Batman and the Outsiders 11 - Pages 1-5
"A Sword of Ancient Death" AKA "The Truth About Katana Part 1" by Barr and Aparo starts off in a darkened Gotham City alley, in a part of town neither Geo-Force nor Katana really knew (they're not natives), and are just now finding out is crime-ridden. I don't know how that distinguishes it from other neighborhoods in Gotham, though.
(I've never felt so close to Geo-Force.)
Next time: Find out what Katana bought Halo in that bad part of town. Also, the ninja actually does some ninja stuff.
