Nightwing is after a serial killer known as The Shrike. However, in doing so, he runs into a strange person who claims to know him from long ago. While he won't get a straight answer out of this person, will this wannabe become an ally?
Where does this take place in my timeline? Certainly pre Intro Arc, and could be used after, or in lieu of, The Return of Damian Wayne (depending on whether certain rumors will be true).
Who is Shrike? Well he's my take on an old Nightwing villain, but with a New 52 twist you'll find out in future parts
As for what is going on NOW in the comics (WARNING: SPOILERS!).
It wouldn't be that much of a stretch for Batman to figure out a way to discredit Nightwing's reveal during Forever Evil
. And Higgens has been planning a Mask Killer arc for Nightwing (which is referenced here). So in my head canon/crystal ball, these things happened before this tale.
And yes, the "ninja"'s little grapnel device IS inspired by Attack on Titan
(Just got into it, I literally watched 16 episodes this weekend)
Hope you enjoy it and stick around for the ride!
