Prologue

Earth, 1994:

Tsukino Usagi, Sailor Moon, struggles to breath as she lays impaled upon the spire of a tv antenna. Why, why had they turned on her like this? All she had wanted was to be free to make her own choices. Tokyo had been torn up from their battle but, at least she'd protected the civilians. " Onegai, let me have a loving family, let me finally be free of my obligations as Moon Princess. Let me be allowed to choose in all things for myself. "

Queen Aurista of Pluto and Queen Hadia of Saturn answer their hime's call. With the help of Amaterasu they finally find a place where she can have what she had requested in her dying breath, she'd face hardship of course, but, she would have a loving family and be free to choose for herself in all things.

Mobius, 3220:

Jules Hedgehog sighs as he returns home, his head was pounding, which made sense since he'd been an idiot and gotten drunk after having a huge fight with his wife. Then waking up in a strange female feline's bed. Hopefully Bernie was in a forgiving mood, especially since they had Sonic to consider. Bernie looks at her husband, he almost looked worse than when he had stormed out last night. Chuck was currently watching Sonic Maurice Hedgehog, that little boy of hers certainly could crawl fast. " Jules, what happened? "

" I got drunk and did something stupid, Bernie. "

That statement told her a lot, " You weren't thinking straight when you left then getting drunk just compounded the issue. You're forgiven. "

Bernie would think nothing more on this until their son was almost four. A new family had moved in next door and Sonic was out with Muttski and his father. Bernie's highly attuned ears picked up the barely discernible sound of whimpering. The pained whimpering of a child, the mother in Bernie just couldn't ignore that. She follows the sound next door and sees a small kitten, tabby style mostly colored silver with blue stripes. It was the pony tail that gave away her hedgehog heritage as it was currently stiff and sharp. Bernie inhales sharply when she sees the color of the kitten's eyes, just like Jules'.

Bernadette Hedgehog stands up to her full height after checking on the kit, you could almost see her aura of righteous anger ignited when Felicia Felidae returns from her errands. The feline actually steps back in fear, " You will sign custody of her over to my husband and myself or so help me everyone will know how you treat your own kit. "

Bernie's quills had stiffened and sharpened dangerously, the very picture of feminine ire at that very moment. She would never allow anyone to treat her son like this, nor would she allow his half-sister to suffer like this if she could help it. Two hours later Bernie and Jules Hedgehog have custody of Seraphina Felidae. The kit had also been checked out by Doctor Horatio Quack. She had been given a mostly clean bill of health. She was malnourished and suffering from exhaustion. Dr. Quack and Queen Alicia Acorn had managed to hush everything up for the sake of the kit involved.

Explaining everything to Sonic had been trying but, surprisingly Sera, as the kit preferred, flinching every time she was called Seraphina gave that away, got along well with Sonic. Then again he was around her size, she had learned adults weren't to be trusted at the hands of her own mother and her step-father.

Soon enough she was climbing onto her brother at every opportunity not that Sonic really minded. He actually enjoyed having a little sister and imagine the surprise of the adult hedgehogs when Sera also showed she had the same speed as Sonic. Chuck worked on developing a pair of friction free shoes for her as well, where Sonic's were red and white hers were blue and silver with red buckles. Sera also wore a purple t-shirt and black shorts with red socks and silver fingerless gloves with blue cuffs.

Bernie watches as her children play together though at times she swore she saw the shadows move. She had no way of knowing that they actually were under her step-daughter's direction and that Sonic was helping her learn how to control it.

Knothole, four years later:

Sera Felidae rolls her shoulders even as she spins away from Princess sally Acorn's attack. Sonic chuckles as he watches his little sister spar with Sally. Sera was the only one that was allowed to do field work, mostly because her hearing was that good. It had taken Rotor a while to come up with a way to protect her sensitive hearing. Sera had control over sound and shadows, though only Sonic knew about the shadows since she practiced those abilities on him. She also had the speed factor though she only used it when it was just them.

You only noticed her hedgehog heritage if you looked closely, Sera slides under one of Sally's kicks and immediately switches momentum to kick Sally's feet out from under her. The seven year old kitten was quick to pin the Leader of the Freedom Fighters. Sally taps the ground disgruntled, she should know better than to get into a fight with a cat. Sonic helps them both up and gives his little sister a cursory onceover, " You both did well, Sal, don't feel bad, she's just naturally more agile. "

Sera scrambles up onto his shoulders and Sonic rolls his eyes, once she'd recovered from living with her mother she had climbed on him all the time, still did. " Comfortable, Sera? "

" I am, yes. " Sera retorts.

Sonic gives a long suffering sigh at this and then the three of them start discussing picture frames for the map. Sera cocks her head to the side before flicking the earrings Rotor had devised to protect Sera's hearing. " 'Twan's in trouble. Buttnik's created a new robotic plant and it's seeded throughout the forest. " Sera says.

Sonic sighs, " Down, Sera, I won't be going far, just getting 'Twan out of trouble, okay. "

Sera looks down at her brown eyed brother and reads the truth in them. She climbs down and gives him his patented I'm Waiting stare with the foot tapping included. Sonic blinks at this and grabs Sally before racing off, wondering when his little sister picked that up from him. Thanks to Tails they destroyed the Krudzu as Buttnik was calling it that came in on 'Twan and Mother Nature took care of the rest.

Sera once again is on Sonic's shoulders, not wanting to let him get away. " Why do you let her climb on you like that? " Rotor asks.

" She's not harming nothing, besides, this keeps her out of trouble. " Sonic states.

Sera raps him lightly on the head, " All right, coming from me that's ironic but, you are my responsibility. "

" She is? " Sally asks, none of them had known exactly why Sonic kept the kitten so close.

" Legally my parents have custody of her. " Sonic says, telling the truth while leaving out the fact that Sera was his half-sister.

With that news stunning the others Sonic takes off with Sera and Tails, time to have some fun.
