Prologue:
When people think Satan, they generally imagine an ugly fellow who plots torture and mayhem for humanity. In some worlds that is in fact the case, but in this one they would be surprised to find out that the rather handsome and bored man sitting behind an ornate desk was the Devil himself, considering he was known for being kindhearted to everyone he meets, unless they threaten his sister, but that is another thing entirely. His wife and maid Grayfia had to go home to take care of something, and so she left him at his office to finish the paperwork.
He chuckled, knowing the look she will give him when she finds out that he was shirking his duty in doing the paperwork. The man sighed as he tried to figure out what to do. He snapped his fingers as he figured out what he could do. He got out his old list of contracts on his Devil-berry and looked for the exact details of a unique case that he had been hearing a lot about recently that he had helped with quite a few years ago.
"Saotome Nodoka, that is what her name was."
The Devil smirked as he called upon a special magic device that was stored on his wall that allowed him to see what his contractors were up to, not that he maintained many, because most people who managed to summon him only wanted the world to be destroyed or other violent things, and he really did not want his sister to know the horror of war.
The screen on the device lit up and showed him a rather interesting scene. It looked like it was supposed to be a western style wedding, but to say a tornado had hit it would be an insult to the kind of damage tornadoes could do. At the center of all the chaos was his quarry, the child that he had helped Nodoka conceive when he had used experimental magic to help Nodoka and Genma have a child. What shocked him was the state the girl was in, and with her bright red hair and tear-filled blue eyes, she reminded him very strongly of his sister. So strong was the resemblance that he instantly looked up all the information he could on her, and he became even more enraged the more he read about the apparent boy's life.
In the end he almost ended up destroying the desk he was sitting at through sheer presence alone. Unfortunately he could not interfere with the child directly because that was against the terms of the contract he had made with the boy's mother. He started thinking of the different angles he could come at for it, but he was drawing a blank, until he looked absently at his desk, which had the first summoning flyer on it that his sister had ever made. The wheels turned in his mind while he debated the pros and cons of the situation, and he nodded decisively in the end. He figured that there was no better cause to which that flyer could be put towards, than figuring out a way to help the quasi-leader of the Nerima Wrecking Crew in his predicament. He used a simple spell to teleport the flyer into the boy's pocket and then closed everything as he sighed.
"I really do get payed too much if I could let a contract like that get that out of hand."
