I thought it was actually quite ingenious that the Irathian superpower involves people seeing... the past...
Usually it's all "It is the future you see". I can live with people seeing the past, a lot easier to suspend my disbelief.
On the website, there's a deleted scene from the start of episode 2 of Irisa having a vision of the future, specifically the end of the episode. I'm hoping they cut it because they decided not to let her see the future, but I won't be surprised if they do give her precognitive visions in later episodes.
Didn't the leader of the Spirit Riders kind of imply Irisa might be able to see the future?
