Rinnegan As Option

"Are you full yet?" Ichika asks Kushina, as he knows she might not be, as she is a 'big girl'.

"Am already full!" Kushina still being a girl and being asked if she is full, offended her as a girl, Ichika didn't understand girls but he tried to understand her.

"Sorry," Ichika apologize.

*Humph* as she walks faster.

Ichika and Minaro just follow her, Ichika isn't romantic with her, and he isn't interested in a child, as an adult he might consider it.

"Bye" Minato and Ichika broke the silence as they walked home, they actually dropped Kushina home before going back.

"I need a lot of food" Ichika was thinking of how to make money, currently he only has an amount of 100,000 ryō in his savings account; more like he saved them under his bed. 

"100,000 isn't enough, it'll be able to sustain me for around 2 months" Making his plan with that limited amount isn't good. 

He also knew that using the Military Rations Pill wasn't a good thing. While it might contain everything that the user needs. His focus was to train his body so he could use chakra again not to train his chakra as his mental energy is too much for the chakra to maintain.

"I need to extend the time frame to 6 months before I can use chakra again, and during that, I also need to make sure that I keep my grade in the top 10"

The reason why he needed 6 months was that he needed to able to handle the Rinnegan ability; not fully but using smaller versions of those Jutsu. He only needs 2 months to be able to use the chakra again.

He doesn't need to learn any other Jutsu as he can just use his already learned Jutsu regularly, the Rinnegan ability to enchant the user's chakra significantly but a large amount that he can just use the basic Jutsu to beat other Genis.

 That night Ichika decided to divide his time into 4 sections. 8 hours dedicated to sleep as his body wasn't big yet and only a small little boy. 4 hours for school, he was already smart compared to anyone in his class, and he could maintain the theoretical knowledge grade high. The last 10 hours are divided into 3/7, 3 hours for interaction whole the last 7 hours for training.

The last 2 hours are for everything such as showering, eating, and other thing.

"This should work if nothing goes wrong" his schedule is going to be the fullest it could be, and there is nothing that he could do but accept it.

While other people think that this is too brutal, he doesn't as the Second Shinobi World War is soon happening.

With the plan done, he grabbed his warm milk and drank it before going to bed.

"Good morning" Ichika woke up, well he didn't expect anything to happen soon.

With that, he got up and finished anything, walked to school, finished the class, played with Kushina and Minato, left, and trained for the rest.

He trains his body but he doesn't use weight as they're going to have too much pressure on his body already. He mainly focuses on cardio.

After finishing the training, he returns home and makes his food, he makes sure to add everything that he needs, also he make sure to eat more than regularly as he eats more. He going to lose a lot of weight anyway just from training.

He repeated this for a week and found out that it should work in theories, but it doesn't work in practice. Section for school (4 hours) and exercise (7 hours) work but the sleep (8 hours) and friend (3 hours) doesn't.

It doesn't mean it was a failure, it just meant that he should adjust the timeline a bit to fit everything in.

He going to take his free time (2 hours) and divide it into one hour, and the other one hour into for his sleep and friends so that they get more time.

This also means that he needed more time to sleep.

During the training, he found that he couldn't increase his stamina as before they were already good.

He probably needs to use the practice of that ' Demon Slayer'. Their breathing style helps them fight and also enchants their physical strength to match that of the demon. 

With the new change, his body now has more time to sleep, and because of the change Kushina now drags Ichika for 30 minutes more.
