"D" is an ancient lifeform who was ressurected with the help of technology. She is also the pilot of Core Robot 3. Her
robot is usually the first one to be out of the fight. I'm not sure if it's D or the robot that's weaker. D has a special
and mysterious connection with Kazuki. She will openly talk with him. D is usually very quiet though. D also has a connection
with the artifacts. D adds a different kind of humor to the show. She often misunderstands things people say. D reminds you
of a robot or an android at first, but you eventually learn more about D's personality. Yes, she has one.
