Two of my characters in my friend RaineOuShine's world, specifically my main protagonist and antagonist respectively, Aki and Darkflame. Since I made them both as a kid, they've gone through a lot of development, with their fair share of parallels despite how different they are (such as their powers both having to do with destruction, Aki through natural decay and Darkflame through fire). The white lines resembling a cube kind of represent their differing paths, but they are ultimately on the same starting point.
