This letter is from Asagi... oh!

There is an old trick that people have been using for ages to get things through the council without swinging a sword.

First you concentrate all your bribery on a single high level senator. Then you simply toss all the lower level senators into that one and bam! You have passed the bill! No force involved~

Demons are much more likely to give you want you want when you don't kill them, especially when you massively increase their level as a result~
