The last thing anyone expected was for the older twin to manifest Cloud Flames. (Or the one in which Tsuna is Xanxus' Cloud Guardian, flat-out terrifies anyone who's heard about him, has a younger brother who loves him, is possibly in a queerplatonic long-distance relationship with Hibari but will never admit it, and is the big brother you never knew you wanted in your life.)

From the beginning, there was something odd about Namimori. In a world where every city had its own method of dealing with the bane of humanity that were ghouls, Namimori was the first place Reborn had ever been that felt safe to him. People were calm and unafraid on the streets, even after dark. It was remarkable and at first he thought it was due to the fact that Namimori's police force had some sort of foolproof guard against ghouls. But then he noticed the distinct lack of graveyards. By the time Reborn really understood what kept Namimori safe, it was too late to do anything about it. After all, the successor was being tutored, the guardians were chosen, and Xanxus was bearing down on them with half the Vongola rings and all of his wrath. All there was left to do was wait and see.

Omegas are inviting. Warm. The heart of pack life. Tsuna never believed he'd be any of those things. (Omega Tsuna, warm and wonderful but entirely unaware of it, unwittingly draws others to him and inspires unwavering loyalty.) No Mafia. Tsuna's "Family" is just his patchwork pack of similarly damaged children. Lots of platonic pack feels and bonding. Endgame Tsuna/Hibari.

War Sky Tsuna and Home Sky Kyouya declare war on the Vongola.

Tsuna learned young that he was not his parents priority. So he never said anything about the itch under his skin, about the way he sometimes felt his body burn from the inside or how the only time he felt calm was when blood ran like rivulets down his skin. [Or the one where Tsuna finds a family for himself and subsequently starts taking over the world (by accident)]
