A compilation of my adult Gen 10 Vongola Guardians headcanons of all time:
Tsuna does become the Vongola boss. He does it with the purpose of being the last one, tho.
Tsuna got Mukuro to go along with his plans by promising Mukuro would be the one to kill him one day. He was dead serious about it.
Reborn hates Mukuro's guts and thinks Tsuna is a fool for trusting him. Mukuro knows that Tsuna was serious, so he follows his lead, as long as their deal stands. Tsuna plans to let Mukuro kill him when he's an older man and burn his own body to the ground with flames, so Mukuro can't possess him.
The older they get, the more rebellious the guardians grow towards Reborn. They start maturing and following more Tsuna per se, his ideals, his plans.
Gokudera in particular has a very (!!) tense relationship with Reborn. With age, Gokudera stops idolizing Reborn and engages more and more in open arguments in Tsuna's behalf.
At least once Yamamoto pointed his blade at Reborn seriously. Solving that situation was a nightmare.
Most of them go to university or get a minor degree as Tsuna's requirement to "join" the family. Tsuna might hate studying, but he does not fuck around about getting proper education for all of them.
He hates the Vongola mansion. He buys the ruined property of a poor family for an tbh exaggerate sum and makes them build a proper complex there. It's close enough to the Vongola mansion that he can walk (fly?) to it, so he has all his official meetings there and reserves the complex for the informal reunions with friends and family.
Dino and Tsuna had one (1) major fight. It was about the expectations on Tsuna, the reality of the mafia world and the of course, Reborn. They agreed to go all in only once and then never fight again. Dino promised that if Tsuna was the last of the Vongolas, he'd be the last of the Cavallones. Tsuna promises to give a chance to the mafia world and see what they could make out of it together.
Fuuta, I-Pin and Lambo graduated from middle school in Namimori. Bianchi stayed with them during those years and everyone would visit them regularly.
In that time Lambo realized he'd miss Tsuna too much, so be begged Tsuna to let him go to a high school in Italy, closer to him. They all ended up studying there.
Kyoko stayed in Japan with the kids at first and started studying there. She missed her brother a lot, tho. Haru went to a different university. She was brilliant, but after the adventures with the guardians, common life was a bit boring. They ended up moving to Italy to finish their studies, which means even more shenanigans of Tsuna trying to cover the mafia life and the fact he's rich now.
Yamamoto went pro for a few years. First in Japan, then some seasons in the US. He got an insane network connection lol. He then made an excuse about salary to move to Italy to "play there". The Vongolas own the team as an effort to get kids from poverty into a proper lifestyle.
Part of the Vongola income now comes from sports bets. Nothing illegal. In fact, Ryohei scouts impressive athletes and checks to see if other mafias are interfering in the match. Some athletes and organizations actually pay them to check and eliminate any cheating agents.
They send Hibari lmao. He hates weak people and no one is weaker than those who need to cheat in order to win.
Gokudera unironically takes into cooking and decoration. Is he a malewife? Sort of. If you were Tsuna's right hand man, forced to watch him through the tightest schedule ever while he tries to solve at least 9 generations of Vongola mistakes... He personally prepares the food to guarantee they are not poisoned and arranges most rooms so there's always at least one seat Tsuna can comfortably nap in.
The next trip to Mafialandia is even worse. Either Tsuna is treated like a celebrity so he has not a moment of peace or Reborn sends him on another training.
Tsuna is a champ in human relationships.
The complex is rarely quiet or empty. At the same time, the guardians aren't all reunited as often. They make sure that Tsuna doesn't feel alone and create excuses to show Tsuna the progress of all his effort.
Omg I didn't plan for this to be such a long post. I'd have to do a series at this point 😂😂
