Man, it doesn’t happen instantly, I already explained this. Just because it’s a thought based ability doesn’t mean the activation speed is the same as the thought speed. I can give a very simple example, Eida. She desired something, and her ability activated afterward, but it didn’t happen the moment she desired it because there was a time for the ability to activate. If you can’t find a panel or evidence showing that Shibai’s ability happens instantly, whatever you say will remain as speculation, it’s that simple. Additionally, if you can’t support your claim that it "happens instantly" for physical results, the 15 different things Shibai is supposed to do would also be delayed.
