Chapter 1: The Fox Siblings

Deep in the forest, there is a cave. Inside the cave as you go deeper and further below, there is a entrance. This secret place, hidden in a cave surrounded by the forest, is controlled by a man named Dr. Eggman. The evil villain laughed as he accomplished capturing something, or rather someone.

"I have finally captured the nine tail fox! And once I drained the fox's powers, I can wish for anything! And I didn't even have to do any damage to her. She decided to wear herself out from the moment I put her in the glass capsule." Dr. Eggman said as he looked at a giant round glass capsule, inside it was a young female fox with nine tails. The nine tail fox girl panted softly, exhausted that she used most of her strength to try and break free out of the capsule.

"Try all you want, but that capsule is indestructible!" Dr. Eggman said as he leaned close to meet the fox girl's eyes. She growled then scratched the glass making Dr. Eggman startled as he stepped back.

"You little brat!" He growled about to hit the glass when the alarm started blaring. Dr. Eggman went towards the giant computer screen to see what was wrong and the fox girl scoffed.
I was so close to getting him... No matter. Now... There has to be a way out of this... She thought as she looked around. As she was about to grab ahold of her flower pin the fox girl suddenly heard an explosion. She turned to see what was going on but there was a huge cloud of smoke. Suddenly a bright blue light came towards her but it broke the capsule. She started coughing from the cloud of smoke then the fox girl gasped when someone lifted her up and held her bridal style. In a blink of an eye whoever was carrying the fox girl went out of the room and started running down the halls. The girl looked up to see a blue hedgehog was carrying her and started running.

"Are you okay? Did Eggman hurt you?" The blue hedgehog asked then the girl shook her head.
"Who are you?" She asked looking at the blue hedgehog.
"Me? The name's Sonic; Sonic the hedgehog." He said then when Sonic turned down the hall they passed a room and the fox girl gasped softly as she saw a black fox with five tails inside a giant tube that was filled with water.

"KIRA!" she shouted as she started moving.

"Hey! Stop squirming I'm gonna drop you!" Sonic said as he was still running but the fox girl still kept squirming.
"Let me go! I have to save Kira!"
"Who?! Who's Kira?!" Sonic asked as he slowed down a bit but the girl kept moving around.
"Let... Me... GO!" She struggled then with no hesitation, she bit Sonic's arm making the blue hedgehog shout in pain but he finally dropped the fox girl. With quick recovery, she jumped over Sonic and started running to find the room the black fox, Kira, was in.

"She bit me... She bit my arm..." Sonic said as he looked to see if he was bleeding, luckily there wasn't any blood. When he looked in the direction she ran he saw her attacking a bunch of robots with a floral looking scythe.

"Where did she get that scythe...?" Sonic asked himself, amazed at how swiftly her attacks were. The fox girl finally found the room, destroyed the two robots that were in there then looked at the tube that Kira was in. She swung her scythe and broke it. Water poured out then she caught Kira and held him.
"Kira...? Kira, speak to me!" She begged then Kira didn't move. The fox girl was about to cry when Kira started coughing.

"Kira...?"

"Ku...ro..."

"Oh my gosh...! I thought I lost you...!" The fox girl, Kuro, whimpered as she sobbed. Kira smiled weakly and pressed his forehead against Kuro's cheek. Suddenly the two foxes heard a screech down the hall and saw Sonic in front of the enterance.
"Hey! You found Kira?! Great... Hey, so I may have accidentally activated the base's self-destruction button when I was fighting some robots, so we gotta leave... Right now."

"WHAT?!" Both foxes said then Kuro helped Kira up.

"Take Kira." Kuro said then Sonic nodded and piggybacked Kira. As Kuro and Sonic ran out of the secret base and out of the cave, they saw something flashing in the cave then smoke slowly came out of the cave. Both Sonic and Kuro were panting then the blue hedgehog placed Kira down.

"Thank you for saving us, Sonic." Kira thanked bowing his head then Sonic tilted his head to the side.
"Have we met? He asked.

"No. But I've heard about you from the Royal Zone."

"Royal Zone?"

"It's surrounded by Turquoise Hill Zone." Kira explained then Sonic scratched the back of his head.
"Aww shucks I didn't know I was so well heard." The blue hedgehog said bashfully then Kuro walked towards Kira.
"You know, you don't have to thank him Kira. He's not the one who saved you."

"What are you talking about? He saved us both, Kuro!"

"Oh yeah? I could've saved us both if blue boy didn't interfere!"

"That reminds me... Why did you bit me?!"

"Because you wouldn't listen and you were asking stupid questions."

"All I asked was 'Who's Kira?'! If you told me you had to save your boyfriend, I would've helped!" Sonic said then both Kuro and Kira gasped. Sonic both looked at the foxes oddly, as if what he said might've been wrong. And his hunch was correct when he heard Kira chuckling.
"That's the first time someone thought of me as my older sister's boyfriend."

"'Older sister'?! So wait... You're not...?" Sonic stuttered then Kira shook his head.
"No, no, no. Of course not. Allow me to introduce ourselves; I am Kira Yukimura, the youngest. And this is my older sister, Kuro Yukimura." The black fox said then Kuro huffed turning her head away.

"But you... And she... And, uhhh..." Sonic stuttered then Kuro shook her head, disappointed in the blue hedgehog.
"Bad move, blue boy."

"Hey! You didn't say anything! So in actuality it's your fault!" Sonic said then in the blink of an eye, Kuro was gone but she appeared in front of Sonic and she hit him with the dull side of her scythe. Sonic tried to get up but Kuro point the sharp edge towards his neck.
"Give me a good reason why I shouldn't end your life right here right now..."

"Kuro!" Kira shouted his sister's name then she still kept her eyes on Sonic.

"Don't do it, Kuro! I know you better than anyone and you wouldn't go far as to kill someone if they pissed you off! Sure you'll say hurtful things, but come on... Don't do this... You're my older sister... I look up to you..." Kira said then Kuro remained silent. After a few seconds her scythe turned back into her flower hair pin. She placed it in her hair then gave Sonic a cold look.
"You're lucky my brother is here..." She said then she dashed off and vanished. Kira came towards Sonic, helped him up and dusted him.
"I apologize for my sister's behavior... I do hope you find it in your heart to forgive her. I will send a gift regarding my thanks and apologies." Kira said as he ran off leaving the blue hedgehog alone.

"Man... What the heck just happened...?" He muttered to himself.
