Angelic succubus

For ever since he had known her, she had always looked like a madonna and when she was making a speech to defend her ideals with the fervor of a saint, Heero could only see Relena as the icon of peace she was. Yet, he knew very well that she wasn't exactly as pure and angelic as the press described her.

Sure thing, she seemed all innocent, like a cherub with golden hair and big blue eyes, but she also had the iron will and the willpower of the unalterable fanatic who was desperate to achieve her goals. Fortunately, she defended total pacifism, otherwise she could be really dangerous. And in her very own ways, she was.

First, her diplomatic skills didn't need to be proved any longer. By one sermon, she was able to convert even the most unfaithful people to her cause and he had regularly suffered the consequences. But this was not her greatest strength. At least not for him, especially at this moment.
The real talent of Relena was to surprise her opponents by an attack where they least expected her.

Thus, while it should have been him who gave thanks for her hard work and everything she had done in the recent years to ensure peace within the United Nations, she was the one who was kneeling right before him in the kind of position that many normally used to pray.

But if some people adored their god in this way, Relena had was nothing mystical on her mind. Her tongue and lips worked for one purpose, which was by no mean religious or holy. Her only goal was to satisfy her ego by this new demonstration of her power over a man known as invincible.
He had wanted to remind her that she wasn't able to defend herself against everyone and so she decided to turn the argument against him, proving without doubt that he, too, couldn't resist everything.

Unable to stay still any longer, Heero swore inwardly and for a few seconds, he wanted to become a believer, just to pray for his salvation before it was too late. But he was too old to convert and he had right before him the perfect example that even angels can be evil, so why would he bother?
