small point about p.7
he was earning 20 billion a month when supplying energy to Japan
which is 666,666,667 per day
which is 27,777,777 and change per hour.
and if he paid 100 million to the loan sharks, then he spent ~3.6 *hours worth of money.
I don't recall how long he was doing that job at that pay scale, but that "tiiiiiiny bit lighter" bit just made me wonder.
*Also it behooves to double check when editing a comment for content that you get the correct unit in the proper place in the sentence.
