@HoangDinh There was going to be a lot of fuzzy logic involved in any case. He can, for example, move people around, change their poses, remove their clothes, cook food, and so forth when time is stopped. I'd assume that as long as something is triggered or caused by him (or Gankichi), it will still happen even during the time stop. So, if he steps on the trap trigger during time stop, the trap will activate. However, if someone else had just stepped on a trigger before he stopped the time, Sekai could still move the person's stiff body from the trajectory of a bolt frozen in air, for example.
