Rize

"A-All the magic I know?" She muttered with confusion. Why would someone who seemed so proficient in magic ask her about it?

She didn't dwell on it and sincerely told him everything she knew, "Magic was the power born by researching about the Devil's Demonic Power which also became a power that humans can control.

There existed multiple types of magic such as Norse magic, Fairy magic, and various different types of magic with different equations including the magic that Gods use.

It is said that the majority of magic that is used by the ordinary Magicians are those created by the great Magician; Merlin Ambrosius which involved reading the flow."

After saying this she took a pause and looked at Ryujin. Sadly she couldn't see what was behind the mask, all she knew was that he was a kid from his build.

Ryujin looked at her in a baffling way, "Are you a bookworm? What's with this bookish answer, Why not become a teacher? You can bore your students to death and eat them without any effort at all."

She felt her blood rush to her face as she blushed in embarrassment. To think she was being humiliated even after being so subservient.

But she knew she had to endure. She would do anything to survive, how could a little embarrassment cause her to lose her cool in such a situation.

Calming herself down she looked at him with teary eyes in a pitiful way.

Ryujin ignored the look she was giving him and said in a flat tone, "Continue."

She could only continue her 'boring' lesson, "The magic system used by humans is categorized into two major types.

Western magic and Eastern magic, the former being a system of spells and magical knowledge founded in Europe while the latter is a system of sorcery that originates in Asia; magic used by humans originates from the knowledge of Devil's demonic power and the miracles of Gods of different religions.

That's all I know about human magic besides I don't even use magic myself since I'm a devil..."

After that, she told him all the basic incantations she knew.

It included Darkness, Fire, Water, and Wind. She didn't know about the rest.

After finishing everything she nervously looked at Ryujin.

Ryujin didn't pay much attention to her but after a second of thought he decided to analyze the information later, his strength was about to disappear after all.

He took something out of his small bag and put it in front of Devil.

Seeing the thing he pulled out, her eyes were immediately filled with horror.

"B-But I answered all your questions honestly! Why!?"

"Why? I wonder myself but I'm the one in control here, either you obey or die."

As soon she heard that the light in her eyes dimmed, She gradually lost hope for survival and a few drops of tears slid down her face.

Looking at her Ryujin forcefully grabbed her face. He pried open her mouth with his fingers and chugged the tube filled with 'Holy Water' down her throat.

Lifelessly observing the scene, she waited for the pain to come but even after a few seconds nothing happened.

Confusion filled her eyes.

"W-What did you just force m-me to drink?" She said softly, as if afraid that the pain would suddenly come at any moment.

"It was Holy Water contained in 'Virioxium Berefiatate'. It's a solid sticky liquid that can contain any liquid in it. Special isn't it? But it disappears too quickly unless contained in an airtight container. Its sticky nature then infects the liquid it contains.

So basically if the Holy Water inside you is let lose it stick to your insides, causing you eternal pain."

A chill went down her spine and her entire body trembled in disbelief but before she could even gather she thought he took another tube and once again forcefully made her drink it.

After that, he took out a blue pill and threw it down her throat.

"Just a safety measure and yeah the blue pill will allow you to not suffer 'Eternal Pain' for now. You'll have to periodically take these pills to avoid it from dissolving. Also don't have any funny thoughts only I can make them. Besides you're a stray devil, no one gives a shit about you."

Saying this, he got off her stomach and leisurely sat near the tree behind him while leaning on it.

Of course, he was bullshitting. There was no such thing as Virioxium Berefiatate.

After he got up from her she slowly stood up.

Her legs were trembling and it didn't seem like they would allow her to stand as she fell on her knees the moment she stood up.

Her pretty face that was covered in wounds had tears streaming down it.

"What is it that you want from me?" Her voice was lifeless as if she had lost all will to live.

"What do you expect? From now on you are to follow all my orders. In simple words, you're now my slave and I'm your master."

'I had done so much just to escape from one hell to land in another!?' She was resentful, angry, upset, and full of grief but what could she do? she was powerless.

When she had previously told him that she would do anything, it was a bluff. She was prepared to scheme against him to gain her freedom again but he had practically cut off all her escape routes.

He was right, She was just a stray devil nobody cared about her.

Looking at her lifeless face he crossed his arms in thought, 'What was more beneficial? A dead devil or an alive one that would listen to all his orders?'

She would also serve as a good way to find other devils than roam around aimlessly at night. He could also learn more about devils from her.

She could also be his sparring partner and most importantly she was free eye candy. Why? Because she looked exactly like Rize from Tokyo Ghoul.

And Rize was one hot bitch.

When he first saw her he had thought he was in some kind of Mixed world of Tokyo Ghoul and DxD but he later found out that she was just a stray devil.

But of course, he wouldn't hesitate to kill her the moment he found her death more beneficial to him.

What mattered the most was that she would become his lab rat. Devils were fascinating creatures, They had such long lives, superhuman qualities, etc.

He wondered if he could somehow get them without actually turning into a devil.

He didn't mind experimenting on a devil that feasted on humans.

Maybe he could mix Angel and Devil blood to become a hybrid or something? Or maybe mix fallen angel blood as well?

If that experiment worked then maybe a dragon or something? Though he preferred remaining human but if he couldn't achieve his goals as a human then he wouldn't hesitate to abandon his humanity.

He also wanted to create a faction of his own, independent of race, just his own personal army ready to receive all his orders.

Thinking of this he let out a self-deprecating chuckle.

These were all plans for the future.

He now had to deal with the devil he didn't kill.

"Now tell me your name and background."

Hearing his voice she looked up and replied in a dead tone, "My name? My name is Rize... and I'm a reincarnated devil..."
