Summary: Hatake Kakashi becomes Hibari Kyoya's older sister. The world breaks and the original future goes down the drain. A Naruto and Katekyo Hitman Reborn crossover story. AU. Drabbles. Short chapters.

Disclaimer: Naruto and Katekyo Hitman Reborn are not mine.

Note: Tsuna's characterization's based on my own perspective. He's a tad...saucier in this one. Cough.

PART i: Tsuna's internal diary that he kept from the world - Hibari Kei special.

1.

Sawada Tsunayoshi could distinctly remember the first time he met Hibari Kei.

It was etched into his mind, straight into his bones, blood, soul-

(And no, it wasn't because Kei was pretty.)

(...Which she was, Tsuna could admit that to himself-)

(When he's alone.)

(And in a bunker somewhere.)

(Definitely not with Reborn in sight, no.)

(Kami, no.)

(The thought of Reborn's antics and penchant for chaos with Kei's trolling and Hibari's...cough cough low-key-but-it's-really-not sister complex was too fudging terrifying, Tsuna honest to Kami swear he almost peed his pants just as he was subconsciously thinking this.)

(Although he knew Reborn's pseudo-mind reading skill was just him being a bastard, Tsuna knew from experience that it was better to be safe than sorry.)

He couldn't help it.

It was too strange, too baffling, too memorable that he couldn't un-remember even if he wanted to.

Yes.

It was un-remember.

Which Tsuna knew wasn't a word, shut up. He was having his moment here.
