In this world it's mixed of dandy's world and the world of attack on Titan pure Titans Rome around killing people by eating them so everybody built 3 50m walls wall Maria wall rose and wall Sina scouts guard the walls they are equipped with gear that allows them to fly in the air with hooks that attach to things like a grapple and gas tanks propel them they can run out though and they carry 2 blades with 4 sets of more blades on the waist pure titans:pure titans have a size range up to 7m-20m they are naked but have no genitals shifters: shifters are a Titan that ate a different shifter and turned into a human but they have the ability to transform into a Titan by critically injuring themselves they are still naked and don't have genitals but this time when they exit their Titan they come out though the titans nape which means the weak spot of a Titan is the nape a Titan is a completely different body which needs the shifter because without the shifter they are dead but Pure Titans don't rely on shifters the bigger the titan the more hot it is
