Both are sequel series that feature a plot-driven continuation of the original work, which is more character-driven.
both feature a teen/young adult who was previously timid and bullied, trying to live their lives normally after committing a life-altering act of violence that has hardened them into numb, unfeeling people with soft spots for those they care about
both lead characters are extremely weak at first, yet refuse to back down, either using their perseverance or intelligence to battle against stronger opponents despite their physical disadvantages
both feature the main characters getting caught up with a larger organisation, and personally attacked by the leaders of said organisation, whom they must battle with using hand-to-hand combat
both are tales of the underdog who only fight to protect the people and friends they love
