I mean, Buff is right here.

However, Iīm still more disappointed that they didnīt explain the time jump ability. Again, not explaining it is lazy writing. Without the time travelling, itīd be a simple, traditional murder crime story. So the author wants to make something special and introduces time travel. Which is fine. But then he never explains it. Which is not fine. I guess some people like shinta are more forgiving because itīs a subtle power. Now imagine Satoruīs ability was to shoot a Rasengan, something everybody can witness. Would you still be fine without any explanation?

I think itīs weak.
