Zetman

Both of these series starts off as tragedy stories after a startling revelation is made.
From there, the main character tries to become someone they never thought to be and get justice. Along the way, both characters meets others whom they bond but also conflicts with.
In both of these anime(s), there is action, violence, and drama. There is also comedy (less so in Zetman), and even very tiny hints of romance.
