Academy City’s newest corrections facility offers a dark bargain: The Jailbreak Challenge. It’s said that anyone who runs the dangerous gauntlet of security systems, rescues their target from imprisonment, and escapes with both their lives intact is entitled to an impressive prize: One billion yen. Cash.
Deep in the trials of the Challenge, Mikoto, Kuroko, Uiharu, and Saten find themselves up against desperate odds–as well as every force in Academy City with an eye for the prize.
This volume begins plot after the 3rd season of the anime (Railgun T). The Jailbreak Challenge brings back many secondary characters and introduces some new. There is a lot of humor here, making this a light read. The end sets us up for more serious doings later on.
You get two for the price of one here; the story in this volume is complete and enjoyable all by itself. It is also setting up a larger story for the two remaining volumes.
