6/10.
The Queen of Cups in ninja wraps. If she were a Jedi, she'd be a healer. Seen it.
That said, with a more "calm, kind, reserved" (read: "introverted") personality, what we're seeing isn't exactly the important part, huh? What makes or breaks the character in terms of originality would be her descriptions of individual environments and what she remembers in people.
Was for Alaki^
As for Cross --
Military in occupation, but not in appearance. Brains, experimenting on biological, mechanical, and apparently military systems. Gets drunk, presumably on duty, but suffers no consequence of drinking. Maintains an unhealthy physique for military service. His one weakness? Can't use big guns, (but he's a cowboy with smaller ones). Has been alive forever.
9/10. Mary Sue or Anime Vampire.
