This is a strange crossover that occurred to me after watching a few old cartoon ops on YouTube. Basically what happened is that Sunni of Disney's Adventures of the Gummi Bears is the sole remaining Gummi Bear of Gummi Glen, that's been around since before Konoha was even a dream in the eyes of ninja. I put the lives of the Gummis as being somewhere near a few hundred of years. Due to a barely remembered episode, I've put a somewhat halt on Sunni's apparent age, so that she's roughly the same physical age as in the show.
Don't own the Gummi Bears, nor Naruto.
Naruto was on the way from the mobs again, this time he went into the forests, beyond the rocky area that was forbidden for any to enter. He couldn't see why, they were actually a bunch of really cool buildings with these metal suits, cool swords, and all those books behind that invisible wall!
But he had never been beyond them before today, so since he'd been chased past his usual hideout, he decided to do a little exploring. Climbing past one of the trees, he let out a shout as the entire side of the trunk collapsed in on itself and sent him tumbled down into what appeared to be a cozy, if dusty, living room. Looking around he noticed a few indicators that someone had been living here not too long ago, and so he called out, "Hello? Anyone here? I kinda just fell in your front door!"
Hearing a faint sound through one of the doors, he started heading towards it so he could see if someone lived here. Knocking softly on the door, he listened for movement on the other side, and was almost surprised when he heard someone approaching the door. Stepping back he blinked as a short bear appeared in front of him, a short blond bear with a green dress on, a short blond bear with a green dress on and a giant forelock over her forehead. Maybe he should stop focusing on the short bear's appearance. Well short for a bear, since she was about his height. "Umm... h... hi... I'm Sunni..."
"Hey Sunni, I'm Naruto! Are you all alone here?" Naruto asked curiously, looking at the strangely void living quarters. It looked like there should be others here, but there was no one else around.
"N... no... the others are j... just out..." Sunni protested weakly as she rubbed her arm quietly. "They... they should be back soon. Gumhalla isn't far..."
"Oh, well I'm sorry about barging in Sunni... how do I get out of here?" Naruto asked, figuring the girl-bear-thingie wanted to be left alone. As he was looking around, he couldn't be faulted for missing how her eyes widened in what looked almost like terror, and her body stiffened fearfully.
"Go? B... but you just got here, how about some tea? I'm sure Grammi left some of her cookies around too... Just stay for a bit and you can meet everyone..." Sunni offered suddenly as she nearly pushed Naruto into a chair by the empty fireplace. It was as she was turning away that he noticed her eyes were rimmed with a redness he'd only seen when he was crying late at night.
Deciding to stay for a little while with the obviously lonely bear, she seemed young and this had to be her first time alone like this. So it wouldn't be too bad to stick around for a little while. Besides, he'd never had cookies before, and all the kids said they were great, so why not have some?
It was while he was waiting for her, he saw a faded photograph with a group of six bears including Sunni all posed together. There were several colors among all of them from pink to purple, even an orange one. If he'd been asked by anyone, he would have commented that for some odd reason they reminded him of his academy class, but he couldn't think of why.
Hearing the bear's return, he blinked as she set out a pair of cups with handles, on small plates, and a metal pot with a pour spout on it. "Sorry about this, but we only have Gummi Berry tea left... don't worry it won't do anything weird, Grammi made sure of that when she taught me the recipe..."
"That's fine, it smells great!" Naruto assured the girl, while taking the cup of tea she poured for him. Taking a sip, he watched as she busied her hands with tidying up a little, as though she was nervous or uneasy about something. Taking a moment to swallow the sweet tea, he pointed at the picture he'd been looking at earlier. "Are those the others?"
Sunni's head snapped to the faded picture, and then she did something Naruto hadn't expected. Her eyes welled up with tears, and she curled up into a sitting ball on her seat. "Yes... t...that's them..."
Now, Naruto had never grown up with what anyone might consider a normal family life, but he could see that them not being around was hurting her. Thinking quickly, he picked out what he hoped would cheer her up. "Hey, how about you come over to my place for a while? Just leave a note for them or something..."
"SURE! That'd be great... but... other humans can't see me... it's a rule of ours..." Sunni explained while fidgeting in her seat nervously. Naruto blinked slowly as her nervousness became almost palpable.
It was at that moment that he got one of the strangest ideas he'd ever had, and figured it might just work. "Why don't I just say you're my ninkuma or something?" Naruto asked curiously as she looked at him as though he was completely insane. "Well you're a bear, and not one of the usual ones, so all we have to is say that you're my ninja companion and no one'll even give you a second thought!"
"T...they do that now?" Sunni asked in shock, her tea completely forgotten.
"Oh yeah, all the time. I saw one girl with a pack of three wolf-like dogs," Naruto explained with a laugh as he downed the tea, feeling a strange sensation wash over him. It would be so easy to pull this off, and if she didn't like it, she could just disappear, and he'd make some story up to cover for it. "What do you say? I mean, we'd just have to talk to the old man, and he'd smooth everything over. Whatcha say? Wanna just hang out at my place for a while?"
"T...That sounds great!" Sunni answered cheerfully as she hugged the boy that had suddenly offered her freedom from her loneliness. The others had been gone for so long.
After Granni and Zummi passed away in their sleep, the others had gone take them to Gumhalla, the traditional burial grounds of the Gummi Bears, and then took Cubbi on his coming of age quest. That had been nearly five-hundred years ago. She had stayed behind to continue brewing the Gummy-berry juice and maintaining the bushes. After all, if they weren't picked at least every five years, they would die out and to grow new ones would take at least thirty years before they were able to be picked.
In that time they would run out of their surplus juice, and most likely suffered some horrible fate because of it. She had just picked and bottled the last batch of juice for the year, so she could take a short vacation. The others would understand, and she wouldn't be exposed thanks to Naruto's plan. All she had to do was not use any juice in front of humans, or any of the magic Zummi had taught her before he died. She could also keep the Great Book of Gummi Magic at Gummi Glen and keep that secret too.
Finishing their tea and cookies, the pair set off on the journey back to the village of Konoha as Naruto referred to it, past what Sunni called the ruins of Dunwyn. A once mighty and peace loving kingdom that had been destroyed after her friend Calla had passed on from old age. After they got past the gate guards, with orders to see the Hokage, she found out much that Naruto hadn't mentioned.
It seemed that her loneliness wasn't the only one the boy had cured that day. If she had anything to say about it, he was never going to be lonely again.
