* Arctica's seven knights are called the Fenril Knights. In ''Alter Code F'', it is revealed that, during the original demon invasion, TheDragon to Mother was a demon named Fenril, who was killed by the original Seven Arctican Knights. They literally ''kicked his ass and took his name!''
* Rudy has blue hair. Who else has anime-colored hair? The demons. Rudy is an android that is based on demon biology.
** On the villains' side, Lady Harken has light-brown hair and is much more humanoid-looking than the other Metal Demons. Turns out that she is a brainwashed human.
* "Calamity Jane" is a dual name for both the Jane we see and her sister, who is a lot more experienced than she is. Hence, her relative inexperience compared to her notoriety.
