[Reborn!] Who Sends a Letter from the Clouds?

Even to the Vongola family, feared throughout the underworld, Hibari Kyoya was an extremely mysterious person.

His age, birthplace, parents, and family were all unknown. Even the name "Hibari Kyoya" they knew so well might have been fake. The only two things they could be certain of were his gender and his naturally handsome, unaltered face.

At first, there were plenty of voices in the Vongola family asking, "How can someone whose origins are unknown hold such an important position as Cloud Guardian?" Yet the mysterious man continued to bear the title of Cloud Guardian, coming and going at headquarters like the wind, entirely unconcerned by what others thought.

The all-embracing Sky smiled and told everyone, "I will always believe in my guardians."

1. This is a hypothetical scenario where "the ones with 18's face all have the surname Zhang" (yes, that Zhang).

2. There are tons of original details. JJ and DM left too many plot points unresolved, so I'm making things up based on the timeline I've worked out myself.

3. Pairing: 2718. When 27 was nine years old, he gained the memories of a version of himself who had been shot by Zhengyi as part of a ruse, and had never experienced the Future Arc. In those memories, when 270 started the Ten-Year Plan, 18 was no longer with the Vongola for some reason. This isn't rebirth. It's more like dreaming about the next fifteen years of his life ahead of time, plus a double dose of combat experience.

4. The world's will = the Ultimate; 7? is something inside the door.
