[Discussion] Switch between worlds

[Meowazziel]

Anyone can potentially switch between worlds if you are dead and have chakra right?
Its not like you need Kamui for that, so why did Obito use it to get to Kakashi?
Is it required or not?

Where does it say you can switch between worlds anytime you want?

Where does it say you can switch between worlds anytime you want?

In the second spoilertag it says:
''Our chakras have the power to connect worlds'' and when Rin asked ''could you get there immediately'' Obito's answer was ''yeah''.
It doesnt say anytime you want literally though. He could at least go there right now.
However that is not important.

The question in the thread was, why use Kamui for switching worlds?
Just for coolfactor, but it can be done without? Or it is required?
That is what the thread is about.
