The Next Morning.
Karan woke up before the sun had rised. Kaien was in the bed next to hers snoring, completely oblivious to the world around him. Karan quickly got up and jumped to her brother's bed.
"Kai." Karan whispered shaking her brother softly but Kaien was a heavy sleeper and didn't stir.
"Kaien." Karan said louder but Kaien just let out a snore.
"Kaien!" Karan said pushing her brother off his bed.
"Wha!" Kaien said as he shouted surprised.
"Oh good you're up." Karan said.
"Karan!" Kaien yelled angrily.
"We have to get ready for training." Karan reminded him.
"Oh!" he said jumping to his feet. He grabbed his clothes and headed to the bathroom but his sister beat him to it. "hey!"
"You should have woken up earlier." Karan said as she closed the door.
"UH!" He groaned.
They quickly got dressed and grabbed their gear before heading to the kitchen. They each grabbed an apple before heading down to the training floor.
"Want to spar?" Kaien said.
"Need to warm up first. Run through some katas and maybe some meditation." I said.
"Uh how can you sit still for so long." Kaien said.
"That's part of why it's such a good exercise. It takes a lot of physical and mental energy to do it right." Karan said.
"Your sister's right Kaien. I'm glad you two have been keeping up with your training regimen." Itachi said.
"We had a lot of time." Kaien said.
"Have you two been practicing anything new?" Itachi asked. The double meaning was lost on Kaien but Karan caught on pretty fast.
"A bit but I don't think we've gotten better." Karan said and Kaien gave her a look. Karan gave him a look back and he finally caught on.
"It's still hard to keep up with how much chakra it takes." Kaien said.
"That gets better with practice and by using it more. I imagine you have it easier since you have better chakra control?" Itachi asked Karan.
"I don't get as tired as Kai but it's still hard to keep up." Karan said.
"Can you show me? Spar while using your Sharingan." Itachi said.
"Uh okay." Karan said getting up.
"Anything goes?" Kaien said.
"You sure about that?" Karan said with a smirk.
"On second thought no shuriken, those things hurt." Kaien said.
"Okay." She said.
"Whenever you're ready." Itachi said. Both twins closed their eyes and opened them to reveal their Sharingan.
'Both of them have two tomoe on their eyes. They've advanced faster than I expected they would.' Itachi thought.
A second after they opened their eyes they moved. Itachi had seen them spar before but with the Sharingan they moved faster. They could predict each other's movements and act accordingly. If one threw a punching the other would dodge or block. Eventually they'd catch on and go on the offensive. Kaien threw a punch Karan would deflect and kick Kaien to the side. She'd speed to try and land another hit but Kaien used a substitution at the last minute and snuck up on her. She copied his substitution.
"Fire Style: Giant Fireball Jutsu" She shouted before shooting a fireball at him.
"Crap." Kaien shouted jumping out of the way just in time. "That's how you want to play it, fine." He said before making hand signs. "Fire style: Phoenix flower jutsu!"
Karan quickly made some hand signs and slammed her hands on the floor.
"Earth Style: Mudwall jutsu." Karan called out. A giant wall rose from the ground and blocked the attack. At least it appeared like it did. The wall started cracking before the force of the blast blew Karan back but she quickly landed on her feet just in time to see the shuriken lying towards her.
Karan quickly got a kunai and deflected each of them with ease just as she was getting ready for a counter attack someone started clapping.
Karan and Kaien quickly turned to see who was clapping and froze when they saw Madara standing there.
"Very impressive. You both unlocked your Sharingan." Madara said.
The twins quickly deactivated their Sharingans and slowly moved to stand close to each other.
"Their training has paid off." Itachi said. "Whatever changes you made to their regimen has gotten you the results you wanted."
"It's a lot more developed than I anticipated. Activate it." He ordered.
"No." Kaien said defiantly.
"Kai." Karan chastised.
"No? Fine." Madara said before disappearing and then appearing in front of Kaien and kicking him back.
"KAI!" Karan yelled before Madara punched her knocking her down.
"Fire Style: Giant Fireball jutsu!" Kaien fired but it just phased through him. Madara disappeared before hitting Kaien again. "Uh." He grunted as he fell next to his sister.
Karan sat up with a grunt and moved next to her brother.
"You really think you stand a chance against me you pathetic brats?" Madara growled.
"Get away from my brother." Karan said glaring at Madara with her Sharingan activated.
"You're… never going to… hurt us again." Kaien said taking his sister's hand and taking out the gem from before.
"Where did you get that?!" Madara shouted before the gem started glowing brighter and brighter before they disappeared.
"Did they teleport?" Itachi said. "All traces of their Chakra are completely gone."
"No, this is much worse." Madara said.
