Ren was sleeping peacefully until something jump on top of him taking his breath away a stunning him with a yell "Ren! wake up you sleepyhead, mom says that breakfast is ready"
After that he feel the weight off his body and he heard the sound of running footstep going in the direction of the kitchen.Ren wearily got up, he took off his pajamas, wore his clothes and went to the dining room where all his family where already waiting.
Just as Ren sat hi father stated"Now that everyone is here..."out of nowhere a rain of confetti stared falling on top of Ren and Sakura head"HAPPY BIRTHDAY!!!" yells Kizashi and Mebuki.
"Thank you mom and dad, and happy birthday to you too Sakura" after saying so Ren went to his mother and gave her a kiss on the cheek and did the same for his father and sister and after she too thanked her parents and wished a happy birthday to Ren.
Kizashi then with a fake moved expression said"I always get emotional on your birthday, I got cake in my eyes" before the family could react to the pun of the day Mebuki put the breakfast on the table and said "Kids ignore your father and start eating before it get cold"
Kizashi then turn to his wife "Dear you know that loving you is a piece of cake?" Mebuki ignore her husband and ask the kids "So guys what do you want to do today? Both your father and I took a day off from the mission so we can spend all day with you"
Sakura stood up and immediately replies"I wanna go to the park and play with Ino last time she said that the flower are about to bloom!!" meanwhile Ren say "For me it ok to go to the park with all of you but I want to ask dad if he can teach me how to unlock , mold and control chakra"
Kizashi and Mebuki look at each other while Sakura watch confused, then Mebuki ask "Dear why do you want to learn that now you will learn all of that and more at the academy?" 'I do not want to tell the truth that I want to learn to escape a horrible death in two attacks on konoha, a fourth shinobi war and a fucking alien invasion' think Ren so he replies "I heard from Shikamaru and Chouji that their parent already thought them the basics and even if it is annoying it'll make the academy easier"
Mebuki thought about it for a while and then nodded "Ok while I watch over Sakura your father will teach you" then turn to Sakura "Sweety do you want to learn about chakra too?if you want I will teach you tomorrow"
Sakura think about it and then nod "Yes if Ren learn about it so will I!" Mebuki nod then said to everyone "Ok now finish breakfast and prepare for going out and remember to wash your teeth"
Finished eating both Ren and Sakura go to bathroom to brush their teeth and then into their room to dress after that they meet with their parent and all together got out of their apartament then out of the two stories yellow building and went in the park direction.
There they met with Ino and her mom and while the adult talked to each other Ren and Sakura talked with Ino who greeted them with a smile "Sakura,Ren-kun happy birthday to you" and Sakura soon respond with "Thanks Ino now let's go to the flowerbed!" Ino has fair skin, light blue eyes, and long platinum blonde hair worn in a ponytail, with bangs framing the right side of her face in general a pretty cute child.
Ren replies to Ino "Thanks Ino-chan please take care of Sakura while I'm training with Father" Ino then confused ask "Training?What?" instead of Ren is Sakura answering "He want to learn about chakra so that he can keep up with Shikamaru and Chouji"
Ino lose interest and say"Oh...it's about that yes my father started teaching me that too only it is too boring it is more fun playing with Sakura, let's go!" she takes Sakura hand and lead her to the flowerbed soon after following the two at distance are Mebuki and Ino's mom.
Ren then turn to his father and say"So dad where do we start?"Kizashi look at Ren and for once he is strangely serious"Ren what i'am about to teach you it's not for playing with your friends it is a tool used to protect yourself and your loved ones do you understand this?"Ren replies soon"Yes Father"
Kizashi nod and star explain "First of all you must know that chakra is essential to even the most basic jutsu. Through various methods, the most common of which is hand seals, chakra can be controlled and manipulated to create an effect that would not be possible otherwise, such as walking on water, exhaling fire, or creating illusions. Chakra is ordinarily not visible to the unaided eye unless it is highly concentrated or manifested in large amounts"
'Oh my god, dad became like Wikipedia of my previous life, how is possible that my goofy father is like an encyclopedia... so mine and Sakura good memory come from father what a surprise...or not dad always told us that our mother is a taijutsu specialist'
Meanwhile Kizashi continue"Produced within and manipulated by organs such as the heart, the energy circulates throughout the body in a network called the "Chakra Pathway System", which is similar to the cardiovascular system. Groups such as shinobi have learned to generate more chakra and release it outside their bodies through pressure points called tenketsu in order to perform jutsu."
And goes on" Chakra is created when two more primal energies, known collectively as one's "stamina", are moulded together. Physical energy is collected from each of the body's cells and can be increased through training, stimulants, and exercise. Spiritual energy is derived from the mind's consciousness and can be increased through studying, meditation, and experience. These two energies becoming more powerful will in turn make the created chakra more powerful."
And on"Therefore, practising a technique repeatedly will build up experience, increasing one's spiritual energy, and thus allowing more chakra to be created. As a result, the ninja is able to do that same technique with more power. This same cycle applies for physical energy, except the ninja needs to increase their endurance instead. Some unique individuals have substantial potential that enables them to exponentially increase their chakra reserves in a relatively short amount of time"
