'Damn it why is the light so bright?' Diablo thought as he raised his hands to shield his eyes from the harsh light. Diablo fully opened his eyes and the first thing he saw is a ceiling of a room. 'Wait shouldn't be i in a coffin?'.

Suddenly he felt something warm touch his cheeks before it moved away. 'So warm' he sat up and looked around, he notice that he is in type of office like room and a red haired woman wearing an odd looking clothes stood in front of him. "Who are you?" Diablo asked the woman in front of him.

"I am rias gremory the one who summoned you" rias said as he stared at diablo while she held a book.

'Summoned me? But i should have been long dead?' Diablo waved his hand in front if him and a large mirror appeared in front of him surprising rias. Diablo's eyes widen when he saw how he looked. 'I'm young again?'

Diablo's appearance was that of a handsome young man with black hair and golden colored eyes. Two horns that bent forwards and slightly upwards. He wore a black fitted muscle shirt that actually show's off his body then over it is a black coat, black pants and black boots. His hands are covered with black fingerless gloves and he wore one black ring. 'So my outfit is still the same'

"Umm excuse me" rias peaked from behind the mirror. "But did i really summon you?"

Diablo look at her and immediately blushed.'does are some large breast' diablo shook the thought out of his head. "It seems so"

"So can i have your name?" She had already given her his name yet he hasn't given his.

"I am the demon king diablo". Diablo introduce with his demon king act.

"Demon king?" Well that was the first time she has heard about that. "I don't know what a demon king is but i know about maou's".

"Ah i remember those, maou's the leaders of devils" he has a nostalgic look on his face. "Any ways does demons still exist?"

"You have been talking about demons but you haven't explained what they are".

"Demons are beings that could be a humanoid animal that is capable of magic, demon lords and kings are human looking demons similar to devils". Diablo explained. "Plus demons eat humans and other humanoid beings".

'So they are different from devils but also similar'. rias shivered at the last part of what he said.

"So my summoner what are you?" He could feel large amount of magical energy coming from her.

"I am a devil". Rias answered him.

At first diablo was silent worrying rias but he suddenly burst out laughing. "Hahahahaha who would have thought that i would be summoned by a devil". He then stopped laughing. "So my summoner what was the kiss on the cheeks for?"

"The book said that i have to kiss the summoned being to finish the contract".

"Book?" Was she talking about the beast summoning book of the devils?.

"Here" rias handed diablo a worn out leather bound book.

Diablo flipped around several pages before he finally closed it. "Can i have this?"

"Yes, i have no use for it anymore since i was able to summon you". Rias believed that he is a strong summon so she doesn't need the book anymore.

Diablo nodded and place the book in his sub-space. 'This book should be hidden for if it falls to the wrong hand then tragedy would happen again'. Diablo then turned his attention back to rias "you said that you have finished the summon ritual but i see no enslavement choker on me".

"What is an enslavement choker?"

"It is the proof that i am your summon, it's like the one on your neck" diablo pointed.

"On my neck?" Rias touched her neck but rather than feeling warm skin she felt cold metal. Diablo made his mirror turn around to face rias, rias saw a metal choker with a broken chain on her neck. "W-w-wha-?"

"I'm sorry my summoner but it seems that my magic reflection ability reflected it back to you". Diablo stood up and apologize.

"Does that mean-".

"It means that our roles have been reversed".

Rias eyes widen in horror. "Can't you removed this?"

"Once again i'm sorry but that is beyond my capability". It's not that he can't do it but he doesn't know how to.

Rias fell to her knees and tears started falling out of her eyes. 'I-I became a slave?'

Diablo saw her crying, he knelt in front of her then he took a hold of her chin and lifted her face so she is looking directly at him. "Seize this needless crying for it will only ruin your beautiful eyes".

Rias did stopped here crying and a feint blush appeared on her cheeks. "B-but my family would surely be mad if they discovers about this".

Despite being a demon king diablo is not evil like the other previous ones. "Then for the time being i shall stay by your side and help you in finding a way to remove it".

"Thank you". Rias gave diablo a hug she then realized that she is hugging a guy that she knows less than a day. "I-I'm sorry".

Diablo parted her head and gave her a smile. "Do not worry being hugged by such a beauty like you is an honor". He tapped the choker on rias neck then it disappeared. "For now i shall hide it but be careful that someone touches it because someone could still feel it".

rias stared at him, maybe this is not such a bad deal. Maybe he could be the one that could help her.

Diablo then remembered something "Tell me something summoner why did you summon me?"

Rias slightly tensed up. "I summoned you because i need someone powerful to help me escape my fate".

He could feel that she hasn't told him everything but for now he would let it slide. 'After all i have a lot of method to make someone talk mwahahahahahaha'.

Rias for some unknown reason shivered. 'I feel something ominous would come to my way'.
