king_of_gods_

There is the next chapter in which I will explain the parallel time of MC in konoha, don't worry i will cover everything at all costs.

that's why her character is slightly dumb like karin uzumaki, but i have also added kagura mind's eye ability to sense someone nature whether it is pure or malicious in chapter 53

I will not say about the chakra control but obviously Naruto's body being an uzumaki descendant is more powerful than hiruzen. and after his training with jiraya his body becomes more powerful. but hiruzen can meet this strength with his taijutsu skills none the less and breathing training after some time. as for boruto controlling rasenshuriken he can do it with exceptional chakra control but others don't have such chakra control so hiruzen made it as others too can learn and use it.

he didn't kill him, he will perform an experiment on him to create a jutsu in future, danzo is in a suspended animation state

cause Minato didn't get out of the village after he became hokage and in the nine tail attack he died.

well the S-rank jutsu like these can't be used without a powerful body and sage arts, so hiruzen created two rings surrounding it to contain the cutting force of wind from injuring the user and such that a ball of blue and white rasengan with 2 rings revolving around it is formed. that's why traditional rasenshuriken and wind rasengan is different and can be used without sage arts but require immense chakra and control

at the border of land of whirpool. cause konoha or fire nation and land of whirpool border touch each other

vote for hyuga and suggest others also if you can make other vote for hyuga it will be selected as well

akeno himejima as a wife and Asia namikaze and even others can be selected
