There would never be anything that could make him give up on her.
No mission too dangerous. No enemy too powerful. A mountain too high to climb, would be reduced to nothing but rubble in his path.
He knew she didn’t need him to protect her. Her power far outstripped his, to the point where the difference couldn’t even be considered humourous. She was a walking nuclear reactor, with the choice to unleash Armageddon and rain the armies of Hell down on any person of her choosing.
He was a sick child, who’d almost met his demise at the hands of a wild monkey. Yet she had never complained about the role he’d subconsciously placed himself into.
He was her light, the beacon that would chase the shadows from her soul. Always there to give her the comfort she would seek, never extinguishing despite any circumstances.
She was his wisdom, keeping him from the trouble that would seek him out, stitching him back together after he was torn apart. She would be the only one that could lift his spirits on the days it would rain in his soul.
They were polar opposites. Light and dark. Heaven and Hell. Sun and Moon.
Yin and Yang.
They would go through Hell and back if that was the price that would have to be paid. Swim through magma, destroy themselves to save the other.
She was the only one that could make him unleash the fury inside. Any threats on his life would allow the evil of her blood to see the light of day.
The unspoken bond they shared was their strength. The love between them was their motivation. The kisses they’d share, with the moon and the darkness as their only witnesses, were what drove them through any obstacle on their path to victory.
In a way, it was almost comical.
Neither would refer to themselves as part of humanity.
But they would rather die than label the other a monster.
My definition of fluff may be slightly different to your definition of fluff. Maybe.
