7. Small Blade - The Struggle for Trost (3)

Complete story — includes the ending

The surviving squads, unable to reach the inner walls due to their omni-directional mobility gear being low on gas, lose their fighting spirit as the headquarters and supply depot are overrun by Titans. Mikasa learns from Armin that Eren is dead. She rallies the others to reclaim the supply depot by taking down the Titans but runs out of gas and falls into an alley. Jean assumes command, but loses his nerve momentarily when he sees his comrades being eaten. He eventually makes a judgement call, leading his surviving team members to headquarters. As a Titan approaches Mikasa, a mysterious, black-haired Titan appears and brutally kills it, much to her confusion. Armin, Conny, and Mikasa are shocked to witness the mysterious Titan not only fighting other Titans, but showing knowledge of their weak point and using hand-to-hand combat, while ignoring the humans. Armin gives Mikasa his gas tanks and blades so she can support the others, but she is unwilling to leave him behind.
