Disclaimer: I don't own anything, except the OCs, and my version of the fandom universe

Author's Note: To all my readers (especially fans of my other works), I know I should be focusing on my other stories, but this idea has been in my head for a while. For anyone that has read my previous works, this story ties in with my Darkstalkers fanfics in that it is set in the same universe. However, for anyone who might be wondering, this is set several centuries after my previous fics that feature this universe, and as such, most characters (outside of Familiar of Zero characters) will be OCs.

Prologue: Destiny's Call

Tristain Magical Academy, Helkagenia

Louise Françoise Le Blanc de La Vallière woke up with the sunlight shining into her room. Today was a very important day for her, the day she would show every single one of her classmates she was not as useless as they thought she was. And of course that would help prove the same thing to her family. As such, she was in a very good mood despite how nervous she had felt the night before.

Now one might wonder why she felt like she needed to prove herself like this. The reason for this, is because of the world she was born in. In this world, the hierarchy is that of Nobles and Commoners, with Nobles being signified by their use of magic. However, for some reason, despite being born a Noble, Louise was for the life of her, unable to cast a spell. More precisely, she is unable to cast a proper spell without it blowing up in her face. A fact that has sadly earned her the derogatory title of 'Louise The Zero' by both her peers and even her own family.

She dressed up in her school uniform and combed her curly pink hair with dedication before exiting her room to get some breakfast at the dining hall of the Tristain Academy of Magic. Climbing down the stairs of the dorm tower until she got down to the grounds and walking towards the tall tower in the middle of the school where she attended her classes and had her meals along with the rest of the students.

After breakfast she and the other students gathered out at the Academy Grounds, as she felt all the more determined to obtain the greatest familiar ever seen at the academy…as long as she didn't blow it up, of course. She sighed as she walked alongside all of her class towards the Academy Grounds where the summoning rituals for the Second Year Students supervised by their teacher Jean Colbert were held.

After about half an hour later it was her turn and her good mood had shifted into nervousness once more, especially after her long time rival Kirche Zerbst had summoned an impressive looking Fire Lizard and Tabitha, a quiet bluenette friend of Kirche, had summoned a Wind Dragon of all things.

Louise stepped forward, all eyes looking at her with scorn, ready to laugh at her if she failed. But she wasn't going to let them, her determination setting in as she started chanting the summoning spell. Little did she know that somewhere in the universe, or rather, the Multi-verse, her Familiar was preparing himself as well…

Meanwhile, Radiant Garden

The morning started out relatively normally for Saito (age 16). After getting up at the crack of dawn, he followed up with his morning exercise of jogging around the block for 50 laps, followed by Kata and Martial Arts exercises, topped off with meditation before breakfast.

"Morning, Ototou-chan," came the voice of his big sister, Saki (age 19). She was a young woman of average height with tanned skin and deep blue eyes, with her most distinguishing feature being the cat ears on her head, cat paws in place of her hands and feet, cat tail, and fur lines that covered her body in an…advantageous manner, though it was covered by the simple white dress she was wearing.

Morning, Nee-san. Where's Nii-san?" Saito greeted.

"Oh? Kazu-nii had to attend an emergency defense meeting, so he left a few minutes ago," Saki answered. Their older brother, Kazuki (Kazu for short) (age 24), worked as part of the town's defense force so he often wasn't home.

"Again, huh?" Saito sighed.

"By the way, a letter came in today, and it's for you," Saki suddenly said, her voice turning serious as she handed him a letter.

"The Infinity Seal? That means this is from…" Saito's eyes widened.

"Yes. It's from cousin Zane," Saki nodded, as Saito opened the letter.

"So it's finally come, huh?" Saito said with wide eyes as he lowered the letter.

"Yeah…" Saki frowned. "Saito…take care of yourself."

"I will, nee-san. I'll…I'll miss you and nii-san," Saito nodded with a bit of sadness in his tone, before his features turned into determination.

Several hours later, Saito (now dressed in his armor) was now standing in the middle of a mystic array that had been prepared for this day. Earlier, he had spent the day calling up friends and family, hanging out, and ultimately saying his farewells, knowing that he might not see them again after this day. Around him (though still outside of the array) stood several people who were chanting in preparation for the ceremony, while nearby, his brother and sister stood waiting to see him off along with several of his cousins and friends (he was sad to note that his two best friends and teammates were absent).

As the chanting grew faster, one of his cousins, Zane, raised his hands which were glowing with power.

"Saito. The time has come. Today the path to your destiny will reveal itself, as you will be called to it. Do you, Saito Hiraga Talbain, accept this call?" Zane asked.

"I do," Saito answered solemnly.

"Then…" Zane was about to say, when someone interrupted him.

"Hold it! Hold it right there!" came a male voice.

Turning to the source, Saito was surprised to his best friends, Kevin and Mika, running towards them, with both of them carry what Saito recognized as the same type of bag one would use when on a long journey, as those bags (like the one he had on him right now) had an enchantment casted on them to allow them to carry far-far-far more then what they looked like they could carry (essentially a 'Hammer Space'), as well as the fact that they were dressed in what they usually wore when they were going to fight.

"Stop. Stop right there…" Mika panted, before she and Kevin entered the array.

"What is going on here?" Zane asked in annoyance.

"Yeah…sorry to interrupt, but we're coming along too!" Kevin stated.

"And you two didn't tell me this earlier, because…?" Saito asked in an un-amused tone.

"That's not important right now!" Zane quickly cut in. "We must finish the ceremony now. You two are welcome to come with him, so quickly join hands and repeat after me!" Zane barked, as the three of them obeyed.

Just as they were about to start, Saito began hearing something in his head, but ignored it in order to finish the ritual.

(For the next lines, italic words will be Louise's summoning, while words in bold will be Saito's chanting)

I beg of you…

I hear you…

My servant who lives somewhere in the universe!

You who pleads with heart and soul!

Oh sacred, beautiful and strong familiar spirit!

To this I swear, my body shall serve, yet my soul shall remain!

I desire and here I plead from my heart!

With this oath…

Answer to my guidance!

I hear your wish and accept your call!

(end chanting)

With that, a portal appeared where the array once was, and the three of them vanished.

Tristan Magical Academy, Helkagenia

To say that Louise was ecstatic would be a complete understatement. Just seconds ago, she had began summoning her familiar. "My name is Louise Françoise Le Blanc de la Vallière. Pentagon of the five elemental power, heed my summoning... and bring forth...my Familiar!" was what she said, but deep down, she was pleading and begging with all her heart that she be given a familiar. What came next was a chant that came in answer to her own, from a voice that seemed to be both strong yet gentle at the same time. She could feel it. Her familiar had heard her call and was coming, and every second she felt it coming closer, until…

Booooom!

Another explosion…

"Damn it, Louise! Can't you do anything other than cause explosions?!"

"You should just quit, Zero!"

Were among the jeers/angry shouts that her classmates shouted, yet Louise ignored them. Instead, she was more focused on the cloud of smoke that her explosion had caused. Where was her familiar? She knew she had felt it, yet she couldn't see it. She even worried that it might have been killed in the explosion.

The jeers continued, but abruptly died down when the smoke dissipated, revealing Louise's familiar. It was a wolf, but not like any wolf they had ever seen, for no regular wolf stood upright like a human. Standing at nearly twice her height with mixture of deep azure (covering most of the body) and snow white (only around the muzzle, chest, arms, and feet) colored fur, was a humanoid wolf. A werewolf to be precise (not that they knew this). It was dressed in light leather armor that was colored a dark green color, with metal shoulder guards, leather gauntlets and dark colored long pants (think Lancer from Fate/Zero). In its right hand (paw?) was an elegant looking spear with a tip that looked like it was made of gold, with a deep red shaft.

Everyone was stunned silent at the sight of what Louise, the girl they all perceived a failure, summoned, though some wondered if it was even going to allow Louise to finish the ritual. Louise herself was unsure what to feel as she gazed upon her intended familiar. One side of her was terrified of the creature's appearance, as one look already told her that it could easily shred her apart if it so chose, while another part of her was overjoyed that she had been granted her wish, for while she doubted her familiar could be considered sacred, there was no doubt in her mind that it was strong (don't need to explain this one) and beautiful (the azure fur is exotic, borderline majestic).

To everyone's surprise (at least to those that expected Louise to fail somehow), the wolf gazed towards Louise, before it knelt down on one knee, bringing it to slightly below her height, whilst giving her a clear look of its eyes which were as blue as a clear sky (extra points to the beautiful part), before laying down its spear, and placing its right arm over its chest (reminiscent of a knight swearing loyalty), before dropping the largest bombshell of all. It spoke. "I heard your wish, I headed your call, and I have come. I ask of you. Are you my master?" it said as it looked Louise in the eye.
