Motioning for Yoko to sit once again and this time fusing the chair legs to the ground Zero confirmed. "Yes, you're a Lust demon lord. Before you ask me I don't know much about demon lord except that they rival the seraphs of the heavens in books."

"In books? Why don't you know about these things?" asked the confused Yoko

"As I've said before I'm only a year old and I've been your student for almost a year. So in conclusion I spent most of my life in this world going to school." answered Zero

"That reminds me. Why did you attend school as a normal student?" asked Yoko

"For the same reason, you became a teacher and lived in that particular city. I was looking for Dracula's reincarnation." answered Zero

"Yes, but from what I saw you didn't look like you were looking but knew who he was from the beginning. You befriended him on the first day of school and avoided any ties with other people." Yoko remembered Zero only hanging out with Soma and his cousin Mina

"Yes, I knew before I came here who Dracula's reincarnation was and where he would appear." Zero was not hold anything back during this part of the explanation as he found it to be crucial for what was to come next.

"Then who is Mina Hakuba? I assume she's not really you cousin." asked Yoko

"She a normal human who Soma was destined to fall in love with." said Zero

"Destined!? What does that mean?" asked Yoko

"Well everyone has a destiny to be followed unless you can surpass it." said Zero

"What is my destiny then?" asked the curious Yoko

"You are meant to meet a descendant of the Belmont clan and fight together against Soma when he loses to the dark power." Zero was technically not lying since that was one of the multiple endings of the game.

"So Soma will become Dracula after all" Yoko was deeply saddened that one of her students that she had spent so much time with would lose himself.

"Well technically he becomes worse than Dracula" stated Zero

"What do you mean?" asked Yoko

"Vlad Tepes the first Dracula was a man bent on revenge for humans killing his wife Lisa. He was able to rein in the power somewhat and direct it towards humanity. Soma will be unable to do that and will attempt to destroy the world not rule it." stated Zero

"What!" said the shocked Yoko

"The dark power that Dracula was given as a mortal was one that corrupts. He had lived long in isolation for hundreds of years to tame that power. Then he met a woman who filled his heart with love which caused the power to weaken. Soma Cruz is a boy barely 18 years of age he does not have the mental fortitude or years of experience to resist like the original Dracula." stated Zero

"So Soma has to die?" asked the Yoko

"Not exactly if you help me defeat Soma then I'll separate his soul from the dark power. Doing so will make sure that the threat of Dracula ends here." Said Zero

"You can do that?" asked Yoko

"Well I brought you back to life so what's the big deal about ending an age-old evil." said Zero with a slight chuckle

"So to do that you want me to serve you?" asked Yoko

"Yes and in exchange I'll help end the threat of Dracula whilst giving you the opportunity to travel to another world to learn more of magic." said Zero

Yoko looked at Zero wide-eyed as he stated the terms. Zero knew that when Yoko was deeply fascinated with the study of magic as a human and now that she was a demon it became her obsession. Demons were creatures true to their desires and always follow them whatever they were be it lust or killing. Yoko had been turned into a mystical succubus so her obsession would be lust and magic.

"Do we have a deal?" asked Zero as he circulated his mana throughout the dimension causing the white room to change into a dark purple color.

Yoko's eyes unknown to her began to glow with desire when she heard the offer. She wanted to travel and learn all the different types of magic that all the different worlds had. Yoko unable to resist said, "Yes it's a deal."

As she uttered the word all the mana in the room flew into her body and she felt a strange sensation. It was painful but also pleasurable at the same time. As the sensation overtook her she fell to the floor and blacked out.

Zero stared at the unconscious Yoko as he smiled. He had not planned to make such a deal with Yoko in the first place but she herself proposed it and he added on to it. The deal stated that Yoko would serve him but didn't define how or for how long. So he was placing the contract mark on her soul effectively forging a soul link binding her to him for all eternity. His side of the barging only needed for him to take her to another world to learn more about magic after defeating Dracula. This was more specific meaning he could take her to any world and give her a magic book effectively ending his part of the contract. He had gained much from giving almost nothing because he had already planned to defeat Dracula and travel to another world regardless of this deal.

After an hour of mana pouring into her body a crystal-like object with a purple bat etched into it emerged from Yoko's chest and flew to Zero as she awakened.

"What happened? What is that?" asked Yoko

"Our contract has been forged. This is a soul crystal it houses your soul." said Zero

"You took my soul!?" yelled Yoko

"Relax I'm not taking your soul but merely protecting it." Said Zero

"How am I even moving without a soul then?" asked Yoko

"When a soul crystal is created a pseudo soul is created in the body to move it. The pseudo soul moves the body while the real soul is protected in this. Even if you're killed your soul will be safe here. Recreating a body is easy but a soul is difficult so it's better to keep it out of harm's way." said Zero

"So you'll be keeping my soul for me?" asked Yoko with a sneer and sarcastic tone

"If you want it you can have it, but remember that it safest here since only I can freely come and go in this dimension." said Zero as he sent the crystal to her

Yoko was shocked that he would hand it over to her so easily and stared at the crystal floating in her hands. She let it float back to Zero and said sincerely "No you keep it. It'll be safer here."

"Thank you for trusting me. It's not every day a woman hands you her very soul so I'll make sure to take very special care of it." said Zero with a smirk as he kisses the crystal.

This caused Yoko to blush and she turned away to hide her face. She was unused to dealing with men so this was embarrassing for her.
