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 nearby supply depot is overrun by Titans. Mikasa seems unfazed after learning from Armin that his entire squad perished, including Eren. She rallies the others to reclaim the supply depot, inspiring them to join her in the attack, but Mikasa ends up running out of gas midair and falls into an alleyway. Jean assumes command, but he loses his nerve when he sees some of his comrades being eaten by Titans. As a blonde Titan approaches Mikasa, she prepares to attack with her remaining broken blade, but a mysterious Titan appears behind her and brutally kills the blonde Titan, much to her confusion. Armin and Conny show up, shocked to witness the mysterious Titan not only fighting other Titans, but also showing knowledge of their weak point and using hand-to-hand combat techniques, while completely ignoring the humans. Armin gives Mikasa his gas tanks and blades so that she can support the others at the supply depot. Mikasa, however, refuses to leave him behind and ponders on the mysterious Titan’s strange behavior.
