A big headache

Both siblings watched the sunset, sitting upon the bank of their favorite pond.

"Little squirt, now that you have some control of your chakra, I will show you one of the easiest and most useful shinobi Jutsus."

Kaname's view of Ryuichi was instantly blocked by a wall of smoke, which quickly dispersed.

"This Jutsu is called <Henge> (Transformation Jutsu), as you can see, I transformed my body and clothes to look like Minato-san's, just perform these hand seals and try to visualize how you want to look," Ryuichi explained.

"Wow, it is amazing, Aniki! I can use this for so many pranks!" Kaname replied, plans already forming inside her mind. She repeated the same hand seals, put some chakra into it, and thought of her brother. From a smoke cloud, arrived disfigured imitation of Ryuichi, "How do I loo- gods damn it!"

"Hahaha, good for the first try Little Squirt, you will have 4 years in the academy to perfect this Jutsu with 2 other basic ones. To release this Jutsu, use the tiger seal and say <Kai>, seeing your hands don't have any fingers, you can wait 10 minutes for transformation to wear off, I will help you this time." He chakra powered his finger and flicked his not exact doppelganger's forehead.

"Ouch! You meanie." Kaname cried out, back in her own body, holding her hands on the red spot in the middle of her forehead.

"One more thing you're still young, Little Squirt, don't overuse this jutsu, it may deplete your chakra reserves, and make you lose your consciousness. Tomorrow after training with my team, I will try to show you some basic Uchiha's taijutsu skills."

"Yay, you're the best aniki!"

Just a second after the siblings entered their home, Kaname heard her mom's voice coming from the kitchen "Go take a bath, Little Butterfly, it's getting late. Don't forget to brush your teeth!"

"Yes, I'm going," Kaname shouted out. 'A mirror, let's try again!'

"<Henge>" she whispered, after 2 other failures Kaname heard someone knock on the bathroom doors.

"Princess, are you alright? You spent 20 minutes in there."

She couldn't exactly say everything is ok, it would be weird to answer this question in Minato-san's voice 'Aah, I'm going to get in so much trouble... kai, Kai' Kaname thought. She was still seeing blonde's face in the mirror 'Right concentration, let's try... now, KAI!' with a small *Poff* she was back in her own body, "I'm sorry mommy, water was so warm I slept a little bit." she said a white lie, faking her yawning.

"It seems you got tired, finish your bath, and march to bed." Kaname heard her mother's worried voice right outside the doors.

'Phew, a big chewing out averted.'

"Goodnight Mommy, Goodnight Aniki!" said the little mayhem giving them both kisses on their cheeks. In the next 50 minutes, Kaname's bedroom was filled with numerous smoke clouds and *Poff* sounds.

'Good, thirteenth try, and at last, I have got fingers to work with!'

"<Kai>" she whispered, 'Let's try to henge into my brother.' she thought.

"<Henge>" from a far smaller smoke cloud than normal, came out her own body 'Ahh, I forgot about that.' She landed headfirst into her own bed unconscious.

"Princess, are you alright? Its almost noon already, you never overslept breakfast." through a massive headache, she heard her mother's voice.

"Little Butterfly, what's wrong!?" She felt her worried mother's hand on her forehead. "It seems you got a fever. Stay in bed, I will prepare something warm to eat for you.".

Kaname was not sure how much time elapsed before a flick to her forehead woke her up. "Little Squirt, if I remember right, I said NOT to overuse this Jutsu. How many times did you try it?"

"Guuu, leave me alone, baka-aniki… Fourteen or Fifteen times, if you need to know." Kaname replied, shily scratching her head.

"Wow, not bad, First time I lost my consciousness after the seventh attempt. Don't worry, every good shinobi needs to know what are his or her limits, with training and age your chakra reserves will increase. At the moment, your chakra levels are low-level Genin, but you need to work on your control."

"Guh, not the time Aniki." the little girl whispered.

"Yeah, you should stay in bed today and rest Little Squirt. Let's postpone your taijutsu lesson for tomorrow.".

"But I want to learn-" *Flick* "Ouch!"

"Rest or I won't get you a gift," Ryuichi replied with a knowing smile.

" ...Okay. I'm sorry, Aniki." with a small voice his sister said.

"Haha, don't worry, Little Squirt, everyone went through the same. Sleep now, I will wake you up for dinner." With a small smile Kaname turned to the side, she found a comfortable cold spot in her bed and took her brother's hand into hers, she never so easily drifted away into a land of dreams.
