Bruce opened the door for Percy, to the training room. Both of them were now dressed in clothes that were suitable for the gym.

Percy was rather impressed, but nothing beat Camp. Though, her uncle had a rock wall, which made her smile.

The rock wall, while it didn't spit lava, took up an entire wall, and the pieces gradually got smaller and further apart, the higher up they were.

Bruce caught her looking at the rock wall, with a small smile on her face, "would you like to go on it?" he asked her.

Percy looked at him, and grinned. Then she ran to the wall, and started scaling it.

Bruce watched with rapt attention as his niece climbed the wall with speed and grace that spoke of years of training and experience. Far beyond his boys, and himself.

"You climb?" Bruce asked.

"No, the camp I went to had a rock wall. It would be a competition to see who could get up, and down, the fastest, without getting hurt," Percy said, with a chuckle.

"Without getting hurt?" Bruce asked.

"Yeah. It was a tricky walk, but it was fun," Percy said, waving her hand.

"Seems like it," Bruce said. He felt relieved to see her looking relaxed.

She sat on the ledge and looked down, and smirked.

Bruce raised an eyebrow, recognizing the mischief in the sea green eyes looking at him.

Percy smirked and jumped off of the ledge. She tucked and rolled, as she met the ground. She ended in a standing position, looking at her uncle.

Bruce sighed. He'd be scolding her, if he wasn't already used to his boys doing that.

Percy caught the reaction and laughed, "my cousins do that a lot?"

"All the time," Bruce said.

"It's the quickest way down," Percy said, with a shrug.

"Damian said the same thing," Bruce said.

"Work smarter, not harder," Percy said, with a nod.

Bruce laughed, "anyway. Damian mentioned you have some form of training," he said, changing the topic.

"So does he, and the rest of you," Percy said, raising an eyebrow.

"Yes, so with that in mind. Want to spar?" Bruce asked.

Percy smirked, "sure."

Bruce led her to the mat, and the two began to stretch a bit.

"Do you have conversations during your sparing matches?" Percy asked, as they stretch.

"Depends on the match," Bruce said.

Percy nodded, "alright. Let's get started." Percy was jumping on the balls of her feet, loosening up her joints.

Bruce nodded, and the match began. 

—————
Tim and Damian both got walked in the front door, followed by Alfred.

"Master Bruce and Miss Percy are in the training room, but I'd suggest doing your homework first," Alfred said.

Tim and Damian both shared a look, and ran off with their book bags, to the training room.

They were rather taken back by the amount of sweat covering Bruce and Percy.

Bruce looked like he went for a swim, and Percy only looked like she ran a mile.

Both were bruised, but Bruce was clearly not winning much.

"Boys," Bruce greeted, before focusing on the match again.

"Welcome back from school," Percy said smiling at them. Percy then looked at her uncle and jumped at him. She wrapped her legs around his neck and swung her body. She got off of him, as he got reacquainted with the mat, and stood up to properly greet her cousins.

"How was school?" she asked them, ignoring the gaping look on Tim, and the wide eyes on Damian.

"It was good, and that was awesome," Damian said.

Tim nodded his head.

Percy smiled, "thanks. But you two have homework, right?"

"She's right. Go do you're homework, then you can come back," Bruce said, looking at his sons.

Both left the room, with much hesitation.

Bruce looked at Percy, "you are good."

"Thanks. It was fun," Percy said.

"I need to get things ready for my business, though. It needs to be ready for tomorrow," Bruce said.

"Sounds fair. We've been in here for a while," Percy said.

"See you at dinner, Perce," Bruce said, giving a small smile to his niece.

Percy left quickly after Bruce was gone. She went to the kitchen and grabbed a couple doughnuts for Blackjack, who had been watching them train the entire time.

She ran up to her room and opened her balcony doors, that had an impatient Pegasus waiting for her.

"Sorry, bud. I didn't mean to make you wait that long," Percy said.

"It's fine, boss. You did rather difficult things today. I'm just glad you're uncle was able to help you," Blackjack said.

Percy smiled, "yeah. He did help."

"Can I stay tonight? Since you're going to call me again tomorrow?" Blackjack asked.

"Sure, bud. Just don't get seen, and do not leave the property," Percy said.

"You got it, boss," Blackjack said.

Percy went back inside and closed the balcony doors.

She grabbed a water bottle, then made her way back to the training room.

She went over to the sword rack, and looked over them. She went over and looked for a sword that was balanced in her hand.

Once she found one, she took it and walked over to the dummies. The ones used for swords, and blades and such, not the punching bags on the other side of the room.

She did a few warm up moves, then the moves started to get faster, more intricate, and dangerous.

This was how Tim and Damian found her.

Damian watched when he got to the training room. Tim looked at Damian confused, when he got there. But his eyes widened when he saw what Percy was doing.

"She's good," Damian said, quietly, not wanting to disturb her.

"You're impressed!?" Tim said, not keeping quiet.

Percy stopped and looked at them, "hey, guys."

"Hey, Percy," Damian said, glaring at Tim.

"Hey. Done with your homework?" Percy asked, raising an eyebrow.

"Of course," Tim said, smiling at his cousin.

"Good to hear. I always hated my homework, didn't do it most of the time," Percy said.

"Really?" Tim asked.

"Yeah. I'm dyslexic. So reading it was extremely difficult when the letters and numbers would fly off the page around my head," Percy said, shrugging her shoulders.

"At least you're graduated now," Damian said, his eyes a little narrowed.

Percy recognized the look, and chuckled a little, "true."

"Wanna spar?" Damian asked.

"You know how to wield a blade," Percy said, nodding over to the sword rack.

Damian grinned and grabbed his katana.

Percy waited for him on the mat. Tim decided to climb the rock wall, and watch at the top of it.

Damian warmed up and stretched a bit, which gave Tim time to get to the top.

"Ready?" Percy asked, still swinging her sword around in figure eights, swapping from arm to arm.

Damian nodded at her.

"Tim, call it," Percy shouted at him.

"How are you ending it?" Tim shouted back.

"First to yield," Percy answered.

"Got it. Ready," Tim said.

Both got into position.

"Begin!" Tim shouted, holding his phone out and recording the whole thing.
—————
Bruce and Jason received a message, with a live feed to a sword fight in the mansion.

Bruce stopped his paperwork and turned on the video. He was rather surprised to see Damian and Percy sparing.

Percy didn't even look tired from his sparing match with her, and he almost fell asleep in the shower.

Jason was at his club when he got the message. He was in his office, so he was all willing to pull his phone out and check it out.
He rolled his eyes when he saw who it was from. But the link was eye catching. It mentioned sword fighting, and that was enough to make Jason click on it.

His eyes widened when he saw Demon sparing his cousin, and she was holding back a bit.

He was able to pinpoint when her fighting shifted. She was going off of instinct part way through the match. And she was gaining the upper hand.

She pulled a move that made Damian's katana go flying from his hand. She held the tip of her sword at his throat, "yield?"

Damian kicked her stomach and somersaulted over to his katana. He picked it up his stray katana.

He also grabbed his other katana. Percy laughed, and grabbed another dagger.

Everyone watching was able to see they were having fun.

The match continued.

The sparring continued, and before long, Percy was at Damian's back. Her sword was at the front of his neck, and the dagger was up against his lower back.

"Do you yield?" Percy asked, again.

Tim looked at the pair with wide eyes, as did the two watching the video feed.

"I yield," Damian said, with gritted teeth.

Percy dropped the weapons back to her side, "that was fun."

Both of them were covered in small scraps and cuts. But neither noticed that much.

"Who trained you?" Damian asked.

Percy smiled, but it was very strained, "I've been learning since I was twelve."

Damian stopped asking questions. He saw her mood shift, "well, it was fun. And I want a rematch."

"Maybe later. I'm going to go shower now," she said. Then she left the room.

Damian looked at Tim, who had stopped recording, "send that to me."

"Sure," Tim said.

Bruce looked at his phone with wide eyes. The stream was finished, but it was impressive.

Jason whistled, "she knows something about surviving."
