It happened on a morning in the third week, before Saya had fully settled into the household routine.
She had come outside to find Arthur in the yard, and Lyra was there too, sitting on the low wall reading with Tsuki arranged across her shoulders in the customary position — long white body draped along the back of Lyra's neck, small chin resting just below her ear, the silver-tipped twin tails curling loosely. The morning light was good and Tsuki happened to be sitting in it, the white coat catching it cleanly, the faint silver streaks along the tails holding the light with a quality that was somewhere between fur and something that had no specific name.
Saya stopped walking.
Arthur noticed first because Saya stopping while in motion was unusual — she moved with the continuous easy awareness of someone trained to keep moving — and because the expression on her face when she stopped was not the expression she usually wore.
She was staring at Tsuki.
Her tail had gone entirely still. Her ears were forward at maximum angle, the position he associated with something important being processed. Her hands, loose at her sides, had become very still.
'Saya,' he said.
She did not look away from Tsuki. Quietly, carefully, with the specific quality of someone who was not being dramatic but was being very sincere:
'That is a Celestial Fox.'
Lyra looked up from her book. Tsuki, who had been tracking Saya since she appeared, turned her silver eyes toward her fully.
'She's — ' Arthur started.
'A Celestial Fox,' Saya repeated, barely above a whisper. 'My grandmother told me about them. We have stories. Old ones. They're divine messengers — they carry light between the spirit world and this one. My tribe has never seen one. No living member of my tribe has ever seen one.' She paused. 'My grandmother said if you ever encountered one you should bow.'
Tsuki looked at Saya with silver eyes that were, at this moment, doing absolutely nothing to make this situation less credible. She was sitting in morning light with her twin tails catching it like something out of a woodblock print and her posture had the quality it always had, which was the quality of something that had been here longer than the conversation and would continue to be here after it.
'She's my familiar,' Lyra said, slightly uncertain about how to deliver this information given the expression on Saya's face.
'Your — '
'Arthur made her.'
Saya turned to look at Arthur with an expression that had added a new layer to the existing one.
'You made a Celestial Fox,' she said.
'I made a construct with a fox elemental design and a light affinity and — ' He looked at Tsuki. Tsuki looked back at him with the patient silver gaze she had been looking at him with since the day he built her. 'She's a familiar. That's all.'
Tsuki held his gaze for a moment.
Then, with unhurried dignity, she turned back to the morning light.
Arthur stood in the yard and thought about this.
He thought about the fox deity legends that appeared in approximately sixty percent of the fantasy literature he had consumed in his previous life. The nine-tailed fox. The divine messenger. The celestial creature that carried light between worlds. He thought about how often those legends showed up, across different stories, different authors, different worlds — always the white fox, always the silver tails, always the light.
He thought about Tsuki's design, which he had arrived at from his own instincts: pure white, silver streaks, twin tails that would grow to nine, wind and light affinity woven into her at the foundational level.
He thought: I designed her from the stories. The stories existed because someone saw something like her and wrote about it. Which meant either the stories had informed the world's legends and the world's legends were now being reflected back at him, or the stories from his previous life had been — in some form, at some level — drawing on something real.
Light novels as biography.
The thought arrived with the specific weight of something that was either a very interesting coincidence or a very unsettling one, and he filed it in the category of questions that probably didn't have an answer but were worth keeping.
He looked at Tsuki.
Tsuki was sitting in the morning light with nine future tails implied in her current two, and she was not helping.
'She's a familiar,' he said again, to no one in particular.
'Of course,' Saya said. She had not entirely returned to her normal register. She looked at Tsuki with the specific quality of someone who had been told something was an ordinary thing and had filed this information while privately maintaining their original position.
Lyra looked at Tsuki. Tsuki looked at the morning.
'Is she at least — ' Saya tried. 'Does she know? About the stories?'
'She's seven months old,' Arthur said.
Tsuki chose this moment to stand, stretch with complete commitment, walk the length of Lyra's shoulders, step off onto the wall, and sit in the precise center of the morning light with her twin tails arranged behind her in a way that was — it had to be said — compositionally ideal.
Everyone looked at her.
Tsuki looked at nothing in particular, in the specific direction of the horizon.
Arthur thought: I am not getting a straight answer out of this familiar.
He thought: this is because I built her personality and whatever is happening right now is something I apparently built in without knowing I was building it in.
He thought: the light novels were probably not biographies. Probably.
He decided to go have breakfast.
