A different kind of fanfiction than I usually do. A couple of OCs need to go on a quest and we see Hiei, Kurama, and Yusuke in a completely different light in this version. I had fun writing it so I hope you enjoy. Let me know what you think!
"Beautiful necklace," Amethyst said to her identical twin sister, "where did you get it?"
"Out of some box in the back of grandpa's closet," Sapphire replied, "it's sapphire, just like me!"
Amethyst replied, "I can see that. Can I wear it? I want to try it on!" She forcefully took it off of her sister's neck and placed it on her own.
Sapphire shouted, "Careful! Hey it looks good on you."
"Of course it does," she replied, "if it looks good on you it looks good on me, that's how ideniticalness works, silly." She looked down at the bright blue necklace around her neck and how it glistened in the small beams of sunlight that peaked out from behind the leaves of the tree they were sitting under.
"I knew that," Sapphire replied.
"Sapphire! Amethyst!" their grandfather's voice called from inside the tree they called home.
The girls stood up. "The necklace!" Sapphire whispered. Amethyst took it off her neck but dropped it, her sister stopped her from picking it up as their grandpa appeared.
He looked at the girls up and down, noticing their sudden strange behavior. Instead of saying anything about that he said, "Breakfast is just about ready ladies, come inside." They both stepped forward and heard a crunch under their feet.
"No!" Amethyst said, "The necklace!"
"The what?" their grandpa asked.
The girls picked up the pieces of the broken necklace. Sapphire explained, "I got this out of a box in your closet grandpa, I'm sorry."
"That necklace," he said, "I had it hidden away for when you became 18, Sapphire, since it's a sapphire like you. I have an amethyst bracelet for you dear. What a tradegy." He looked at the pieces completely heartbroken.
"Grandpa what's wrong?" Amethyst asked, "I'm sorry."
He explained, "I got this for your grandmother when I was about your age and we were just getting to know each other. I wanted to prove how brave I was so I trekked through horrors just find her this beautiful stone and put it on a necklace."
Sapphire asked, "What kind of horrors?"
"The Twisted River is one of them, you have to get passed a demon called a mazuku," their grandpa said, "then you have to go through a demon fox's teritory before meeting a fire demon, the guardian of the Forest of Giants. At the end of that is a cavern full of sapphire and amethyst stones."
Amethyst asked, "You have to go into demon teritory in order to find that beautiful stone?"
"Of course," he replied, "they have all of the good treasures."
"We'll do it!" Sapphire said, "I want a sapphire necklace when I turn 18."
"Are you crazy?" her grandpa said, "Those demons will kill you so fast."
"But grandpa," Amethyst said, "you said you were our age, 14, when you through those things. I think we can take it, besides, there's two of us and there was only one of you when you did it. I think we can handle it."
He said nervously, "I don't know."
Sapphire replied, "She's right grandpa. Besides, now we get to prove how brave we are to you."
"Come inside," he answered.
Their grandpa sat at the wooden table in the middle of the kitchen and said, "It's been many decades since I've been through demon teritory but since demons live for centuries I'm sure not much has changed. The first demon you meet is a mazuku."
Amethyst said, "That ones powerful, right?"
"Yes," he continued, "very. However, this demon, his name is Yusuke Urameshi. He was once human many, many years ago. He became a demon through death when one of his ancestor's DNA was activated. Yusuke can be quite friendly to humans, so I don't think you'll have any trouble with him. He'll bring you to his boat and navigate you through the Twisted River." He took out a map and showed them.
"That really is a twisty river, look at that," Sapphire noted.
He said, "That's where the name comes from. Here is where you'll want to stop, Yusuke will know that of course, he guides people all the time on his boat. Anyway, here you'll meet a demon fox named Yoko Kurama. I've heard in recent years he's become quite tame, but it could be all an act to trap more humans."
"What does he do to the humans he traps?" Amethyst asked.
"Takes everything they own," he explained, "foxes can be quite greedy but they don't care about flesh so you won't die. The final one is the Forest of Giants. It's called that because the trees are hundreds and thousands of feet tall. The guardian of that forest is a fire demon named Hiei and he doesn't like humans. He kills anyone that crosses him."
Sapphire asked, "How are we supposed to get passed him?"
Their grandfather explained, "There's an old legend, and I think it's true. Many don't believe it at all and think it's a lie. It's said Hiei, the guardian of the Forest of Giants, has a sister. She's an ice demon that lives deep within the mountains."
"I thought you said Hiei was a fire demon before," Amethyst said.
"Yeah," Sapphire added, "how can he have an ice demon for a sister?"
"Demons rarely mix blood," he continued, "his parents were quite the scandals in the demon teritory, which is why Hiei and his sister don't acknowledge each other at all. If not they could be killed for being 'mixed bloods.' Even mentioning her name around him will soften him and he probably won't kill you. Probably."
Amethyst said, "But that Yusuke guy, he's part human even now, right? They don't care that he's mixed?"
He said, "No, demons have been mixing with humans for centuries; with each other, not so much. It's said that Hiei's sister doesn't even know who he is, just that she has a twin brother."
"They're twins?" Sapphire asked.
"Like us!" Amethyst said.
He asked, "Wouldn't you be upset if you never got to see your sister again?"
They looked at each other sadly. Sapphire asked, "What's her name?"
"Yukina," he answered, "are you sure you two want to do this?" They both agreed without hesitating.
