Sweet timing! I love seeing the two divergent story lines converge. Ichibumi must have a lot more to do with the anime storyline than the average author of an LN. Otherwise, considering all the production and prep time that goes into the Anime, the timing and obvious similarities would not be possible.

Also:  Do we know where the doppelganger went?
