-Non playable characters-
Gilgamesh- Yep, I'm gonna be there! I, being the headmaster of the CCA, have a nice big role in the story, of course. Although I'm quick to use my authority over members of the CCA and the villagers who live in or around my castle, Chun-Li will be following her own instincts rather than going on missions based on my own lame advice. ^_^
Ash Rigo- As can be expected, I'm not the only CCA member in the game. Although several other CCA members will make appearances in the game (okay, probably all of them), by far the most important one to the plot is Ash Rigo, Gilgamesh's second-in-command.

The CCTS- Ramza Beoulve, Morrigan Aensland, Shayla Shayla, and Sakura Kasugano are the other members of the CCTS, an elite team of heroes brought together by Ash Rigo to combat the injustices of the world, but usually just stumble upon them while they're screwing with something else.
Leon S. Kennedy- RPD's finest rookie spends most his days hanging around the CCTS HQ with Morrigan. Although he has a strong sense of justice and fights for what he believes in, he is easily distracted by shiny round objects and therefore is not much of a help, really.
Cassandra - The only other survivor of Alex's hometown, Cassandra is Alex's childhood friend and the last member of an ancient race, and she may or may not be the rightful heir to a kingdom currently being governed by a corrupt tyrant, we're still working on that part. ^_^ For some inexplicable reason, she's madly in love with Alex and all but throws herself on top of him, but of course Alex is too damned stupid to notice. What's a girl to do?
Roan - Another character from Grandia II, Roan is a young boy who loves adventure. Though he and Millenia would appear to have very little in common, they are actually good friends.
