worldbuilding / self-lore
time travel exists in Kaito's world but it's useless for all the things you'd probably want to use it for
you could, in theory, load a backup of the entire world into a separate instance of the world's "program" and explore it
but not only can you not guarantee that the actions that occurred in that sub-world after you started running it were identical to what happened in the "canonical" version of events
you also obviously can't make any changes that would propagate
@KS ...are boobs a magical power? :P
