They called her the Devil of the Underground, an S-class criminal who single-handedly slaughtered the corrupt nobility of Mitras. But to humanity's strongest soldier, she was simply Sin-the unhinged, obnoxious girl who had raised him in the dirt and vanished into the shadows years ago. Now forced into a lifelong enlistment with the Scout Regiment as a shield against her execution, Sin steps into the light, trading her blades for the green cloak of the corps. Bound by a transactional contract to obey every order, she must navigate the terrifying world of Titans.

Cassandra Blake knew how Attack on Titan ended. She knew who would die. She knew who would betray humanity. She knew which screams were coming before the people around her even learned to be afraid. Then she fell asleep in the modern world and woke up in Shiganshina on the day Wall Maria fell. Trapped inside a story built on sacrifice, Cass joins the 104th Cadet Corps with the weight of the future locked behind her teeth. She knows too much, moves too carefully, and somehow always seems to be in the right place when death comes reaching. To the military, she is suspicious. To civilians, she becomes something dangerously close to hope. To her friends, she is the girl who laughs with them, fights beside them, and refuses to let go when the world tells her she should. But fate does not break quietly. Every life Cass saves changes the path ahead. Every secret she keeps draws sharper eyes toward her. And in a world where survival already demands everything, Cassandra Blake will have to decide how much of herself she is willing to lose to keep the people she loves alive. Because knowing the future is not the same as saving it. All credit for Attack on Titan and its entities belongs to Hajime Isayama. I only own Cassandra Blake and pieces of the divergent plot.

In a world consumed by chaos, where man-eating Titans roam beyond three towering walls that barely keep humanity alive, survival is never guaranteed. Fear governs the hearts of many, and hope is a fragile thing, easily crushed beneath the weight of despair. But fate takes an unexpected turn. Amidst the struggle, they encounter a peculiar individual. Someone who does not belong to their world. A being whose presence defies reason itself. A person from another world. At first, they are met with doubt, suspicion... even fear. Yet as battles unfold and humanity teeters ever closer to extinction, this stranger reveals power beyond comprehension. Something neither Titan nor human could rival. Not merely strength, but something greater. Something divine. Again and again, when all seemed lost, this being stood between humanity and annihilation. And so, not by title alone but through undeniable proof, they came to be known as HUMANITY'S GUARDIAN.

Hope Rose joined the Scouts to save lives, not take them. As a medic with a quiet fire, she's spent her career away from the battle-stitching wounds, calming panic, and hiding the scars no one else sees. Levi Ackerman doesn't notice people. He notices efficiency, weakness, and tactical errors. But when he is assigned to train Hope to join them in the front lines, he finds himself noticing her. Too often. Too deeply. And that, more than any Titan, terrifies him. Through forest missions, political conspiracies, near-death encounters, and the quiet stillness of after, a bond forms. First in shared silences. Then in stray glances. Then in something neither of them can name. In a time where peace is fleeting and grief is constant, Levi and Hope must decide: is surviving enough? Or is it time to start choosing to live?
