Chibiterasu, after the child of Amaterasu, the Japanese Sun Goddess, from the Ōkami series.

The little Elkrin had never been particularly good at acting princely. He may have been considered royalty because of his heritage, his bloodline, but did that matter to him? Not in the slightest.
He often wondered why he should even bother acting princely - After all, what was the point of being young and living life when you couldn't explore, adventure, and enjoy it?
His twin sister, being the princess that she was, often found his behavior peculiar and strange, sometimes even appalling! Why in the world would a prince want to romp about in the woods, chase about the various species living in Eldermore, splash about in the murky streams, and get covered in muck and mud? So improper! Rather foolish, that one. She hoped he would one day grow out of such behavior and become the elegant stag she was sure he was meant to, though she knew in the back of her mind that such a transformation wouldn't happen for who knows how long, assuming it occurred at all.
In the meantime, the little fawn would amuse himself with his little adventures, splashing in puddles, chasing the Rune Dragons, and generally stirring up trouble and making a mess.
It was a warm summer evening when the Elkrin came upon a small stream trickling through the forest. Curiosity overcoming him, he wandered alongside it, following it backwards towards the source, the same way a human child might complete a maze from finish to start in a puzzle book or kids magazine.
He climbed a few small hills as he followed the twisting, curving brook, eventually finding the source of the stream - A small pond with a tiny waterfall flowing from it, leading the water down into the brook.
By the time he'd found the stream, the sun had set, and the moon had risen high above the horizon, leaving trails of moonlight filtering through the leaves of the trees. The surface of the stream reflected the image of the full moon, surrounded by the glows of at least a hundred colorful little firelight flies.
The Elkrin grinned, jumping from his perch on a tiny cliff and into the water below, kicking up a splashing spray that sent the insects scattering lazily away, only to regroup a moment or two later. There he splashed about for who knows how long, caring not for the time and thoroughly enjoying himself - And getting thoroughly soaked in the process.
The firelight flies, having grown tired of the constant splishing and splashing, slowly flew towards the pond, where a much larger light shone from the screen of a human's electronic device.
The human in question was a girl of perhaps sixteen years, certainly no older than that. She sat on a rock, bare feet dangling in the water, and holding a thin, white rectangle that glowed with the light of a game of Peggle. She soon grew bored of the game and pressed a button, flipping through various screens until finally settling on a piano-like application. She tapped it a few times, trying to find the proper notes and keys, then placed it on her lap and began to play.
Perhaps one of the few things the fawn's sister would have approved of him liking was music. The kind didn't matter to him - Genre, lyrics, beat, tempo, origin, length, complexity, instruments - It was all good to him. And so, being young and childish, he climbed up to the pond and listened to the girl and her songs.
For each song she finished, there seemed to be two more left to play, and so he crept ever closer, soon close enough for her to touch, to foolhardy and young to be afraid. She eventually noticed the small Elkrin as the finished one of her songs. She gave a small grin as she finished and turned her head towards him. "Hello there," she said, smiling. "You a fan of music, too?"
The Elkrin tilted his head, unsure of the meaning of those words. He soon realized that she was talking about the noise coming from her machine, and nodded. He looked at the glowing rectangle for a moment, then raised his head back up to view her.
She tilter her head as well, almost like a dog might, as she was a rather odd girl. "Do you want to give it a try or something?" she asked the fawn, who nodded again. "Okay, the, but be careful, alrighty?" She placed the object on the ground by his feet.
The Elkrin sniffed at it for a moment, unsure, then began tapping it with his hooves, leaving streaks of watery mud on the screen as the device screeched out various notes that didn't seem to go together in and shape or form, which wasn't all that surprising - He wasn't human, after all, and the hooves certainly didn't seem to be helping him play very much.
The girl, understanding that fact, grinned at him. "That's not half bad, buddy!" she told him, rubbing his head.
The Elkrin seemed to understand that statement, and in his excitement, began pawing at the machine more vigorously. This wouldn't have been so bad were the ground not slippery, wet, and sloped, and the machine was soon knocked into the water. He shrunk back in surprise, fully expecting the human to be angry with him.
The girl stared into the pond for a moment, then burst out laughing. "Oh, god, not again!" she exclaimed. "That's gotta be the fifth thing I bought from Apple that got wrecked because of water damage!" She shook her head, grinning like an idiot.
The Elkrin stared at her, unsure, then giggled in his own language along with her.
It took her a good several minutes to calm down from he laughing fit. She turned and looked at the little fawn. "You seem pretty friendly for an Elkrin," she commented. "Out of curiosity, would you want to come with me to my place? I've got a piano there, and a ton of other guys you might be able to make friends with!"
The fawn looked at her for a moment, then grinned, nodding.
She smiled. "Great! Come on, I'll show you where it is!" She began to walk off with him, then paused. "By the way, if you don't have a name, is it okay if I call you Chibi? Like, Chibiterasu?"
The fawn nodded again, trotting ahead of her and nodding back at her as if to say 'catch up'.
And from that day forward, the two were friends - Even if his piano skills still weren't particularly great.
