Shikokou, Kyukai

Yuki and Kaori slept with Sonic and Tails for the night, much to Yuki's frustration. When they woke up Sonic told Tails about last night.

"So are they on our side now?"
"Do you think they should tag along?"
"I don't see why not!"
Sonic wrapped his arms around the two new faces. "Okay. Welcome aboard!"
"Okay, let's get started on training!"
"You mean right now? Shouldn't we wait a bit?" Kaori asked.
"I can't wait for anything." Sonic replied.
"Well, are we supposed to train in here? I think it'd be too crowded."
Tails walked to the door. "No, there's an area out in the back I made specifically for training. I think you'll like it, check it out!"
Sonic followed Tails outside and then turned his head back over to Yuki and Kaori. "He's always making great stuff, so keep your hopes high!" Kaori followed after Sonic, then Yuki.

Tails revealed another building behind. Inside it was a large room with yellow walls and gray floor with a octagon pattern just like the lab. The space was entirely free to move around in and there was nothing but a touch screen at the back.
"Woah, this place is huge! Why didn't I ever notice it was behind the lab?"
"Um… is this it? I don't mean so sound rude but, this doesn't look very great." Kaori examined.
Tails walked up to the touch screen. "This is the exciting part right here. You can choose different obstacles, hazards and even enviroments. Aside from preparing for fights, this room was made to prepare us for anywhere we end up going."
"So, does that mean we can be ready for everything?"
"It'll help us, yes. But if we want any chance against the demon we're gonna have to train here every day. I want the three of you to spar each other at least once a day, but try to have about three matches."

Sonic walked up to the touch screen and examined the options.
Kaori felt the need to ask Tails a question. "Wait, what if something happens? Is this safe?"
"Yep. It's all polygons, so you can't get hurt."
Sonic ran back to the others. "I'm bored talking about this thing. Let's start training!"
Tails nodded. "Let's see which two go first. We won't pick any settings for now, I just want you to get into the hang of training with eachother. Now, I think I'll pair up…"
"…Me against him." Sonic butted in as he pointed at Yuki.
"Right, um…" Tails looked at Yuki and then Kaori. "Kaori, do you know his name yet?"
Kaori shook her head. "I don't know if we'll get to know his name, really."
Yuki sighed. "It's Yuki the Hedgehog."
"Right, Yuki! You're up against Sonic!"
"Why do I have to train with him?"
Sonic rubbed his index finger against his nose starching it with his usual cocky smirk. "I wanna see if you really are tough."
"You act too confident. You're probably not that great."
"Believe me, Sonic is the fastest and strongest in the world! He's been saving the world before I met him!"
"Alright, Yuji. Let's start training."
"But I don't wanna!"
"Okay, I'll train with him!"
"I can tell that'd be a boring fight."
"You're not very friendly, huh?"
"Leave yourself out of this!"
"Which one of you is—"
"Fine! Me and him!"
"It's about time!"

Sonic chuckled as he stretched his legs as usual, then came dashing toward Yuki. Yuki hit Sonic in the face three times, punched him stronger in the stomach, crouched down and sweeped his leg to trip him over. Sonic did a backflip and leapt over Yuki and kicked him in the back, then grabbed him and threw him against the wall. Yuki managed to leapt off the wall and shot a ki blast at him at point blank range. Sonic ran up the wall and out ran the continues ki blasts Yuki was shooting until Sonic leapt off and hit Yuki In the head with a homing attack.

Tails and Kaori watched.
"I can tell Sonic got stronger since I last saw him! He's also gotten even faster!"
"Yuki's also pretty strong. He must've done some sort of training when he was younger…"
Tails looked at his Miles Electric to look at the time and found out it was lunchtime. Tails called out to the two Hedgehogs sparring. "Hey, it's time to eat!"
Sonic, delighted to hear the news, shoved Yuki aside and ran out the door.

Everyone went back into the lab where Sonic, Kaori and Tails began stuffing themselves with food. On the table there was traditional food like Domburi, Tonkatsu, Katsu Curry, Udon Noodles and Miso Soup. Yuki was sitting in the corner watching them. "Do you guys always eat like this?"
Sonic tried to talk with all the rice in his mouth, but his attempt was futile. He had to swallow everything first. "You're lucky we haven't eaten your portion yet. You better eat it while it's here!"
Yuki lowered his head. "I'm not hungry anyway."
Everybody else kept eating rapidly. "Kao-Tan*, let's have an eating contest! Try to beat 20 serves!"
Kaori swallowed the masses of food in her mouth to talk to Yuki. "Hey Yuki, you still don't want yours? Cos I'll eat it!" She reached over to the centre of the table to grab Yuki's portion only to find it was gone. She looked over to see Sonic was slumping on his seat and let out a massive burp. "Hey! I wanted the rest!"
"It wasn't yours in the first place, anyway."

Sonic and Yuki walked out to resume training. "Now that I've eaten, I'll have heaps more energy! Yumi probably won't have much fight in him seeing as he didn't eat."
"It's Yuki, you idiot!"
"Great, now he's gonna start calling him names!"
Sonic looked over at Kaori. "He's a really friendly guy, huh Kao-Tan?"
Kaori looked confused. "He's the polar opposite. Why'd you say that?" She didn't seem to understand that Sonic was being sarcastic.
Tails taught this to Kaori. "What Sonic just said was what we call sarcasm. It's modern-day talk. Sarcasm is when one used irony to taunt somebody. In other words, when Sonic said Yuki was friendly he actually meant he was mean. Understand now?"
Kaori tried to get that through her head. "I understand… I guess. The future is really confusing, huh?"
Sonic got ready to spar with Yuki again. "Just cos this is training, doesn't mean you can take it lightly! I'm going to beat you up!"
"Heh. Let's just wait and see."

That night, after most of the people had gone to sleep Shadow was skating through Takashima looking for somebody in particular.

"No one defeats me and gets away with it alive! Emakarou, wherever you are I will find you and settle the score!"

Music - All Hail Shadow by Crush 40

Shadow skated through the jungle as fast as possible, going up and down, skating up loops and leaping from platform to platform when he came across a handful of demons. He chuckled to himself as he pulled out the green chaos emerald.

"CHAOS CONTROL!"

He teleported to the middle, beat up the ones around him, and then, the rest of the demons grabbed him in an attempt to crowd him and beat him up. Shadow had his arms in an X position, glowing red.

"CHAOS BLAST!"

A huge field of power surrounded him as all the demons were knocked out of the way. After this was done with, Shadow looked around to see that they were all defeated. He saw one of the demons trying to get up, so he delivered a sharp kick to the neck, finishing him off.

"Is that the best you got for me?" Shadow called out to Emakarou.

He continued his search, proceeding to the village, where more demons were awaiting him. He leapt off the cliff and as he was flying through the air, he used another chaos control to teleport behind the first one, delivered a powerful blow, teleported to the next to do the same, rinse and repeat for every other one there. Ready to fight off another wave of demons, he started his chaos boost, swerving in and out hitting every demon on the scene. He just missed the last one, which immediately after he passed, he stopped so shoulder him from behind.

"Heh. That was preschool work."

"Nice job, Shadow. Now I know at least you can put up a fight."
"Oh, so now you've decided to show yourself? I've been looking forward to this!"
"What are you so excited about? Don't you realise you're a shrimp compared to me?"
"That was because I was just going easy on you. I had no idea how strong you'd really be, so I got careless. Now that I know what I'm up against, I'll know to unleash my ultimate weapon."
Emakarou chuckled with delight. "I couldn't be more excited to see this."
Shadow skated forward madly when the demon backed up and began to fly away.
"What? You're running away?"
"No, I want to get the most entertainment out of you! You'll have to catch me!"
Shadow easily accomplished this feat with a chaos control. Then, he grabbed the demon, swung him around and tossed him away. Then he began charging red glowing energy into his hands – he was concentrating the chaos blast into his hands.

"Here's a little treat for you! CHAOS BLAST!"

He shot the energy that would usually be surrounding him out of his hands, aimed directly toward his opponent. Unfortunately for Shadow, the demon managed to catch it with his own hands. He threw it back so fast that Shadow had no time to dodge and was once again hit by his own attack. Before falling face first, Shadow back flipped off the ground fifty feet in the air and homed onto his foe with an aerial chaos boost, following him through Takashima while attempting to land a blow. The two moved at incredible pace from the village to the wilderness. Eventually Shadow lost patience.

"I'm sick of this!"

He used a chaos control and disappeared from Emakarou's sight. He tapped him on the shoulder, and as he turned around landed as many blows as he could while he had the chance. However, when he threw one more punch forward the demon caught it, punched him full force, kicked him sending him flying backwards and then fired a blast of energy. The two descended to the ground with Shadow all battered and bruised.

"Where's that ultimate weapon of yours you were talking about? I was hoping you could show me! Maybe it'll be able to inflict a little bit of damage!"
Shadow's frown turned to a smirk. "Heh heh. Oh, don't you worry." He raised his left hand in the air, charging something up.
"Woah… I sense his power raising by the second… this must be an incredible move!"
Shadow was charging it more and more until eventually it was ready. "Here's just a little going away present for you!"
"No way! This attack is too powerful to even block!"
"CHAOS…" Then, he shot a seven yellow spears of energy forward at the speed of light. "…SPEAR!"
Just when it looked like Shadow had finally turned the tide, the demon shot the same spears. The chaos spears collided with each other, leaving Shadow shocked.
"I… I don't believe this! He learnt the chaos spear too! AAAARRRGGH!"
After Shadow fired his seventh and last spear, Emakarou's last spear hit Shadow, leaving a harmful wound in his chest.

"That's all I got… And I can't use that attack again. I give up – you've beaten me."
"Normally, I'd just finish you off now and get you out of my way, but I'm in a good mood so, I'm going to make you an offer you can't refuse."
"What offer is that? I can't wait."
"Join forces with me and kill Emayuki and Sonic."
The second name listed caught Shadow's attention. "Wait, you know Sonic?"
"I've fought him three times, and none of those times he put up much of a fight."
That doesn't sound like Sonic… He's always beaten me… Then again, this guy is much stronger than I am…
"And who is this other guy?"
"He seems to be working with Sonic. To be honest, he's actually caught my interest. Now that I think about it, just kill Sonic and get Emayuki to join us."
"Do you honestly think I would join forces with the likes of you?"
"Listen! You can't beat me. If you continue to try to defeat me, I will kill you."
To be honest, I don't know if I can defeat this guy. It seems that no matter what I try, he'll still beat me. What do I do?
"I am still waiting! How long do you intend to keep me waiting for an answer? If you still refuse, I won't let you get away alive!"
Shadow aggressively stared at his fists looking as if he were going over the decision. Darn, where did I leave my chocolate? I could've sworn I had half of my chocolate left! But more importantly, should I really trust this guy? If he's asking me to kill Sonic, I don't know how I should think! I can't just keep going up against him like this… Uuuhh!
Shadow ultimately made up his mind. "Sorry. I refuse."
"But that's not fair! It was a really good offer!"

ALTERNATE ENDING

But more importantly, should I really trust this guy? If he's asking me to kill Sonic, I don't know how I should think! I can't just keep going up against him like this… Uuuhh!
Shadow ultimately made up his mind. "Fine. I'll do it!"
