Ah, the trusty Devil.  Technically the "Devil" here is represented by the Epyon (see Symbols).  This card, like any of the others, is open to lots of interpretations.

"This card lets you know that you are caught in an unhealthy, unproductive situation. You may be in the dark about something - ignorant of the truth and its implications. You may be obsessed by a person, idea, substance or pattern that you know is bad for you (or maybe you don't!). Sometimes this card reflects back the negativity that has made you doubt yourself and your future."

With regards to Bunning's key, I think this sounds a lot like Relena's situation during the whole White Fang shebang.  The "foreseeing a bleak future" line, however, reminds me of what Heero said about Milliard: "Zero tells me that you don't have a future.  I wonder what Epyon is telling you?"  So, in an obscure way, this card could also represent Milliard's struggle to find a cause after the destruction of the Tallgeese.

Other readings of the Devil include violence, strength and extraordinary effort...sounds like Heero in the last episode, eh?

Symbols:

- the Devil -- it's interesting that the Epyon is moved to the background in this image.  It certainly has a devilish appearance.  But unless the Epyon represents Milliard Peacecraft as the true Devil, the focus of this card has become Relena and Heero and their problems.

- the chains -- these represent enslavement, whether to another person, or to a cause or ideal.  These were done, interestingly, as strings in the Gundam card.

- the lovers -- these make the Devil card into a kind of parody of the Lovers card; the Devil represents the physical while the Lovers represents the spiritual.
