Yuki looked up at the strange castle before her. She couldn't understand why the castle was so strange. What purpose anyone would have for such a strange structure was beyond her understanding. It looked like most of the castle was inaccessible. Parts of the castle were sideways for the love of Kingdom Hearts!

Yuki sighed walking up to the front doors of Castle Oblivion. She pushed the doors open taking a deep breath before walking into the pure white halls Yuki hadn't seen for months.

Castle Oblivion was usually left unattended when the Heartless and Nobodies weren't using it. The castle was confusing enough that any intruder wouldn't be able to find anything useful. Not to mention the location of the world that was nearing impossible to just stumble across. Sometimes a Heartless or Nobody would be sent to look over the castle, look for anything important, then head straight back to their own castle. It wasn't a common set of orders, usually, it came with the order of finding some report. But today Yuki was given the order to go to Castle Oblivion. Go to the castle and find the organization 13 imposter who had been sighted wandering the halls.

Yuki wandered through the halls, looking into rooms as she passed. The place was surprisingly empty. Not even a Dusk or a Shadow was seen. Perhaps the imposter had killed them all. That would explain where they had vanished to. But it wouldn't help in finding the imposter in the huge castle.

On the top floor, Yuki stopped to rest. She was in the room the Nobodies had used as their base. The room Marluxia had shown Yuki the intruders from. The crystal orb they had used to watch the intruders sat in the middle of the room, now filled with a dark smoke. Everything else in the room looked just like the rest of the castle. Pure white. It wasn't very impressive. It was everything Yuki was used to but at the same time, it felt foreign, like Yuki didn't belong there.

Yuki frowned looking around the room. It would take too long for her to search the rest of the castle. There was still the twelve lower floors to search and all of the side rooms that Yuki wasn't even sure she'd be able to find. There was also the chance that she had already missed the imposter. This castle had endless escape routes. The imposter could have easily already left. It wasn't as if Yuki had a way to see where he was in the castle without seeing him face to face.

As soon as the thought came to mind Yuki turned to look at the orb. Maybe she did. Yuki stood and made her way to the orb. She placed her hand against it. The glass was cool to the touch like it had been left out in the cold rather than in the castle. The smoke inside the castle immediately began shifting around. Yuki smiled softly looking at the orb. She closed her eyes and brought to mind an image of the imposter. His silver hair and the blindfold he wore. It was easy to bring an image to mind though she had only seen him once.

Yuki opened her eyes and looked at the orb. The smoke had formed an image now. The imposter was clearly seen. He was sitting on the steps to one of the floors with his hood up. Even so, Yuki had no doubt in her mind it was him. He was talking to someone, but who that someone was Yuki had no idea. She couldn't hear anything either.

Yuki frowned. Though she knew he was still in the castle she had no idea what floor. All the floors looked the same. By the time she found which floor he was on, he could have very well moved again. It would take a lot of effort to discover his location.

"What floor?" Yuki whispered in question, pulling her hand away. She turned her back on the orb and began to pace. Her mind came up with idea after idea, each one getting more pointless than the one before. It was turning out to be far more difficult than Yuki originally thought.

The door behind Yuki suddenly opened. She turned calling Heartless Keeper to her hand. In the doorway was the imposter and another dressed the same way. The other was female and her hood was up.

"Yuki?" The female asked taking a step forward. The imposter put his hand out to stop the other from coming any closer. Yuki already knew who the other was. Xion. But why was she with the imposter?

"You're the one who visits Naminé all time, aren't you?" The imposter asked, drawing attention off of Xion and on to himself. Why he was asking that specific question was lost on Yuki. Yuki didn't answer, she instead chose to glare at the boy. He stepped forward drawing closer. Yuki didn't react to his movement. "Why are you here?" The imposter asked.

"I'm supposed to get rid of you," Yuki replied softly. Her eyes were looking between the imposter and Xion now. Xion was looking down at her feet, avoiding Yuki's gaze. The imposter was standing his ground. Though Yuki couldn't see his eyes she could almost feel his glare. "The first time we met you told the man in red Xion had a name." Yuki said. The imposter looked over his shoulder to Xion then back to Yuki.

"What of it?" He asked. Yuki shrugged.

"I just remembered that. He called her a puppet and you said her name was Xion." Yuki glanced back at Xion once again. "And yes, I visit Nami quite frequently. But what does that matter? I don't stop her from working on whoever that boy is."

"Naminé said you were important. But refused to elaborate on how." The imposter answered. In his hand the strange blade he used suddenly appeared. "DiZ said you needed to be stopped, or you would kill him." He raised his blade and stood at the ready. Yuki sighed calling forth her other keyblade.

The imposter darted forward almost without warning. Yuki barely noticed him tense just before his movement. Yuki brought up her key to block his blow from the side. He jumped back from contact while Yuki was pushed back. He didn't waste a moment before attacking again, this time with magic. A blast of fire shot towards Yuki. Yuki raised Twilight Keeper and shot an orb of light at the oncoming fireball. They collided mid-air in an explosion. The imposter took a step back in shock, looking from Yuki to where the explosion had been in confusion.

"Heartless are creatures of darkness, yet you use the light." He said, mostly to himself. Yuki watched him cautiously. He didn't look like he was going to attack again. He was too much in shock. That shock made Yuki wonder, was he a user of light? Was that why he was so confused with Yuki's use of light? Yuki frowned, her eyes turning yellow. His heart wasn't light. But it wasn't really dark. It was both swirling together creating the appearance of the sky at dawn.

"Let's get out of here," Xion said. She tugged on the imposter's arm desperately. He glanced at her and nodded. He opened a dark corridor, allowing Xion to go through first before following himself. Yuki watched in silence, deciding not to follow them through. Once the dark corridor closed Yuki banished her two keyblades. She let out a heavy breath, rubbing her temple. The imposter was gone from Castle Oblivion, but not gone for good.

Yuki summoned a dark corridor to take her to the entrance hall. She saw no use in wandering the halls once again.

In the entrance hall, Yuki was greeted with a surprise. Axel was crouched down beside Roxas. Roxas looked to be unconscious.

"Axel," Yuki said. The redhead looked up at her in shock. "What happened?" She asked. She walked over and crouched down beside Roxas.

"We walked in the doors and he collapsed," Axel replied. Yuki frowned, reaching out to check his forehead. It wasn't warm at all.

"Must be something in the castle. We should get him out of here." She said standing up. Axel nodded, standing up himself while supporting Roxas. Yuki opened a dark corridor and allowed Axel through before following herself. The corridor came out in Twilight Town. Axel placed Roxas down on the ground and watched him nervously from the wall. Yuki took a seat on a crate not far away.

"So where have you been Snowy? You haven't been to the clock tower in a few days, I was beginning to think you flew the coop." Axel asked. Yuki could tell he was trying to get his mind off of Roxas. Just ask anything to keep himself from worrying about the blonde Nobody.

"Here, mostly," Yuki replied with a shrug. Axel raised his eyebrows at her.

"That's not what I meant and you know it." He said. Yuki looked at the ground to avoid his gaze. Her eyes landed on Roxas. He looked almost lifeless, his chest barely rising and falling with each breath.

"I've been trying to sort out the thoughts in my head," Yuki said. Axel looked at her with a soft expression. He looked away from Yuki, looking back to Roxas.

"Same sort of thing Roxas sees?" He asked. Yuki shrugged.

"Maybe, I haven't really talked to him about it."

"So it's the sort of things you can't talk to your friends about," Axel said. He almost sounded hurt, but Yuki knew otherwise. Axel was the most insistent that they didn't have hearts.

"It's the sort of things I'm scared to talk to my friends about," Yuki replied. The idea of having to tell any of those who came to the clock tower the thoughts she had been struggling with terrified her. She was scared to think maybe she was on the wrong side. Maybe she should be fighting against the organizations alongside the imposter. Maybe she should be with Naminé helping save the hero. Maybe she belonged with the friends she barely remembered and not the ones she had made.

Axel nodded like he understood. He didn't say anything more. The two sat silently waiting for Roxas to wake up.

Roxas woke a few moments later. He shot up quickly without warning. Yuki jumped at his sudden movement.

"Riku!" Roxas said. Yuki looked at Roxas in shock. Where had he heard that name?

"You alright there?" Axel asked, ignoring what Roxas had just said. Roxas looked at him putting a hand against his head.

"What happened to me?" Roxas asked confused.

"You collapsed as soon as you got in the castle. Don't you remember?" Axel asked he glanced at Yuki concerned. Yuki shrugged calmly. Axel might not be used to it, but Yuki knew that was usually how it worked.

"I only remember going in," Roxas said standing up. He looked at Axel with a frown.

"Just take it easy for now." Axel said in warning. Roxas shook his head stubbornly.

"I'm fine, we need to go back to Castle Oblivion." He insisted. Axel opened his mouth to argue but was cut off by Yuki.

"There's nothing there," Yuki said. Roxas looked over at her surprised. It was clear he hadn't noticed her until now. Yuki didn't let that affect her. "I just went through the castle, there's nothing there."

"But, the imposter was sighted there." Roxas insisted.

"Gone, he ran away after fighting with me." Yuki said simply. Axel nodded towards Yuki. She smiled at him softly.

"There's no need to push yourself." Axel said. He glanced up. Yuki watched him tense before turning to look over her shoulder. Behind her were two figures. Xion and the imposter.

"Xion?" Roxas asked. Xion lowered her head and turned away. She opened a dark corridor and went through it. Roxas darted forward, trying to reach her. "Xion, wait!" He called. The imposter stepped forward blocking Roxas' way. Behind him, the dark corridor closed.

"Roxas," Yuki said in warning. She knew the imposter had held back against her earlier. She doubted he would hold back again. Roxas ignored her.

"Get out of the way." Roxas ordered. The imposter turned away and ran off. Roxas clenched his fist before taking off after him.

"Roxas, wait!" Axel called before following after Roxas. Yuki sighed heavily but got up and followed the Nobodies into the underground of the town.

In the underground, the imposter ran in circles as far as Yuki could tell. If he got cornered he would just teleport out of the way. And no matter how many times he was hit by Roxas or Axel he never slowed. Yuki hung back, not putting as much effort in as she could. She wasn't in the mood for a wild goose chase.

After Roxas and Axel had cornered him in the tunnels once again Yuki approached them from behind. The imposter again didn't speak as he opened a dark corridor and fled. Yuki frowned, he was pretty talkative when it was just her he was against. Did he not want to talk in front Roxas or Axel?

"The imposter was already chased out of Oblivion, why would he come here?" Axel asked.

"Maybe his base is somewhere close," Yuki suggested, thinking of the manor. She was fairly certain that's where the imposter was hiding out most of the time. Axel seemed to consider it a moment but didn't agree or disagree.

"Xion," Roxas said sadly. Axel looked at him in confusion.

"No way that was Xion." Axel said.

"The one who ran away first was Xion." Roxas insisted. Yuki frowned.

"Xion was with him in Castle Oblivion." She said gaining both of the boys' attention. "Did she leave the organization or something?" Yuki asked. Axel nodded slowly.

"Forgot you stopped showing up around the same time she did." He said. Yuki frowned.

"What did I miss?" She asked.

*<3*

Yuki looked down at the ground in shock. Xion had just left and Roxas and Axel had been looking for her. X and Y had also been visiting the clock tower less and less.

"I'm sorry you guys." Yuki said.

"It's fine Snowy." Axel said with a hand wave.

"Yeah, you'll come around more often. Right?" Roxas asked hopefully. Yuki smiled at him softly.

"I'll try. And I'll keep an eye out for Xion too." She said. She did hope to come by more often, but her mind kept replaying one thing over and over. Roxas saying Riku's name. Who the hell was he?

*<3*

Day 297- Thinking like me,
I saw the imposter again. I had to get him out of Castle Oblivion. Xion was with him. According to Axel and Roxas, she ran away a while ago. I haven't been around to hear what's happening so I was a little behind.
Roxas passed out. When he woke up he said Riku. It makes me wonder. With Xion running away and Roxas saying that name, are they thinking like me?
