This is somewhat explained later, but it's not a huge spoiler, so I'll just say it. They honestly just didn't bother to check. Using your sensor radius to sense chakra is something you have to do willingly; it's not done automatically. Since they had no reason to suspect him, they simply didn't check.

ive been thinking about this im very unhappy with the first 30ish chapters

Who knows :)

There will be but im not sure how heavy it will be most likely it will be very light

If he were supposed to have kage-level chakra, he would now have 50 times that level.

I think you're talking about his dad, but he didn't die either.

His mother doesnt have an ms and shes not dead.?

?

I know they get longer though I promise

I think this eventually gets brought up but no he doesn't keep his progress towards his chakra reserves or his body development but he does keep his chakra control and things of that nature.

he died at he end of the 1st war

oh ok I see

I meant it as Izuna isn't the same person Madara was, not that he isn't Madara's brother.

You also have to remember that Izuna was a 20-year-old in a baby's body, so his brain is a little more developed.

I am not going to say I know how old Fugaku is supposed to be, but I've done a lot of searching on this since I wanted to be as accurate as possible and also due to people saying this constantly, but the only thing I could ever find was that there is no cannon age for fugaku so I just made one up.

definitely

People keep saying ROB, what is that??

This is the 2nd or 3rd time I've seen ROB what is that?
