Born with the Spine that saved Ymir, [Y/n] summoned the 10th Titan Shifter, the most powerful of all. It has every fragment of the Nine Titan Shifters and does not have the curse to live for only 13 years, but it has one weakness. The person who possesses the Spine will always submit to the Royal blood and holder of the Founding Titan, and the only way to set her free was for an Ackermann to slay her. Because [Y/n] summoned the Spine's power, Marley sought after her to be used as a weapon, making her a restless wanderer. Until a boy named Zeke Yeager rescued her. Taking her in until she escaped for Paradis Island, where a Commander found her and adopted her as his own. Growing up on the island of devils, she became an endowed soldier helping humanity. But little did she know that she was entering a game of life and death wherein she is omniscient. ♚Based on the Manga/Anime with a little twist♛ Whose side are you on? Marley? Paradis? or Yeagerist?
