"Miss Pheles?" Ryuji Suguro X OC Blue Exorcist

Surprise adoption!

"Shiro..."

The short, pale girl laid there, on a large purple pillow surrounded with flowers. She had a swaddled child in each arm, while one sat on her chest.

"I can't believe what I'm seeing..." said the silver haired man, wrapped in a grey jacket and blue scarf. He was holding a sword with a blue sheath.

"Aren't they adorable?" she asked, looking from him to her newborn children. "My little baby's... I call the boy with the blue flames Rin, and the pale one Yukio! And the little girl, her name is Miuna..." She paused slightly, struggling to keep her eyes open. "Be strong, and live. Prove to everyone that demons, and humans, can live in peace..."

She stopped speaking, allowing her face and body to relax while closing her sapphire blue eyes.

The Silver-haired man crouched down, eyes slightly wide. "No, stay with us! Yuri! YURI!" His voice was urgent, obviously trying to wake her up.

"Well?" The purple-haired man spoke from his place, standing politely with his hands behind his back. "The Vatican ordered you to kill her and her child, excuse me, children. She's dead, but that still leaves the little ones. What are you going to do?" His playful tone almost sounded like he was teasing the poor man.

"They've inherited Satan's power and as long as they live there gonna suffer for it..." As he spoke, he stared unsheathing the demon-killing Kurikara sword.

The young blue flamed male baby made a small noise, causing Shiro to pause. He stared, being lost in his thoughts.

"What's the matter?" Antagonized the voice from being him. "Aren't you gonna exterminate them?

Mephesto spoke with a smirk, clearly wanting to see how this would play out.

"The boy with the flames smiled at me..." Shiro spoke in a whisper like tone. "I'm trying to kill him and he's smiling at me..."

Shiro sheathed the sword. "Mephisto."

"Hmm?" Questioned the purple-haired male.

"I'm gonna raise these two." He said, not looking away from them.

"What?" Asked Mephisto, obviously surprised.

"I'll raise them to be a couple of fine human children."

Mephisto suddenly busted out laughing. "Wait you? Your gonna raise the spawn of Satan? You, the cold-hearted exorcist?"

Mephisto continued laughing, not seemingly stopping anytime soon. "Hahahahah! Talk about imposable!"

"Yeah well, there's only one way to find out!" Claimed Shiro, almost yelling.

Mephisto stopped laughing, before asking a question. "What about the other one? Are you planning on just taking two of them?"

"I can't really take the girl..." He said, obviously slightly upset. "She'll be raised with almost no contact with other girls! And I don't wanna force that on her."

"In that case id like to purpose a wager. If you succeed in raising them as the fine human children you spoke of," He raised a single finger, as if to make a point, "you win." He put his hand to his chest. "But if they awaken to their true nature as demons, I win. And if I win I get to claim their lives."

"Fine." Said Shiro, slightly moving his head as if to look back.

"Alright. Now, let's give you a handicap!" He said, snapping his fingers.

Shiro watched as the young male's flames left his body, making their way into the sword.

"What did you do?"

"Oh, nothing. just sealing his demonic power into the sword. It's not much of a bet if he's constantly spouting blue flames everywhere." Mephisto declared, putting his purple gloved hand on his hip.

"I owe you..." Muttered Shiro.

"Oh, there's no need for that. All there's left for me to do is return to the Vatican and say that you destroyed the spawn of Satan." Mephisto walked over to the children and picked up the one in the middle, who was still radiating blue flames before starting to walk out of the cave.

"Wait, what are you gonna do with her?" Asked Shiro, concerned for her safety with the man.

"I was planning to raise her myself," Mephisto said, turning to look at him. "As a demon."

"Is that safe?" Asked Shiro.

"We will be alright." Mephisto continued as he started walking again.

As the two walked away from the small cave, Mephisto looked down at the small bundle and was just able to make out a few dark blue tufts of hair from under the blankets.

"Well then little sister, I believe we're going to get along great."
