Tsunade’s birthday wasn’t big, the first half of the day was a small party with her family, while the second half happened at a restaurant with Jiraiya and Orochimaru.
The hokage came for a short time as well but it wasn’t anything fancy.
The morning of her birthday, Akira, Kushina and Nawaki all woke early to help Mito with breakfast.
Akira wasn’t much of a cook in his previous life, but he knew his way around the kitchen.
After setting the table, Tsunade came out of her room, still yawning.
“”””HAPPY BIRTHDAY!”””” they said in unison.
Tsunade froze, then a warm smile was plastered on her face.
Breakfast included alot of reminiscing.
Nawaki’s nerves for the first day of the academy, Akira and some very embarrassing moments when he was a baby and Mito recounting when Tsunade’s gambling addiction happened.
Everyone laughed, even Kushina, especially her.
She was starting to feel like a real part of the family.
After breakfast came gifts.
Nawaki gave her a cook book in hopes she could make actual edible food.
Mito gifted a nice pair of shoes that Tsunade immediately fell in love with but when it was Kushina’s turn, her face turned dark.
The good luck charm sat in her palm, silent.
Tsunade was ready to bonk Kushina’s head for mocking her gambling skills, but Kushina was faster, hiding behind Mito.
Lastly, Akira pulled out a scroll, detailing the method to add a second reservoir to the yin seal and the breathing technique.
He even wrote down the ideas for the ninja art creation rebirth – strength of a hundred technique that Tsunade created in the future.
Right now the yin seal was just a reservoir for chakra, where a small amount was used passively to maintain youthful looks but in the future Tsunade found a way to use it properly.
After inventing the creation rebirth technique, a technique that can forcibly stimulate a person’s cell division by releasing massive amounts of chakra, she linked that to the yin seal creating the creation rebirth – strength of a hundred technique.
Akira didn’t know enough medical knowledge to invent the creation technique, so he only outlined how to use the chakra stored to boost any technique that uses chakra.
Tsunade’s main techniques were the chakra enhanced strength and medical jutsu.
Given her genius, she could definitely create her signature jutsus from canon earlier.
After Akira finished explaining, she pulled him in for a hug.
He never understood how those Japanese protagonists always ended up suffocating from hugs with girls until today.
‘Those things are dangerous, and she’s still growing.
Luckily Kushina pulled him free, though not without giving Tsunade a look filled with jealousy.
After the birthday Akira decided to get started with the yin seal himself.
His chakra control was still only at tree walking level, but it was improving quickly.
He estimated that by his birthday next year it would be sufficient.
His fuinjutsu skills, along with Mito and Tsunade’s guidance meant he would finish it quickly.
With the second reservoir, he would have enough chakra for daily use and still be able to store the excess.
Sakura took 3 years to master it only because she had smaller chakra reserves, and she was also learning Tsunades medical knowledge simultaneously.
Akira’s chakra reserves were huge thanks to the purity of his bloodline, and it was steadily growing as his body got older and stronger.
With him starting physical training, it was the perfect time to store any leftover chakra he didn’t use during the day.
This would mean that he woul to never have to worry about chakra cost, much like Naruto and Hashirama, who could use very powerful jutsus.
About a month after Tsunade’s birthday, along with Akira’s life falling back in the same rhythm, he awakened another Uzumaki bloodline ability: the adamantine sealing chains.
These chains can be used to bind and nullify opponents chakra, even tailed beasts don’t stand a chance against it.
They are also very durable, so durable that even the nine tails couldn’t break them.
Kushina, during the nine tails attack, also used these chains to create a barrier that prevented the nine tails from leaving and the third hokage from entering.
This can be done by layering a barrier between two or more chains.
Akira only managed to create 2 after awakening, and the length was only about 20 feet, but just like with Kagura mind’s eye, he had Mito’s help.
After Akira awakened the chains, Mito readily added it to his training schedule.
Before, she might have been worried about Akira not having any friends, but with Kushina here, that wasn’t a problem at all.
Speaking of Kushina, after seeing Akira’s talent and diligence, she started to take learning more seriously as well.
“Grandma, can I awaken those technique techniques too?” Kushina asked.
“Yes my child, you have extraordinary vitality compared to other Uzumaki children, so don’t worry about not Awakening them. Akira is just a special case.” Mito replied, stroking her hair.
Akira, however had his mind elsewhere.
‘My workload is increasing, I need to get the multi-shadow clone technique.’ He thought. This story is hosted at g.com.
The question was, how?
He needed to convince his family that he could bear the risks of shadow clones.
The first risk being the large chakra requirement, which he no doubt passed, given his jonin level reserves at 4.
Since shadow clones take exactly half of the user’s chakra, making multiple could lead to exhaustion.
That’s why only ninjas with at least jonin level chakra can attempt normal shadow clones.
And the second risk being the influx of knowledge that comes when the clones are dispersed.
Tobirama created this technique to help scout for information without risk to the main body, unfortunately this also caused huge mental fatigue if used recklessly.
The only way Akira could think of to deal with the second risk was the last Uzumaki trait that Karin awakened, high vitality that gave the users blood unique healing properties.
Essentially,healing bite.
Akira wasn’t worried about awakening that ability, his bloodline was very pure, probably even higher than the Sage of six paths to be able to get rinnesharingan in both eyes.
Even Kushina, with her higher than normal vitality could awaken it, Akira just needed some time.
And given that he just recently awakened the adamantine sealing chains, he guessed he didn’t have to wait long.
With the healing ability, Akira would have no trouble dealing with the consequences of shadow clones, he could even sustain the multi-shadow clone jutsu given his pure bloodline.
Though Mito probably won’t allow him to use that technique.
He understood her worries perfectly.
To her, he was still a child, even with the healing ability, getting all those memories might alter his personality, making more mature than he already is.
Unfortunately Akira had a reason to get stronger quick, the Second Shinobi War.
Akira remembered it starting around the time Minato was twelve, so he only had eight more years to reach Kage level, if he wanted to protect himseld and his family and live happy lives together.
So he had to rely on his other cheat ability, being Mito’s grandson.
This cheat ability came with a nice perk called Tobirama’s notes.
With this, even though he might not be able to get the technique itself, he would be able to reverse engineer the multi-shadow clone jutsu once he had the normal shadow clone jutsu.
From what Akira could tell, the difference lay in control of chakra.
The normal shadow clone precisely divided the user’s chakra in half to make a clone, whereas shadow clones roughly divided it.
That was why multi-shadow cloned was a Forbidden jutsu.
Recklessly dividing chakra, which was composed of both spiritual and physical energy could lead to death.
Even though it was risky, with Akira’s general understanding of the jutsu fron his memories, combined with Tobirama’s notes, it was only a matter of time.
