"Reynard"

Also known as Rei, Ray, Rae, Rey, or Re. They choose at random. The distinction matters to him, and she will correct you if you get it wrong.

A trickster deity(?) with many forms, but they seem to prefer an anthropomorphic fox. The universe is nauseous at his presence. Every culture seems to have a myth in reference to them; none of those myths agree on anything except the absolute basics. Her terms of address shift randomly and without warning. (Don’t worry, it’s impossible to use the wrong name or terminology for him; they’ve already decided how you’re going to speak of them. She will still correct you if it’s funny, though.)

While it’s clear that they can directly manipulate reality itself, this infinite power is only matched by her equally infinite boredom. He mostly uses the ability to distort the very nature of existence to cause inconvenient, improbable things to happen to the people she thinks would have the funniest reaction to it. He seems disinterested by reality at its macroscopic level, bored at the thought of war, universal heat death, the infinite universe, and other such lofty topics; they’re most content to meddle in small personal affairs. (There is the potential that she has seriously altered the course of the universe, and that they’ve altered continuity so that the changes were retroactively always present to begin with. He seems to find that idea a bit overly convoluted for her liking, though, and says not to worry about it.)

When asked for her past, he gives strange stories. All true, all false.

She was once a mischievous prince who played a cruel joke on a witch, who in retaliation polymorphed him into a fox, unknowingly granting them great magical power. He was an author who became too invested in their work, so that she became trapped within; and without the author, the story itself shattered into uncountable pieces, the winds carrying it far and wide. They’re all in your head, Shinobu, you need to wake up. He’s a strange experiment trapped in a quantum state, only appearing when the fields align “just so”. There was once an enchanted library carrying the original manuscripts for Branch II of “Roman de Renart”; the magic seeped its way into the paper, and the illustrations came to life, releasing Reynard the Fox from the bounds of fiction and into reality. She formed from the gathered thoughts of humankind, the archetypal “trickster” the collective unconscious has unified around for millenia. There was/is/will be someone that fell/falls/will fall into the universe, dissolving into it in all dimensions including time, diluted so thin that they exist in everything and yet remain completely undetectable, with exception of this one discreet point.

Of these stories, they accept and deny all and nothing.

Reynard’s present is much easier understood than her past; they’re simply looking for entertainment. He’s a bit of a layabout, and they don’t like spending more effort than needed, so she often provides “gifts” to very particular individuals. In Shinobu, he saw their old rival Isengrim the Wolf, a rivalry they’ve come to miss since the old mutt’s passing. He granted her wish, and threw in their own wish as a bonus. Shinobu was trying to summon the wolf, after all, might as well give her what she asked for! Shinobu is infuriated with everything about her, and this is exactly what Reynard likes about her.
