Attack On Titan Akame and Levi are equal in strength and power. Nobody knows that they both were raised together when they were younger in the Underground. Levi taught Akame the basics of fighting both titans but Akame taught herself more useful skills, similar to the ones of Levi. Levi keeps this a secret and doesn't show it but he secretly loves Akame while Akame sees Levi as a big brother. (Gonna make changes along the way so feel free to voice out your thoughts)
