1 being that as he approaches high school, he starts shifting his stance on never accepting this mafia boss bullshit, but not because he is suddenly shifting his moral stances or anything
He doesn't want him or his friends to get involved in this horrifying world where they could die or be seriously injured. Tsuna votes that all of that is bullshit, and he would rather not, thank you
But as the years start slowly adding up, he realizes that... There's no way he's not involved, now. Hell, he was always involved, because even if his dad didn't tell him anything
His declaration during the Vongola Trial that he'd destroy the Vongola before continuing its history of pointless bloodshed? Still holds true. But he's willing to try and change the Family before getting to
Sometimes they're spurred on by something- another attack on him or his friends for example will bring out heavy bloody-and-misery memories when he sleeps
Other times there's no real trigger for them, and those times can sometimes be the general Vongola nightmares, but, over time, he starts getting flashbacks from Giotto's time
Which mix with his own memories sometimes and make him very disoriented when he wakes up (which can be in the middle of the night or in the morning depending)
This sometimes culminates in him needing to be with one of his guardians and slowly separating Giotto's memories from his own by studying their features and them helping him through it
Chrome is actually the best person for this job, both because of Mist's connection to weird bullshit and because of the fact that none of Giotto's guardians were women
By the time Tsuna takes on the title of Vongola Decimo proper, Vongola, Simon, Giglio Nero, and Cavallone all already have a strong connection and alliance through the tenth generatio n
and this basically starts out during Tsuna's school years, when he introduces Dino to Enma and Adelheid (who benefit greatly from being able to work with someone who has a familiarity with dragging his Family
Anyway, Tsuna starts getting lessons in Italian, spurred on half by Reborn's spartan training methods and half by the fact that Kyoko saw him studying it once and complimented him
By the time he gets to high school, he is basically proficient (by Reborn standards) in Italian and also has enough of a spine to finally ask Kyoko out
It's more to do with the way he holds himself and starts interacting with people, which helps that he doesn't avoid school like the plague or else he'd get worse than plague, which is Reborn kicking his ass
So under the Vongola Community Club, he starts practicing and figuring out this whole thing (which is probably the route Reborn was aiming for him to go down)
Tsuna starts leveling up his charisma, although he doesn't really put that description to what he's doing, and he starts getting much better at figuring out people
For example- oh, Akio is good at keeping track of where to buy fashion and trends, they obviously have a good eye and intuition towards commerce, and Hideki is good with numbers
"Oh, I told Sawada that I'd help him out with the schedule for his club. He's so helpless, I couldn't say no. He needs my help, you know?" and things like that
Along with getting a handle on English from school and Italian from Reborn, Tsuna also starts learning scattered bits of Chinese from I-Pin (because he loves his little sister) and is made to start learning
For the first year of having this knowledge, Tsuna doesn't know how to react to the fact that it is very easy for him to take on a more femme appearance
during which they have a long and private conversation about a variety of things, including Tsuna's goals after school (which he offers to tell her more about, but Nana tells him it's alright not to)
(something which can't be said for his relationship with his father- Tsuna has thought about it, and Iemitsu still tries, but there's still this kind of chasm between them)
She accepts, and they become engaged but don't become married until a few years later because Tsuna wants to make sure he makes the Vongola good/safe enough for her
(he is in love with so many of his friends and it is kind of glaringly obvious except people think they're mistaken when they see him gush about Kyoko)
(because?? isn't it totally normal??? to think about how attractive your friends are???? and how you feel so cared for and happy around them???? and hope you stay with them forever?????)
Tsuna and Co graduate high school, with some (Ryohei and Hibari) having done so a year prior, and are immediately shifted to Italy so that Tsuna can take over already
but Tsuna is still this 18 year old who is a foreigner. He's nothing even remotely similar to the previous would-be heirs who are now all currently dead
However, his general method back in high school won't really work in the way it was set up, because those were normal teenagers and these are all a bunch of adult criminals
And, from all that experience, he knows that if someone thinks you're weak and pathetic and inconsequential enough.... They'll talk shit right to your face as if you aren't there
And, together, him and Chrome keep track of who is: shittalking to his face, shittalking but out of hearing, the few actively trying to help him out, and those who are watching and waiting
(Yuni has problems trying not to giggle, Dino and Enma quietly amused, and Adelheid looking absolutely Fucking Done with the other mafia because really, you're gonna be this thick)
Towards the latter half of the party is when Tsuna goes up to make a speech and, in perfectly flawless Italian, basically drags everyone who was enough of a jackass to shittalk
And then, at the end, Tsuna says "While it can't be explained just how rude and hurtful it was to hear that you so easily display a low opinion of the Vongola..."
if "I forgive you" after a speech like that didn't sound suspiciously sound like "I am going to cut off your knees at the caps and this smile means I'm going to enjoy it"
(it's just that him and Chrome take vicious delight in being underestimated and watching people's faces drop when they realize they are tiny and cute and some of the strongest in the whole group)
For the others who shittalked, they tend to be the ones sending gifts or other such things because they're pretty sure they Fucked Up and are trying to negate any damage
So yeah, that's the kind of boss Tsuna ends up growing into- one who doesn't like to use outright force to rule, but instead relies on charisma and cunning, especially of the social sort
Chrome: -laughing- How many times has one of us caved when you frown? How many times have you caved when Reborn pulls out his gun? You know he won't shoot you.
As a general rule, I go with his relationships being: familial - Reborn, Dino, Ryohei, Enma, Fuuta, I-Pin, Lambo romantic - Kyoko, Gokudera, Yamamoto, Chrome, Hibari, Xanxus
Since I totally spaced on doing it yesterday, whups, but yes, my TYL Tsuna headcanon compilation plurk
