In episode 34 Near asks Mogi how long you can manipulate a victim before their
death. He replies 23 days because the Yotsuba incident proved this? When in
the data from the Yotsuba incident was this proved?

When was the 23 day rule in Death Note revealed?


It was revealed because of Misa in chapter 48. Higuchi promised to stop
killing criminals, so he could marry Misa, the second _killer_ and he did. But
because he had written down lots of criminals already, the deaths kept on
continuing for 23 days until they stopped. From this they could deduce the
killings could only be manipulated until 23 days in the future.

The death note that was dropped by Ryuk contained all the known rules
including the 23 days rule. After Light made the Shinigamis switch the books,
Yotsuba got the one with the rules that later came to the investigators.

The "fact" that the deaths stopped after 23 days is wrong btw. They explicitly
stopped immediately because he never wrote a date of death for criminals.
