I don't own Katekyō Hitman Reborn!.

Brothers and Sisters

"It is very quiet without Tempesta around, is it not?"

Sereno purses his lips in wry amusement. "You want me to lighten up the place?"

Nebbia blinks, unfazed. "You really went out of your way to prepare that pun. I am thoroughly ashamed to call you my brother."

He laughs and rubs the back of his soft hair. Then he perks up and raises a finger in question like an obedient pupil. Nebbia looks for an escape route but she's alone in this. Cielo has wandered off to comfort a depressed Fulmine. Something about being in the possession of a very large, very mean looking man with umbrellas who keeps rambling on about an even meaner man with very red eyes.

Yes, he's the first one to lose a battle. Not that the Spirits can technically lose, Nebbia has tried her best to explain that to him, but he's lost the chance at being at the real Lightning Guardian's side.

Now he's hurling thunderbolts in some far-off corner of their world.

Seeing as Sereno is still waiting on her, the Spirit of Mist sighs and crosses her legs on the conjured veranda. "What is it?"

"How come I'm your brother?"

Nebbia blinks. "You've had centuries to ponder the question and you ask me now?"

"Yes!"

"Idiot."

"Hey!"

Nebbia rubs her eyes. She can feel a storm brewing at the back of her mind and this time it's not a fake one. Tempesta, true to her nature, cannot hold herself back. Nor does she want to. This reminds her of something. "I think it actually started with that woman."

Sereno inches closer to her, doing little bunny-hops as he does so. Nothing can bring his mood down. "She was constantly fighting with both Fulmine and Pioggia for an imaginary throne. One day she started blurting out that she was the eldest among the three and that she should win by default."

"Why?"

"Because rain and lightning usually accompany a storm. Therefore she has to come first."

"That means Cielo is the eldest of us, right? Is that the reason she doesn't fight him?"

Expression ever a blank one, Nebbia nods. "It would be counterproductive to destroy the one element that encompasses you as you are. Besides, the fighting was partially about gaining the position of being Cielo's right hand."

"I see! And then the rest of us just picked it up."

"Actually, it was you who said that it would be beneficial to our relationship."

His mouth makes a perfect circle. "I did? Oh, that's awesome of me!" He pauses and Nebbia takes the time to wonder how much heat he must produce to fry his own brain cells. How could he forget just like that? "Wait a second. What about Nuvola? Tempesta is always trying to throw her out..."

They turn around to glance at the sleeping form of their last so-called sibling: the Spirit of Cloud. All there is visible of the woman is a tuft of cotton candy hair. The rest of her body is curled up like a hedgehog.

Even the fearless Nebbia crawls a step back. "Let's just say that waking someone from their vacation on cloud nine hasn't been one of her greatest ideas. Nuvola chewed her up before she could so much as draw a storm." She clears her throat. "A one-sided rivalry was born. Nuvola now holds the spot of right hand by Tempesta's own rules."

"That's why she's so angry..."

"It is a horrible symbiosis, indeed."

A/N:

Just imagine Ryohei and Mukuro sitting down somewhere, talking. Because I can't. Hell would (literally) break lose if they managed to exchange even one coherent sentence. And if we were to add a sleeping Hibari into the fray...
