"what do you want?" Yami asked as she looked at the woman in front of her.

"I... I want to live forever. oh lord of hell, help me regain youth." The old man said as she bowed before her.

'system, can I even do that?' Yami asked with a slight frown.

*you can, just have her drink your blood.* the system said calmly.

"what do you have to offer," Yami asked as she crossed her hands.

"anything, I will follow you for the rest of my life." the woman said

"I can give you what you wish, but I want everything you have. it shall belong to me." Yami said as an evil smile formed on her face.

"... I agree." the woman said as she hesitated for a moment. As soon as she agreed, flames appeared in front of Yami. The flame turned into paper.

*sign your name, don't use your full name. Just a part of it. you don't wish for people to know your name host." the system said

Yami already knew this from the memories she has gotten. The name of a demon is connected to its soul. If one knows their full name, they can locate the demon access each world. one could even curse them from afar.

yami calmly signed using Yami on the paper, and after she did, she left that the world that was trying to kick her away disappeared.

"Now, open your mouth," Yami said as she cut her finger using her sword. The woman hesitated before swallowing the blood.

As room as she did, she rolled on the ground in pain as she held her neck. Red lines appeared on her body as the life began to disappear.

Slowly the woman got young as her skin got paler.

*she turned into a vampire and succubus.* the system said calmly

Yami nodded as she looked at this woman, looking at herself in excitement.

"bow," Yami said calmly. The woman suddenly fell to her knees without able to control her body.

"What is this." the woman asked in horror as she looked at Yami.

"everything, including your free will, belongs to me," Yami said as she held her face with a smile.

"you demon." the woman said, seeing that she was tricked.

"you are right. I am a demon. You are to be my slave from now on. you got nice looks." Yami said as she couldn't help but lick her lips.

"what are you planning on doing?" The woman asked in horror.

"I first need a shower. How about you join me? You can be my first." Yami said softly...

Yami calmly got dressed as the woman that summoned her laid on the ground, asleep.

'I need to turn back into a boy, and fast. Although it was nice having someone...' she thought as she walked outside.

*host is weak to sunlight. You should be careful." the system said calmly.

"I forgot I was a vampire. I will just wait until it's dark." Yami said as she returned to wake up the woman.

"Anna, was it? Wake up," yami said calmly as she sat down.

"yes, master," Anna said as she sat on the ground.

"tell me of important things I should know." yami said calmly.

"this world is currently at war with the demon. The seal that sealed away the demons has gotten weak. But a hero was able to pull the sword that was given to us by the angels. the hero is now facing the demons and try to kill the demon lord." Anna said

"How strong is this demon lord?" Yami asked

*host he is a low-level demon of the peak stage.* the system said

"I don't know," Anna said

Yami fell into deep thought before asking the system.

'if I were to face it, how long would I last?' Yami asked

* I don't know. All I can do is sense it. But if it's a normal demon host might win, but if it's even slight special host will die. The host should sit back and eat souls. host just need to eat 40 souls before breaking though.* the system said

"starting tonight, you will leave to search for humans. Don't suck their blood or anything. just knock them out, and we can enjoy the meal together." Yami said as she smiled.
