Anger management Oni suggestions

So recently I did what I call Ice cream man Doctor using perks that revolve around him trying to serve Ice cream to the survivors so now I want to do a build call Anger management. My boy needs to try controlling his anger so he needs a good build to do so. Now it might be similar to No power Oni where you bring Renjiro's glove but I want to make it a little more different. Any suggestions?
