Attack on Titan's Fate

"Change? The price... Can you really afford all this?" At the end of the road, the man who looked exactly like him whispered a cold prophecy. Kallen Cappe is a heterogeneous person with the "blood of kings" flowing through her. He longs to protect everything he values—family, friends, and lovers. However, the collapse of Wall Maria tore his world apart. In the blood and fire, he swore an oath: Kill all the giants! This determination ignited the sleeping blood in his body. The sweat and emotion of the training corps, the life-and-death fight in Troost District... The short-term happiness is like a bubble. When the figure of the female giant tore apart the Survey Corps, Kallen's world instantly collapsed - the cold killer was his true love. Guard? Expose? Destroy? Beloved is a mortal enemy, blood is a curse, and prophecies of the road are like shackles. (The style is biased towards the original version, there is no time travel and no system, the plot is basically original, and a lot of my own original settings are added) In the giant web of lies, in the bloody torrent called "fate", Kallen grasped the power of her double blades and launched the final charge against the destined tragedy. Thousands of endless reincarnations and the variables this time, can he tear open the iron curtain of fate? Or will you fall into the abyss together with the one you love?
