'My head is all fuzzy... What happened...?' Rem paused for a few minutes to get herself together.
After a moment, she understood what happened.
'That was stupid of me, wasn't it...? If I didn't ask for the system to take over my body, I wouldn't be in this mess. I would probably be dead by now too. At least I'm not dead.' Rem sighed in relief.
This was when she realized where she was.
'Isn't this the same door from before?' Rem stared at the chained door.
The door was just a normal door, except it was large. Larger than your normal double door. You might as well call it a gate.
'I ended up here thanks to me allowing the system to take over my body. How can I get my body back?' Rem wondered.
She pondered about how to get out of this place. Many minutes passed, but Rem still couldn't think of a solution.
'Maybe looking around this place would allow me to get some clues. I'm clueless anyway.' Rem walked towards the large, chained door since it was the only thing that was here, excluding Rem herself.
Rem didn't want to go anywhere far from the door. After all, she didn't want to get lost. Everywhere else was what seemed to look like endless darkness.
'If this door opens, what would happen...?' Rem questioned, moving her right hand towards the door to touch it.
However, her hand was immediately pushed back by some kind of energy.
'As expected. This door has something protecting it. With my strength, I can't open that door forcibly.' Rem gave up on trying to open the door for now.
In her head, multiple questions didn't go away even after Rem tried pushing those questions out of her head.
'Curiosity killed the cat, they said.' Rem sat down and continued to think of solutions and answers.
...
"Rem? Is that you?" A familiar voice asked.
Footsteps could be heard walking towards Rem. The Rem right now is being controlled by the system. When Rem turned around, she met with Kaito. She didn't say anything in response. Instead, she walked away, walking towards a large group of people. However, Kaito steps in front of Rem, just like Samael did.
"Why are you here?" Kaito confronts Rem, demanding answers.
'Annoying rat... Should I kill him now...? No, that would be a careless thing to do.' Rem looked at Kaito straight in the eyes.
"Why aren't you saying anything? Are you okay?" Kaito kept on asking questions.
"Why can't I be here?" Rem questioned.
"Demons are here! You can easily get yourself killed...!" Kaito whisper yelled.
"Why do you care? You handed me over to those people from Orthio City. Did you forget already?" Rem raised one of her brows.
"O-Oh, uh... About that, please let me explain. I-I had to do that because—"
"I don't want to hear any of your excuses. You broke my trust. You don't have the right to interfere with my business." Rem said coldly, cutting Kaito off.
"You changed so much, Rem," Kaito mumbled under his breathe.
"People can change over time, depending on what they're going through." Rem responded as she walked towards where she was going.
Kaito just stood there, dumbfounded.
(A/N: Please keep in mind that the system is controlling Rem's body right now.)
...
All of a sudden, chains began to appear from where Rem was standing. Rem moved away from the chains, but the chains were aimed at her at an extremely quick speed, a speed even Rem couldn't keep up with. The chains were so fast that Rem would've thought they teleported.
In less than a minute, Rem was completely chained up by the chains. The chains were the same ones as the chains on the door. The chains were dark gray and they emitted a black and red aura. The aura was very strong. It was strong enough for an ordinary human to see the smokes of black and red smokes coming from the chains.
'What's going on??!' Rem struggled to get the chains off of her.
No matter how hard or how long she tried to get the chains off her, the chains didn't budge.
Every passing minute, the chains seem to become stronger. Soon, Rem gave up on trying to get the chains off her using her strength. She would rather preserve her energy than waste her time on something she knew, wouldn't succeed.
'How do I get out of this mess???' Rem thought, beginning to have trouble breathing.
It felt suffocating under those chains. Not long later, the real Rem passed out in the darkness with only the chained door, and her chained self in it.
...
'More, more, more, more, more!' The system controlling Rem yelled inside.
The system used Rem's body to shift into her monster form. Then, Rem killed every living being in sight. From demons to humans, humans to animals. Rem left no one who was near her, alive.
'I need more blood, more!!!' Rem decapitated a man's head by making a slashing motion with her paws.
Every one of her attacks caused at least one living being to die.
As more blood was shed, something inside Rem began to grow.
"GRWARRRRRRR!!!" Rem growled loudly.
Her roar could be heard everywhere in Arka City. She roared because she knew stronger living beings would try to stop her when they find her. Roaring would give her location away. Another reason Rem roared was because her roar allowed everyone who was weaker than her or has no resistance to become paralyzed. That way, she wouldn't have to chase after weak living beings and waste her precious time.
'This isn't enough. I need more blood...!' Rem jumped on the roof of a house, causing a huge dent on the roof.
She was planning to destroy all of Arka City in one go even if it has to cost all of her mana.
Before she could go any further, she was stopped by someone. That certain someone is Kaito. Only this time, this Kaito is different from the Kaito from earlier.
