I was in the middle of a war. I think it was between military and terrorist. I didn't know the details of the war. Obviously what i think the bad people are the terrorists.
Maika: We'll have to wipe out those guys.
Shaina: So i can kill those guys?
Maika: I think so.
Shaina: You decided this for yourself. Not that i care because i wouldn't mind if i slaughter those other guys as well.
Maika: I'm only helping them. So you have to kill those bad people.
Shaina: Okay sure. I'll wipe every single one of them.
Maika: Do what you need to do.
Months after the incident with Ishino. I was trained by Shaina. This pitch black eye was the proof of my hard work. She said if i had this eye i could see what she's doing while she controls my body.
Maika: Why wouldn't you just possess me completely? That'll be easier that way right?
Shaina: I could but if i don't train you, you won't be able to use my power to the fullest. Vessels are needed so the devils can use their full power in other places besides hell. By vessels i meant humans.
Maika: I see, so this dark eye was the mark of our deal.
Shaina: To be precise it is.
I can use her power better now. In the end she takes over my body but it depends on my body if i can keep her in good state.
Back on the battlefield. We sneaked in to the terrorist side.
Maika: Devil's blade. switch!
She said i'll just chant that then she'll appear. My weakness is when i'm at my form, as a normal human i'll die then she'll die as well. But if she entered the scene she's immortal.
Shaina: Let's party! Howling blade!
Huge fire was released as she brought out her sword, there were lots of land mines so all of them exploded. She advanced and killed every terrorist i identified.
Shaina: This slaughtering makes me hungry. More! Kill more!
We found the terrorists' hideout.
Maika: Wait! There's children on their side.
"Hey there's a monster who keeps on killing our men leader!"
Shaina: Let's kill each other more!
"The military kept a really dangerous thing!"
Maika: Don't kill the children!
Shaina: I'm having fun! Howling blade, lava spread!
Lots of the terrorists burn as i devour their souls.
Maika: Don't kill the children! Stop it Shaina!
She's out of control, she kept on laughing while killing the people.
It's my fault she burned children as well.
"Please spare my child... he's just a baby."
The leader with his wife and baby.
Maika: Stop Shaina!
Shaina: Shut up. You're bad people. You must be killed.
She licked her sword and has the eyes of a killer with a bloodlust that overflows. I'm scared of myself even more now.
Maika: Don't kill the child! Please!
She slashed the leader in to pieces while it burns as well as the wife and the child.
She left behind nothing but ashes. As the military advances and clears the site.
Maika: Shaina! Let me have my body!
Shaina: Oh, my bad.
I returned in control of my body, and the sword vanishes.
Shaina: So did i do a great job?
Maika: You killed innocent children...
Shaina: You said kill every terrorist...
Maika: I was telling you to stop but you didn't listen no matter how much i said it.
Shaina: I was carried away by my bloodlust. I become like that if i kill too much. Not to mention that was a big hit for just first try. I devoured lots of souls and became stronger.
Maika: But you killed innocent people.
Shaina: Don't sweat it now, what's done is done. You're a killer now Maika.
Maika: Shut up. This deal wasn't the way i wanted it to be.
Shaina: We should really leave this place while we can. If you die in that form i'll die too.
Maika: I'll have to punish you late-
A bullet shot through my arms and almost my heart. And it was followed by missile.
Shaina: Maika!
Maika: Don't kill anyone this time just run! Devil's blade, switch!
As we switched, She burned the place so we can run away and have some cover. I of course regenerated in her form. We ran away and went back to our hideout.
Maika: Switch!
I immediately returned to my body.
Shaina: Now i'm tired. We should call it a day.
Maika: We're not done talking though.
Shaina: If you keep sweating about little things, you won't last long honey. What if that child became a bad guy as well? If more you should thank me by killing a potential bad guy.
Maika: The child is innocent! You should listen. They would what they want to become someday and you just stole his future from him.
Shaina: Does really matter? I told you i'm a devil, you can't order me around.
Maika: Then, if you repeat that same thing i'll forcefully switch and die.
Shaina: What are you saying?! The wrath of lord Satan is scarier than you would imagine.
Maika: Then, you'll listen to me from now on.
Shaina: Fine. I'll consider it.
Maika: You will follow me because it's my body.
Shaina: It's my body now too. But okay if you say so. Right now i'll follow you.
Maika: Good. Now how much soul have we got?
Shaina: We got a lot i could say. All that killing makes me fired up literally and makes me kill anyone who stands in my way.
Maika: Don't kill anyone i didn't judge as a bad person.
Shaina: How can you tell if they are really bad people when you don't even know them? Does it really matter who cares i'll just follow you anyways.
She does have a point. Maybe i killed a really good person there. To their eyes i'm evil, but i believe i just help the right people. I would continue to know them before deciding from now on.
We were killing humans after that. I judged their bad people, they die. Criminals and such. All the bad guys i see they're all bad guys. I killed and devour their souls.
I need to be a useful person who can be strong enough to protect anyone.
One year later. While we were walking, i saw a sales man smiling, it was as if he has plans today. That must be nice. Having a normal life. As we passed through his house we felt something.
Shaina: What is this feeling?
Maika: What's wrong?
Shaina: Must be my imagination. I though i felt a dark power suddenly then it vanished.
Maika: Oh i see let's go shall we?
We walked away noticing it was the start of a new nightmare
