The punishment for losing the race came to Stanley just as the previous punishment had been. He had received the lowest punishment for the dancing game which had gotten rid of his ability to constantly view the future for 3 hours.
Receiving the highest level of punishment, Stanley had now learned that he was barred from using another one of his powers. It was his power to slow down time.
As for the duration of the punishment, there was no duration. Instead, there was a requirement to unlock it.
If Stanley wanted his powers back, he needed to kill 100 different people with power. Killing Novas counted for 10.
Stanley remained wide-eyed in the white room as he learned about his punishment, realizing just how horrible of a punishment it was.
Not only was what was possibly his best skill affected by the punishment, but he now had to kill people to make it work again. People… he did not want to kill anyone.
