It had just been a normal day, like any other. Hiyori was helping Yukine with homework, and Yato was lazing about, getting the occasional yell from Daikoku to "stop being a freeloader and go do work".
"See Yukine-Kun? You say it like this." Hiyori slowly repeated the phrase written on her old textbook, and Yukne copied her. "Good! You're getting there!" She smiled, giving the young regalia a high-five.
Yato popped his eyes open and grinned proudly. "You're a good teacher Hiyori."
At that moment Yato's phone rang, and he clicked the answer button. "Delivery god Ya-"
"Look outside, Yato-chan!" Kofuku's worried voice came from the other end of the line. She was shopping in town, since Daikoku had granted her a rare day out.
Outside was a massive storm, made of several dozen phantoms. It looked like a horrendous mass of black clouds, only visible to regalia, their masters, and people like Hiyori who lived between the two worlds.
"Yukine, let's go! We've got a job to do!" Yato sprang to his feet and ran outside, Yukine close behind. Hiyori followed along too, her soul slipping out of her body to reveal her purpleish-pink lifeline cord.
"Come, Sekki!" Yukine turned into twin blades, and Yato began to slay the phantoms, but it was a monstrous task. Several times the young god was beaten every which way, and they just kept coming.
"Yato!" Hiyori watched the tense battle, when something caught the corner of her eye. It was a small, glowing dot, about the size of a human hand. She recognized it immediately. "A Regalia's soul!" She thought, and called out, "Yato! There's an uncorrupted Regalia over there!"
Yato risked a moment to glance over at the soul, and mumbled, "Young, a little younger than Yukine, a girl."
Yukine, still in katana form, said to Yato, "Save her!"
"We have to take care of this storm first!" Yato replied, taking another phantom down in the process.
"But her soul might get corrupted!" Yukine argued, "And she'd just be another phantom we'd have to destroy!"
Yato sighed and nodded, taking position in front of the soul. "You, with nowhere to go, and nowhere to return, I shall grant you a place to belong. Bearing a posthumous name, you shall remain here. With this name and its alternate, I use my life to make you a Regalia! You are Mine! As a Regalia, Takane! Come, Taki!"
The soul glowed for a moment, then transformed into a flute. Yato grinned, and admired the silver instrument.
"A flute?" Yukine asked, "How is that a weapon?"
"It's not. Regalia don't have to be weapons, remember? Tomone is a smoking pipe."
"Oh, that's right." Yukine said, then added, "We'd better take care of the rest of that storm."
"Right." Yato turned to Hiyori, who was close by. "Can you hold her for a minute? I'd rather not have her revert until after this battle is over, and I've got my hands full with Yukine."
"Sure." Hiyori gently took the newly found Regalia into her hands, and smiled. "She's such a pretty flute."
"That she is. Let's go, Yukine!"
It took about an hour, but finally, the storm was vanquished. Yato called for Yukine to revert, and walked home with Hiyori.
"I wonder what she'll be like?" Hiyori thought aloud, smiling.
"Let's find out, shall we?" Yato held out his hand for the flute, and said, "Revert, Mine."
In front of the small group, suddenly the flute became a small girl, maybe about a year younger than Yukine, with sleek black hair, and hazel eyes. She wore the same robes that Yukine had once worn, and she looked very shy and meek.
"Where am I? What's going on? Who are you?" She asked softly, and she was trembling.
Yato calmly held out his hands, and said soothingly, "Don't worry, you're safe now. I'm Yato, your master. This is Yukine, my Regalia. You are now my Regalia as well. We are family."
Mine looked between Yukine and Yato, then ran to both of them and clutched them tightly, shaking hard. "Family?" She whispered, looking up into Yato's ocean blue eyes.
"Yes, family." He confirmed softly. "Now let's go home."
A/N I've edited this chapter a little, added the proper honorifics as well as added a line break where there is a time-skip
