(Borrowed from mukurou69 . Also, because mun was bored. >_>)

This Hibari here is married to a Mukuro – specifically,mukurou69 . The latter proposed in December last year, and to Mukuro’s surprise, Hibari had accepted. They are now living together, quite happily married (or as happily as those two can ever be). They have adopted a child by the name of ‘Kyo’ (who is, in fact, a cuter, younger version of Hibari), and Mukuro is also carrying their first child, thanks to a Daemon Spade who gave him the required organs  freely, and for as long as they were needed.

His world is like a Nexus of sorts – he has met various versions of himself, along with other versions of people he knows (for example, Mukuro’s self-proclaimed father there is a Daemon Spade). Anonymous figures randomly visit and cast spells on him, resulting in a multitude of effects – amongst others, he has been turned into a vampire, been genderswitched several times, been turned into a cat, and had several fandom crossovers with Durarara and Kuroshitsuji (in which he was Shizuo and a Lord, respectively.)
Hibari has the Vongola Gear, knows about the Shimon incidents, and Daemon Spade – incidentally, one Daemon Spade saw fit to possess Mukuro just before the wedding, and so it was very nearly called off. But through the collective efforts of Hibari’s own self-proclaimed father (an Alaude), Mukuro’s ‘father’, and Hibari himself, they were able to free him from the possession.

Hibari has mellowed out somewhat – he is less likely to be able to be provoked into a fight, though Mukuro may claim otherwise. Despite this, he still can be rather violent if he wishes to, especially towards anons and such.

Other relationships

Gokudera: He still refers to Gokudera as ‘Sawada’s dog’, though their relationship is somewhat more stable than when it was ten years ago.

Yamamoto: He’s still interested in sparring with Yamamoto, though he has fought with a younger version of the Rain Guardian before, and thought it quite satisfying. He hopes to be able to spar with him once more, when the other will be able to use his Vongola Gear.

Tsuna: He refers to the Vongola boss as ‘Sawada’, and still refuses to acknowledge the fact that Tsuna is his boss – rather, he views the Vongola as an ally at best, viewing the Foundation and the Vongola as separate entities. The alliance between the two organizations is one of convenience – once Hibari thinks that he no longer needs anything that the Vongola can provide, he will cut off the alliance. He does, however, have a grudging respect for the man that Tsuna has become.

Dino: The Cavallone don is one of the people that, to Hibari, have never changed, even after the ten years since he first met the older man – he is still as annoying as ever. Hibari will tolerate his presence, though he is not above smacking the don down with a tonfa if he is feeling particularly annoyed with him.

Kusakabe: The vice-president of the Disciplinary Committee from ten years ago has gone from that post to being his second-in-command of the Foundation – he is the closest thing to a ‘friend’ that Hibari has. Other than that, their relationship is purely work-driven.

Other Important Details:
He can use both his Mist Flames and Cloud Flames equally well, the former due to some help from Mukuro, the latter through his own hard work. He once had Sky flames as well, due to a godly anon, though they disappeared after two weeks.
