So future loki teams up with other Evil Gods and one from another world (possibly the same one with Chichigami) to change the timeline of every parallel world they can find.

As it is mentioned, they have already affected the anime timeline hence BorN, but regardless Issei and co. still won in the end even without the help of Chichigami, so their evil plans kinda failed at that one.
