Censure
If you want to slice the power out of someone just censure them. Then they'll be cut down in front of everyone and they'll feel super embarrassed. It's the best way to slice them down without actually cutting them and getting arrested.
Picture yourself as you slice the power out of that senator you hate by censuring them in front of the world!

Once you censure them and they lose all their power, they'll be just another guy (がい). A normal guy with everything lost to him. HAHAHA!
Look at that guy now. What a loser.
