Rolando found a piece of promotional art (thanks!!) for Compile Heart’s strategy RPG mashup and it reveals a few more faces. The original image was tiny so it’s horribly scrambled when expanded, but you can clearly see Lilith from Darkstalkers will make an appearance in Cross Edge. Lyner, the male protagonist of Ar Tonelico, has a role in the game too. Also from the Gust side I believe Whim, one of the characters from Mana Khemia 2, is right above Roze.
The center of the poster is where things get fuzzy. Characters show their backs instead of their faces. I think this group might be part of the Neverland universe, but this is more of a guess based on the artwork than concrete cape recognition. Let’s take a look at the updated roster of non-original characters in Cross Edge.
