Breathing is a rather novel experience for her.
Before, she'd been a normal spirit – well, one of the two most powerful spirits known to the world, but you get the idea – and like any other spirit, hadn't needed oxygen to survive.
She had known, somewhere in the back of her mind, that normal creatures – humans, animals, and insects – needed to breathe, but she'd never really acknowledged it until she and Wan became one.
The quiet puff of air in between inhales; the feeling of his muscles expanding and contracting to intake air; the pump of his heart sending fresh blood to every vein within his body. At first, she'd considered the sensations unnatural and slightly unnerving to the point of shying away from it as much as was possible when they literally shared a body; now, she can't help but revel in it.
Breathing means Wan is alive, and that he will continue to be so for the time being.
And if she has to rip armies apart to keep him that way, then so be it.
No matter how old he might get, how grey his hair is and wrinkled his face becomes, he is still the precious boy she'd teamed up with to save the world from one terrible mistake, and she wasn't letting that naïve young man go without a hell of a fight.
Because she knows their time together is limited. And she's not letting a single second slip away.
A/N: Raava is the most badass character on Legend of Korra aside from Kuvira. And that's saying something.
