Even when he smiles he creeps you out, what a unique guy Mayuri…
Unless you are Kisuke, don’t ever follow the “rabbit” that is Mayuri down the hole towards the “Wonderland” that is a world of torment and suffering waiting for you thanks to his drugs and unnerving taunts. Toushirou should have just died and saved himself the mental anguish and suffering he is currently subjected to. To be caught inside some ridiculous scrapping of reality, I too am bemused at the exact functionality of Mayuri’s drug which he administered to Toushirou at some point during their battle in a yet-to-be-revealed way. Whatever the case, Mayuri’s smile when caught up in his excitement over torturing others is quite the chilling gesture.
