Wouldn't it be funny if many of the money was wasted on Kuro so that this guy can escape the tax police?

One of main reason why Mysta left Niji was because Anycolor refused to help him with taxes, and knowing that Gunrun was full steam on poaching and learnt that one of the Luxiem boys quit, I wouldn't be surprised if he tried to bait him with the "lemme help you with the taxes", and it worked

They helped him by withholding his income so he wouldn't have to pay more taxes on it.
