Author's note: Welcome. A quick note about language use: since this is set in Japan, many of their naming conventions will be used here. For instance, this will include honorifics, some terminology (although it shouldn't be too much of an issue) and surname-before-firstname conventions. Otherwise, I hope you enjoy.

Chapter 1: A False Negative
In the rural areas of coastal Japan, a short distance off from the town of Kushimoto in the Wakayama Prefecture, stands a small cliff-side building in the style of a traditional temple. From this temple, a bright blue light would often shoot out over the sea. Not many humans cared for what went on inside, and those that did quickly lost interest. Surrounded by woods, almost nobody would disturb this strange temple, and anyone who did stray close to it often landed up somewhere in the streets of Osaka or Kyoto in little more than a vegetative state.
There was one exception to these people: a small emerald green-eyed white-haired boy who lived in the seaside temple itself. His head, with his hair spreading so it gave the impression of an attached silver fan, would always wonder why the lights were shooting out over the sea, and he wondered if it had anything to do with his oldest sister telling him to be in bed. His room, one floor above the ground level of the cliff, always faced towards the forest, but when he tried to sleep, he would hear crackling and humming. Running to the lounge, on the same floor but with a glass dome stretching from the ceiling halfway to the floor to create a feeling of a balcony, he would always see the bright blue jets shooting over the sea, giving a slight ocean view in the blackness of the night.
His name was Sora, named after the sky. And like the sky, according to the eldest sister Misaki, he had absolutely nothing noteworthy in himself. Years of his life went by, and her sapphire-eyed visage looked at him with more and more disappointment. Her free-flowing white hair extended down to the mid-point of her back, yet underneath all those locks of hair was always a feeling of disdain: one that many traditionalists of her kind would feel when looking upon the people they called 'Heimin'. The Heimin, unlike Misaki and the younger sister Rin, possessed no magical ability whatsoever and made up the majority of Japan's population, although in her eyes, Sora appeared to be just as much of an embarrassment. He was born to two wizarding parents, yet for the ten years of his life so far, he had displayed no magical abilities of any kind.
The displeasure that Misaki felt towards him often materialised as the word 'weak Kakushigo, illegitimate child', and she, ten years his elder, would treat him in much the same way a controlling parent would treat an underperforming child or a defective product. Rin, with ruby-red eyes, a white shoulder-length ponytail and a more tolerant demeanour when it came to their youngest sibling, told him that Kakushigo are wizard offspring who have no magical abilities of their own, although she herself always shied away from using that word. She was the only one of the two sisters to try spend time with Sora, four years her junior, although how they spent time together was often questionable: he was often hiding from her, and at some point an object near him would burst into flame and shock him into revealing himself
After another night of looking at the blue light shining over the sea, Sora woke up to a persistent call of "Sora-kun, get up!" from Rin by his bedside. Opening his eyes, he found her face hovering over his, and there was quite a sinister look in it, like she was wanting to 'play'.
"Listen, Misa-chan is just getting dressed, but we need to run into town for a few errands, Kay, Sora-kun?"
"Yes, Rin-nee-chan. For what?"
"Getting some new clothes and a bit of food. I'll see if we can bring back some takoyaki for you. Don't get too bored, okay?"
"Nee-chan?"
"I know how boring it can be by yourself, but I promise we'll have some fun when I get back."
"Rin! Where are you?" another voice yelled from elsewhere in the house.
"Coming, Misa-chan!" With that, Rin ran out of Sora's small room, and her steps continued to echo on the wooden floors of the upper level.
Looking around, Sora saw that a small head with slitted orbs for eyes was peering over his windowsill. "It's okay, you can come out now."
The head pulled itself into his room, followed by a long brown slithering body. "Why do you talk to me ssso casually?" it asked.
"You're the only company I have aside from my sisters."
"You do not cooperate withhh your brood?"
"Misaki-nee-chan always calls me a useless Kakushigo, and being around Rin-nee-chan hurts sometimes. I don't see anyone or anything else."
"She lies."
"What makes you say that, onii-san?"
"SORA!" Misaki's voice boomed from downstairs.
"Sorry, onii-san, I have to go. I will come back later though."
"I musssst go to find food. I do not know if we will sssee each other a sssecond time."
Sora quickly ran out of his room and saw Misaki and Rin waiting. The former was in an electric blue suit, and the latter in a basic red shirt and black shorts. "Sora, we are leaving for a while. You know what to do."
"Yes, Misaki-nee-chan. I am not to go outside, and if anyone knocks at the door, I am not to let them in. I also need to make your beds before you get back."
"Good. Rin, let's go."
Rin grabbed onto Misaki's left arm, and a second later, they vanished with a loud crack. Now Sora could finish his conversation with his onii-san, but when he got back, he found him gone. Peering out his window, he didn't see him. The only thing he saw was a woman with a black bikini top, long, sleek, seaweed-green hair and a purple line descending down her cheeks from each of her yellow slit-pupiled eyes… looking back up at him with a wicked smirk across her face.
