A child was going to have fun with his parents... It should be a day filled with happiness yet... Alas,fate had decided to play the game of endless tragedy on the poor "Crown jewel."

Alphecca was snuggled to his mother's chest. he's still sleepy but he can't help but to admire his mother's eyes, it had two different color. Purple and green.

"Mama's eyes is pretty!" The child exclaim, grinning while looking at his father. "Right papa!" he adds happily.

"Yes, her eyes are the prettiest thing I've ever seen." said his father, kissing the hand he never regret holding.

The child's mother smiles warmly before placing a kiss on both of her boys' cheeks. She love them so much, she will never get tired of their antics. "You two strikes again... This is why you have girls in your palm, Ya..." she trails off... Her eyes going wide from shock as soon as she saw two entities, fighting. The mother hugged her son tight while the father tried to avoid the two beings by stirring the wheel to divert the car's direction away from the entities.

The mother notice that it's...those beings... It's two kids?

One of the being bite his lips, this bitch in front of him suddenly attacks and took his other eye.

"Is that all you got, Thanatos-chan~!?" The pale white girl tilts her head to the side, her long silver hair glows unnaturally under the sunlight. "No wonder, father favors me more!" she squealed, crushing the eyeball in her hand whilst smiling yet it never reach her gold eyes.

Thanatos grits his teeth, "If you hate me that much why don't you just try and kill me like what you did to Hypnos, Keres!" he exclaims.

Keres feign a shocked gasp "I'm hurt by your accusation, Thanatos-chan! I'm not there when Hypnos tripped on the stairs and thus he was doing his true purpose! Haha~" she giggles turning her gaze on the car that was trying to avoid. Oooh~ Humans...!

"Welp, beating a weakling like you makes me hungry."

"Bitch—" The blue haired boy gasp when he felt a kick contacted on his stomach.

"Bastard, you and your twin are the bitches here. You feed on sexual desires. You filthy rat" She hiss, grinding her foot on his stomach.

He smirks at her then say. "You're just jealous, father never feed you. Unlike us, we we're always full with his sexual desires. Every. Single. Night~!" with wink on his working eye.

And there goes his sister's temper. It's more fun if there weren't any humans around... He felt bad for the humans in the car... 'Ah, sorry' he thought 'you'll be pulled in her tantrums.'

Keres beats him into a pulp. Good thing his sturdy. Afterwards, she probably followed the humans. She did say she's hungry.

There are plenty of resources a demon could feed on. They could eat normal human food but it'll never satisfy them... He and his twin feed on desires and souls... Yes, it's mostly sexual desires, lust since humans brims with libido but any desires could work too. As long as it's strong to make them full.

It's easy to make a contract with a demon, they just appear in front of you when you're on the verge of death. Have a strong desire to live, desire for revenge and ect. Just pay for the price though. Souls and other parts of your body that the demon lacks of. If the demon do had a missing parts though.

Demons are loyal to their contractors. they will never betray them... The problem is that if the contractors wished the demons that they wanted them to be forever at their or someone else's side. The demon will be bind to the contract and basically cannot make any contract with anyone.

Thanatos heave a sigh, his sister crush his eyeball so his left eye is beyond repairable, for now... He'll need to find a replacement.

"I'm so done with her shitty treatment." he mutter while going where Keres went... He sense a strong desire there so...

"A mother's desire... Huh." Thanatos wondered what it taste like?

The blue haired boy saw woman sitting besides a dead cherry blossom tree near a turned over car. Her right arm is teared off and she had a child in her left arm, snuggled to her bloodied chest. The child seems to be asleep... Thanatos didn't need to guess where her husband is...

The husband was probably inside Keres' belly, she prefer man meat than a child and a woman's meat anyway.

Thanatos approached the woman so that, maybe he could eat her desire or a contract perhaps.

"H-help..." The woman mumbles, she needs to get her son somewhere safe before that monster comes back... She already lost her beloved husband and if she lost her son... But Sadly she was at her limit at this rate, her son might not be able to leave the area.

She notice a blue haired boy approach them, he's missing an eye and perhaps by instinct...

"B-Boy, you're missing an e-eye, are you okay...?" she asks. The question provoke an amused chuckle from the blue haired boy.

"Ah, I'm fine and shouldn't asked someone if they we're fine when you, yourself is in a grave condition." says the boy, his gaze was on the child in her arm, he's kinda glad that the small child only had a few scratches. "I can help you but only you and if you made a contract with me." Thanatos added, crossing his arms.

The woman frown, she knew this kind of a thing since her family use demons and a legit demon summoner. She looked down to her sleeping son then to the demon. She, herself was at the limit so... There's nothing to lose if this demon child takes care of her son in her stead and she can give him her left eye too.

The demon watches the mother place a kiss on her son's forehead before looking at him, Her gaze feels warm... So this is what it feels to have a mother?

"I...g-guess t-that could work... You...can take m-my left eye too." she said, smiling at the demon.

Thanatos ignored the loud thump in his chest as soon as he saw the smile. He walks to them then caressed her cheek before putting three of his fingers against the woman's eye to carefully remove the left eye. "I, Thanatos Minegishi will create a contract with..." the boy says looking at the woman while gouging her emerald eyeball out.

The woman tries not to make any unnecessary sounds that can wake the child in her arm. Once the is remove the woman utters her name while catching her breath...

"A-Al... Ku..." her name was barely audible, he caught it though.

"And fulfill any wish that you desire but once you die or I've fulfilled our contract, Your soul will be mine... Do you agree?" He asked.

"Y-Yes..."

"Tell me what your heart's desire." The demon states while shoving the eyeballs in his eye socket, blinking and trying to adjust to it.

The woman smiles sadly then gives her child to the blue haired boy. "Protect my child and stay besides him forever... Ana-chan." she said giving the demon a nickname since his real name is a mouthful.

Thanatos sighs, he cannot believe this woman bind him to the contract... "How selfish...of you and you have such a skills at nicknaming, it's incredible."

The woman giggles before slowly and steadily utter something that somehow make the demon's heart ache... The child in his arms stirs from his sleep yet he's not showing any signs of waking.

"Mama needs to go away for a bit... Be a good boy, Alphe..." The mother patted the her son's head for one last time. "I love...you..." and with that said, the woman ceased her breathing and her hand drop on the ground.

A lone tear cascades down from his left eye... Thanatos wipes it, odd... He never cried before so.

A white flame burst out of the woman's dead body... It's warm...

The demon ate the soul then sighs softly. "I'll be full for a few days but it taste unpleasant..." The bluenette looks at the child in his arms who was still fast asleep, the demon heave another sigh... He can't bring him home...

"Curse this contract." He mumbles while walking away, before the child woke up and saw the horrendous sight.

"What a pain..." Thanatos mumbles, leaving the area.
