! I'm sorry!! Nice to meet you!!
	^^see previous chapter

So even though I'll kill the Atasunmo, you didn't choose me.	It was involuntary. 	Done without your permission.
Yep! yep!
I expected that from you Kayo-san! Please do it!
Haa? I dunno anything about this. Don't really care either.
No! please do it! You have to do it or everyone will die! Don't you get it!?

You can kill as much as you want, okay?!
...Sounds good

*skid*
MAJIBAAA
[Yesterday one of our guys got a favor from you yesterday, right? Yeah?!]
TIME TO PAY YOU BACK IN FULL

4
Haa? Not gonna fight?
It seems that even though Kayo-san hasn't transformed, you're still overflowing with magical power. This is the first time I've seen this...
You were like a shield just now, meow.
Meow...? I forgive you for that meow. I have the same magic as you, so I won't die, but that hurt!!
Stop with the meow, or I'll kill you!
Whaaat?

A human. Time to eat.

Kabaaam

6
Wow, that was really impressive! wow...super impressive
I feel really refreshed. This is pretty good...
...
LIGHT IT!
EEEEK!

7
Uh, Kayo-san, don't you want to try and transform?
Haa? What's that? Sounds like a pain in the ass.
You couldn't be more wrong, this is an important factor, you know! Basically, Kayo-san is what we call a Magical Girl, okay? Your transformation is very--
There's no point to this.

[You'll be feel refreshed when you kill people!!]
There's a point to this!

8
Now I'm gonig to imediately check for more Atasunmo!
Where are they where are they~!?
They're here.
You found one? As expected of...

Uh, Kayo-san this is...
The shitty ass highschool. [The guys inside here] lightly brushed against my shoulder and disappeared without apologizing. THAT PISSED ME OFF
Aah, they're bad people huh?

9
CAN'T YOU TONE IT DOWN A BIT!?
Just by walking on the street, [I thought I had my shoulder bumped into hurt]. They didn't apologize, so I was gonna beat 'em until they apologized. THAT'S COMMON SENSE, AIN'T IT?

No~? Ah~ Well~... You know...
You even said before Kayo-san, if you hit people, you'll kill them!
So I'll use you as a glove
Huuh? Thats not part of my job!!

10
GET OUT HERE YOU PIECES OF TRAAAASH	AAAAAA
Ah.
Waaaah!	Kayo-san stop!

11
Why are you already beaten up? Who did this to you?
Majiba?! Why are you here, bitch!?

For some reason a monster appeared and all the guys in the school were eaten!! Only I fought to the end, but [something something] damn this!
I don't get it but your face looks like shit.

12
Oh? There's more? How lucky...
I'll eat you too~
Aaaaah! We're fucked!
