With the Second Wall now breached in Attack on Titan, Vol, 1, the 104th Training Corps is thrown into the battle, despite having just graduated. Unaware that Eren has fallen and has been swallowed by a Titan, Mikasa, the best fighter to ever come out of training, leads a platoon of troops, looking for her brother and protecting civilians. Mikasa's traumatic childhood is explored, including Eren rescuing her from slavers who murdered her family and who were bent on selling the last Asian to the underground flesh market. 

At the second gate, a merchant and his cargo are blocking the evacuation route for remaining civilians, and Mikasa intervenes, letting the merchant know in no uncertain terms that if his death is the cost of letting people through, she will gladly pay it. The merchant agrees to let the civilians flee.

Meanwhile, Titans are attacking the Second Wall's headquarters, where the gas necessary for the 104th Training Corps to scale the wall to relative safety of the Third Wall is stored. With no gas, Mikasa leads her troops to battle to rescue those under siege with a daring plan. But then a strange thing happens. A Titan ignores the humans, and instead begins to attack other Titans, causing enough of a distraction to allow the humans to rescue their friends and refill their gas canisters. It is almost as if the aggressive Titan wanted to protect Mikasa ...

The story continues in Attack on Titan, Vol. 3.
