Eh, not all edgy types are in the Dark attribute. There is one particular Aqua unit who is also edgy. If you've noticed yet, there's a color pattern to the names in the navigation list. The color is a callback to what their original types in MagiReco is. Red = Flame, Blue = Aqua, Green = Forest, Yellow = Light, Purple = Dark. Though it appears that people's requests are skewed toward Forest units so far.
