Tsunayoshi "Tsuna" Sawada is a loser. A really big loser. Last in his class, inept at sports, and generally disliked by the populace of his school.He's also in line to become Boss of the Vongola crime family.Tsuna doesn't believe it at first, but when his 'home tutor', a diminutive hitman named Reborn, arrives and shoots him (apparently) dead, he gains unstoppable determination and becomes able to do a host of amazing feats and command the respect of others... just the sort of thing he needs to turn his life around.However the life of a mafia boss is fraught with danger, and Tsuna and his new 'family' must become stronger if they are to survive the competition.A popular Shonen Jump manga series by Akira Amano (known simply as Reborn! in the Viz translation) with an anime adaptation that ran from 2006 to 2010. The latter is available free and legally with English subtitles at Crunchyroll and Hulu, but only in certain areas.Some interesting fan-works have also been created for this series, most notably the popular roleplay forum, KHR Nuova RPAfter eight years of serialization, the series came to an end in 2012 with a total of 409 chapters.
The Liquidation Committee of Simon Middle School could qualify as well, since they're practically an expy of the Disciplinary Committee.
Abusive Parents: Honestly, both of Tsuna's parents can't really count as being very good parents. His mother, although she loves him, constantly belittles him and cares little about doing anything about his future. His father is a Disappeared Dad who, without asking him about his opinion, decides to force him to become a Mafia crime lord that will be targeted by countless assassins.
His mom only really belittles him in the early chapters. She becomes much more sweet and supportive once Tsuna stops being such a loser.
Action Girl: Lal Mirch. Chrome might get there, someday.
Adaptation Expansion: The "Arcobaleno Trials" and the "Inheritance Succession/Vongola Primo" filler arcs in the anime expanded on the backstories of the titled characters including The Reveal that it was Daemon Spade, Vongola's first mist guardian, who forced Primo to move to Japan, as well as giving Yuni some character development.
The Alcatraz: The impregnable Vendicare Prison. Mukuro and the Kokuyo Gang are the only people to have ever escaped from it, though they got sent back later. The most dangerous criminals are put into a coma and kept chained up in People Jars on the lowest level, where no light or sound can reach them.
All There in the Manual: Want to find out Bianchi's past? How Dino met Squalo? Why Mukuro hasn't taken over Tsuna's body yet despite all the opportunities to do so? The story of the Arcobaleno? Bluebell's Start of Darkness? Well you're going to have to read the novels, listen to CD Dramas, or watch the anime.
Byakuran and his Six Funeral Wreaths all seem to have this too—but in hair colours.
Alternate Universe: Many, in fact. Byakuran and Yuni both have the power to acquire knowledge from multiple AU versions of themselves, which is what makes the former such a Magnificent Bastard.
Ambiguous Gender: Viper, aka Mammon. Goes as a man, but in fact spends most of the time in a form which makes impossible to tell his real gender or even looks. Also continues to live under aliases, to the point even his fellow Arcobalenos Colonnello and Reborn don't know if that's really the person they used to know. When Mammon's looks get finally (partially) revealed, turns out it's suspiciously feminine.
During the Future arc, everyone who is part of the Mafia seem to have this.
A commonly missed fact is that the Simon Family has an insect theme.
Enma is a Japanese rhinoceros beetle.
Aoya Koyo is a dragonfly.
Rauji is a beetle.
Shit-P is a spider.
Adelheid is praying mantis.
Mizuno is a honey bee or wasp.
Julie is an scorpion.
Animation Bump: The fight between Yamamoto and Genkishi had much better animation quality than usual.
Anti-Climax: Compared to Tsuna's battles with Mukuro and Xanxus, the fight with Byakuran is rather short and underwhelming, especially when one considers how much hype Byakuran got before the fight; the power and knowledge of 8-tetra-trillion worlds, and he gets defeated in six chapters by a basic, if Deus ex Machina fueled, X-Burner.
Tsuna's going to the Ninth and refusing to be the Tenth Vongola Boss.
Nearly all of the Vindice except Jager have suffered hard from this trope. They had previously beaten down everyone from the Simon Family to Iemitsu, but when they fought the Vongola, they didn't stand a chance. Some were taken out within the chapter of their introduction. Bermuda, the strongest of the Arcobaleno, lasted two whole chapters before getting beaten down by Tsuna.
Simply admirable evolution of the art in the ENTIRE series. It can't be help that the bishies got even more bishie-y.
Artistic License - Physics: Rampant flame-generation through willpower and Convection Schmonvection aside, Enma is able to create not one, not two, but threeblack holes without utterly destroying well..everything. More recently Bermuda manages to accelerate himself to the speed of light..despite the fact that it'd be impossible for anything with mass to reach that speed without enough energy to remake the universe. Of course this is a shounen manga, but even Dragon Ball didn't take things that far.
Bad Boss: Xanxus, who mercilessly abuses his subordinates (especially Squalo, who is more likely to get heavy objects thrown at him than not) and has anyone who fails to complete a mission killed on the spot. Heck, he even takes out an entire squadron just because they didn't have the right kind of steak he wanted to eat!
Worth to note: In the official Reborn character book, Vongola 77, one of Xanxus's hobbies was listed as: "Torturing Squalo".
To be fair he is a Byakuran from another world who only got mutated because of the transition, which also resulted in the the destruction of his home world. Poor him... right?
Bare Your Midriff: Chrome in her school uniform. Interestingly, it seems to be only her, even though another character is seen wearing a uniform from the same school, and it doesn't bare the midriff. Nor does Chrome's clothing appear to be particularly tight.
ANY GokuHaru fanfiction writer exploits this, having at least 3 "Stupid Woman" in there. As for Canon... well YMMV on that, whether you think the relationship is Romantic or not. It's much more likely it isn't romantic at all.
Beware the Nice Ones: Yamamoto. Hurt his friends, or heck, put a baseball in his hands and he automatically puts on his psycho killer face.
Big Bad: Each arc has its own. Mukuro, Xanxus, Byakuran, Daemon Spade.
Big Bad Ensemble: The Curse of the Rainbow arc. Checker Face and Bermuda Von Vichtenstein, the eighth Arcobaleno.
The Vindice as well. Underneath those cloaks and bandages, the Vindice members look like corpses.
Boobs of Steel: The new transfer student Suzuki Adelheid is the leader of the Simon Middle School Liquidation Committee, an expy of the Disciplinary Committee, who challenged Hibari Kyouya to a duel to determine who will take charge of the discipline in the school. She also has very big... assets.
And they increase in size quite considerably in later chapters.
Book Dumb: Tsuna, Tsuna, Tsuna. In actuality, after the series gets more serious and Tsuna stops being an all-around Butt Monkey, he's shown to actually be pretty darn smart about figuring out how to fight and properly utilize his X-Gloves.
Yamamoto was also initially this, until it's shown that he only makes bad grades because he focuses on baseball instead of classes.
Bowdlerise: It seems that the series' central gimmick, the Dying Will Bullet that momentarily kills Tsuna and then brings him back to life with tremendous power, was a bit too violent for the anime version. So now, instead of Reborn pulling out a gun and shooting Tsuna in the head, Reborn's pet chameleon takes the form of a gun (which is colored bright green, so it looks like a toy) and Reborn fires a bullet from it. The bullet then explodes before reaching its target, leaving behind an energy beam which hits Tsuna. Needless to say, it greatly lessens the impact of the sequence, not to mention coming off as needlessly complicated.
Most other references to Reborn being a hitman or using real guns are cut out as well, probably because of his age. To be fair he is an adult, but you're not supposed to know just by watching an episode or two.
Lal Mirch's scars are changed to a tattoo.
Yamamoto's story on joining Tsuna's family is changed big time. In the manga, Yamamoto attempts to commit suicide, which is foiled by Tsuna, while the anime just has him basically join out of nowhere right after Gokudera.
The anime also never shows any blood, so you see people staggering around like they're mortally wounded when all you can see is a tiny cut or a rip on their clothing. Needless to say, it's quite confusing.
Brother Chuck: Longchamp and his family. He was introduced as the boss of a much goofier rival crime family to Tsuna's, but despite being the focus of several consecutive stories, he proved unpopular, and his whole crew vanished from the series without warning. In fact, the anime removes him from the series all together.
An explanation was presented as bonus material in the 11th collection. The reason Longchamp wasn't in the more action-oriented storylines is because he was taking his Gonk girlfriends out on dates at the time.
Chapter 295 features the triumphant (and brief) return of Longchamp. The entire scene is basically a self-referential joke about how he hasn't appeared in such a long time. He says he's been absent from school a lot lately, and Gokudera claimes to have completely forgotten Longchamp existed.
Lampshaded in one of the mini-comics, where the narration tells us that Lussuria is likely to be quickly forgotten by readers as he is little more than a perverted gay stereotype. He takes great issue with this assessment.
Cerebus Retcon: Reborn being a baby hitman was initially played straight, because the wackiness of the concept fit right in with the comedy feel the series was going for. Once things got more serious, it was revealed that he isn't really a baby at all.
Cerebus Syndrome: *sigh* Wave goodbye to the nice funny now. It won't be coming back.
Chaste Teens: Because the guys from Reborn are not attractive enough to have girlfriends at all.
It's not that they don't attract females—Yamamoto and Gokudera have their share of in-story fangirls—it's just that they're either dense to the popularity or think the girls are as annoying as hell.
Daydream Surprise: Bluebell and Zakuro appear to have the upper hand and seemingly wipe out the Varia. Psyche! It was just an illusion of Mukuro Rokudo's, the real Varia were on the sidelines and, after seeing how Bluebell and Zakuro's powers operate, are ready to take them down.
Debut Queue: And how. Even in the latest chapters, new Bishōnen are still being introduced! ("Let me introduce you to the real six Funeral Wreaths!") And what do we get after the Future arc is finally over? 7new transfer students.
This also happens with Sasagawa, after being bitten in a boxing match, he joins Tsuna's family.
Hibari, who was an enemy of Tsuna in early chapters, could also count. It's not Friendship per se, but since Tsuna's family was able to fight with him, Hibari became a member of Tsuna's family.
Played with a bit with Mukuro and Xanxus, Tsuna's first major opponents after the Genre Shift. Mukuro indirectly becomes one of Tsuna's Guardians (but is still planing to kill him), and Xanxus and the Varia continue to serve the Vongola, but have their own reasons for doing so that have little to nothing to do with friendship—or even loyalty—to Tsuna himself, but rather to the Family.
Also used in the following arcs, Past!Byakuran becomes a good guy after hearing what his future self has done (even helping one of Tsuna's guardians).Enma Kozato also becomes Tsuna's friend after being defeated and finding out that Primo didn't betray his ancestor.
Determinator: The "Dying Will Bullet" headshot grants its target five minutes of pure awesomeness, able to do any one thing they may have regretted in life. Once the time is up, the bullet pops out and they return to normal. And later on the Rebuke Bullet, which is even more powerful than the Dying Will Bullet. Once Tsuna is shot by this bullet he becomes a badass. However, it causes Tsuna severe muscle pain after its used.
Devil in Plain Sight: Reborn and Hibari. No one but Tsuna notices/cares about the horrible things Reborn does, and the police haven't even bothered to acknowledge Hibari yet. But they'll take Haru to the station for waving a fake knife around while wearing some kind of ridiculous monster costume.
Tsuna himself lampshaded this in Episode 15, when Hibari mentioned that he likes to go out on snowy days and throw snowballs at unsuspecting people.
How do you think he controls the school? And the town?
Tsuna:(thinking) "How come he hasn't been arrested yet?"
Devoted To You: Gokudera to Tsuna, Squalo to Xanxus... really, any right-hand man to their mafia boss.
Disappeared Dad: Subverted when Iemitsu comes back and reveals that he'd been working for the Vongola Family all along.
Disney Death: Squalo loses in the Rain Ring Battle against Yamamoto. Yamamoto tries to save him but Squalo's pride doesn't allow him and he gets eaten by the shark that's let loose in the arena. At least, until he comes back to life covered in bandages and guns aimed at his head in a wheelchair at the Sky Ring Battle having been saved by Dino's men and undergone major surgery after the large extent of damage done to him by the shark.
Dojikko: Dino, when he isn't cool (read: when there isn't at least one of his men around him), is really lame.
Tsuna is 10 times as worse, with or without his guardians.
The Dragon: Hibari. A rare example when you think about it, because Tsuna IS going to inherit a mafia family, and Hibari's clearly the second most powerful, if not the first, within the 10th Generation Vongola
Was I the only one that totally thought that Skull was a girl under that helmet? Make-up and all!
Early-Bird Cameo: Irie Shouichi appears in Chapter 13 and is not seen again until Chapter 145 where he's a main part of the arc.
Easily Forgiven: Rokudo Mukuro. Reborn warns Tsuna not to forgive him, but it becomes very obvious that Tsuna doesn't harbor hard feelings toward him.
Elemental Baggage: Tsuna and his "Guardians" are attributed to different types of weather phenomena. Later, it's revealed that everyone has special wave energies that correspond to these seven types.
And the Simon Family has a full seven more original flames. While the flames we've seen thus far are the 'Sky Flames', the Simon Family has 'Earth Flames', with the boss, Enma, presumably having the Earth Flame while his guardians have flames associated with earth. Not only that but Daemon Spade and the Vindice use an 8th element, the Flame of Night.
Filler Arc: Rather special in the case of the Arcobaleno Trials arc since it revealed the long-awaited Canon secrets of the Arcobaleno before the manga did outside the curse itself. May in fact be a case of Adaptation Expansion.
Forgotten Phlebotinum: Tsuna almost activated his Dying Will Mode without a bullet or pill, once (unfortunately, he was interrupted). If the story writers cared to remember that, maybe he wouldn't be utterly useless without Reborn or his DW pills!
Freudian Excuse: Daemon Spade's lover was killed because Primo didn't want the Vongola Family to become too powerful. As a result, he strived for the opposite.
Full Frontal Assault: Ghost walking up in the middle of an all-out-war type battlefield nekkid. He stopped the whole party in three seconds.
Funny Afro: Lambo stores pretty much everything in his hair, even after the series has progressed beyond its gag days. One time he brought home a pair of bird's feet... but no bird.
Future Badass: Most of the characters, but it's especially one of Lambo's gimmicks (also the only character who had a cameo by his studly 20-year-future self). Also subverted by I-Pin, who, while still a talented martial artist, will be a much more benign person in 10 years.
The Future arc applies this trope to almost the entire main cast. Those who were already badass became even more so.
Gadgeteer Genius: Spanner and Future Gianninni but subverted with Gianninni of the present.
Gender Bender: It's not a normal case, but Chrome/Mukuro does this.
Generation Xerox: Perhaps the most over-the-top example of this trope anywhere. Every member of Tsuna's crew corresponds perfectly with a member of Vongola Primo's circle. Tsuna and Giotto are at least blood related, but they look almost identical despite ten generations separating them. The other guardians aren't related to their counterparts, yet they all look and act almost exactly the same, and some even have corresponding life stories. All of which seems to have happened by sheer coincidence.
Odder still is the fact that Tsuna and Giotto resemble each other so strongly, yet the other eight bosses (all of whom would be more closely related to Giotto) don't resemble them at all.
The oddest might be Xanxus' resemblance to Vongola Secondo (including his attitude and Flames), since he's adopted and thus has no POSSIBLE blood relation.
Giotto and Tsuna's relationship has already been cleared up. Giotto (or rather, Sawada Ieyatsu, as he was known after he retired) is Tsuna's ancestor. There is no relation between the first generation and tenth generation, however.
Genre Shift: Starts out as a pure comedy, but after several volumes, becomes a straight-up shounen action series.
Genre Savvy: Many characters seem to realize that they live in a manga world so they don't question the weird things that go on around them.
Dangerously Genre Savvy: Byakuran knows that Mukuro is planning on bodyjacking him any time he could, but he doesn't tell anyone because it's fun to play pretend.
Kikyou when during the Choice Battle, instead of risking his life and the chances of his team's victory in fighting Gokudera, on of the Vongola's strongest members, he uses his plants to seal Gokudera's Box Weapons away leaving him helpless.
Gentleman Snarker: Fran knows how to piss off his sempais just by telling them a couple words of truth.
Godiva Hair: Bluebell. Not that there was something to cover. Also Lal Mirch in one scene.
Gotta Catch Them All: Tsuna having to gather his seven guardians in order to become the Vongola boss. He has to do this twice, the second time being after being sent to future.
Gorn: Recently, Kaoru made Yamamoto a bloody mess.
Gosh Hornet: Episode 12 of the anime has Reborn casually tossing honey on his protégé Tsuna before unleashing a swarm of bees on him. "The mafia always live with danger," Reborn warns Tsuna as the latter runs for his life.
Grand Theft Me: Mukuro's whole plan was to take over Tsuna's body so he could get revenge on the Mafia.
Almost as if in cruel irony, Daemon Spade to Mukuro of all people. Most likely to repeat the past. Oh, and he is currently doing this to Julie.
Frankly there's Engrish all over the place. All the weapon names (if they're not Italian) are in Engrish, and the characters say about two Engrish words per sentence. Granted, many characters are foreign.
Not to mention pretty much all of the opening songs.
"KICK OFF RIDE ON LET'S GO! FLY TO THE SKY! BOYS AND GIRLS BE AMBITIOUS! FUNNY DAY FUNNY FACE FUNNY PLACE! LISTEN TO THE STEREO AROUND AROUND AROUND!"
Not all. The first opening, "Drawing days", had no Gratuitous English. Rather surprising, considering the song's title.
Gratuitous Italian: Though several of the characters are Italian. And Reborn! is about The Mafia. And most (if not all) instances of it seem accurate.
Gratuitous Japanese: For some reason, every mafioso in the series speaks Japanese fluently. In some cases this can be explained (such as with the Varia, who are all required to know at least 7 languages), but not with the Kokuyo Gang, who are just normal extremely dangerous prisoners from Italy. Heck, Rokudo Mukuro, Kakimoto Chikusa, and Joshima Ken are all Italian expats with Japanese names.
Don't forget the Varia's character songs. They're Italian but they sing in Japanese. Also when Squalo and Basil fight in the beginning of the Varia arc. They're both Italian but they converse in Japanese.
The only saving grace is their rather quirky Japanese accents.
Hammerspace: Lambo's hair can fit a full-sized rocket launcher in it while it itself is only about the size of a Soccer ball.
Hannibal Lecture: Byakuran gives Tsuna one, talking about his past experiences as a Butt Monkey. Tsuna retaliates with more fighting, and eventually defeats Byakuran.
Enma and Tsuna get into an argument using Hannibal Lecture. Enma tells Tsuna that he's just like the Primo (whom he claims is a cold heartless bastard) since Tsuna already caused the "death" of three members of his family. Tsuna then shoots back that Enma did that too, and Enma is Not So Different. Enma then wins the speech battle by saying that even though Tsuna claims to not wanting to be the boss of Vongola, he claims that Tsuna is very cunning to plan to take the throne anyways. While Tsuna denies that he wants to be the Tenth, Enma then gives the finishing blow that Tsuna's father and the CEDEF ordered the murder of Enma's family.
Hard Light: Mukuro's, Ken's and Chikusa's illusions when Chrome fights Glo Xinia in the Future arc.
Heel Face Turn: Subverted, sort of, when Mukuro claims he's still after Tsuna('s body). Also, played straight with most of of the cast.
Impossibly Cool Clothes: Suits are always cool and standard crime family fare, but the Varia one-ups the normal family with their leather numbers. See also the reason Mukuro picked Kokuyo as his base, Gokudera's outfit during the Storm Ring Battle, Longchamp.
While most characters choose more practical clothing, others simply live for this trope. Gokudera and Mukuro seem to be the most fashion oriented guardians, what with their liking for leather, belts, chains, studs, Fingerless Gloves, earrings, and various jewelry. Even the bad guys are fond of it: Just look at Byakuran and Daemon Spade.
Improbable Age: Tsuna and several of his classmates and friends are recruited into The Mafia while they are still in middle school. Not to mention, Tsuna is expected become the Tenth...
Instant Expert: Right after they got upgrades on their Vongola Gear, everybody seems to be able to use them perfectly as if they had been with them forever. Don't forget they just got the upgrades in less than a week.
Jerk with a Heart of Gold: Gokudera's The Smart Guy who really loves his boss, plays piano, and subscibes to occult magazines. Mukuro's not a complete sociopathic bastard. Apparently Gamma isn't entirely a bastard, either. Even Xanxus gets a redeeming moment with a heartwarming "families stick together" speech. Perhaps even Byakuran is not so bad after all, since he is revealed to be the one responsible for healing Yamamoto's wounds in Chapter 328.
Just a Kid: In the normal world, at least. In the underworld, infant or child hitmen are commonplace.
Made of Iron: Tsuna. He takes every kind of beating and punishment, and after a good night's rest, is completely unscathed. Not to mention how his body can withstand the amazing heat generated by his Dying Will Flames...
Future Tsuna. Even though it's to save all existence, I'm almost certain that dragging your past counterparts, who are all middle schoolers, ten years into the future to fight guys who are used to fighting differently and more efficiently to jumpstart their growth qualifies.
Good God, Daemon Spade is WORSE than Mukuro.
Byakuran. Who sort of cheats, what with the whole "I can see alternate universes and know what you're going to do" thing.
Fran. How many knives, exactly, has been stabbed into his back and all he said was 'Ouch' in a monotonous tone?
Meaningful Name: "Six Paths Corpse". Wonder who that could be? Also see: The Varia.
Spanner being British-English slang for wrench when he is a technician. Can also be considered as one in the works for being a permanent friend and ally for the Vongola Family during and beyond the Future arc.
Not to mention Yuni who ended up pulling off a Heroic Sacrifice to reset everything.
Mid-Season Upgrade: After Simon's demonstration of My Kung-Fu Is Stronger Than Yours, the Vongola Rings shatter, or break, and everyone's either gone missing or are heavily injured. Then some old guy walks in randomly and fixes the Vongola Rings by upgrading them to the Vongola Gear X Edition.
Tsuna's upgrade: A fancier version of the Vongola Ring that has a chain connected to Natsu's ring. He even got new contacts and headphones from Spanner, of the present time.
Gokudera: A belt buckle.
Ryohei: An arm bangle.
Hibari: A bracelet! Pretty!
Chrome/Murkuro: An earring.
Yamamoto: A necklace.
Lambo: It's a helm. His afro makes it too tight though, so he needs to use the Ten Year Bazooka just to fit in the damn thing.
Mind Rape: The "Vongola Boss Right of Passage", while in a claustrophobic sphere with no light, air, or sound but the ones in your head showing you absolutely horrible crimes, could definitely be considered this.
No Ending: Even though the final arc ends with the curse being lifted from the Arcobaleno there is no clear resolution for Tsuna or the other guardians. Tsuna is still failing his way through school and sports, still hasn't confessed to Kyoko, and is still dependent on Reborn for guidance and all of which is lampshaded mercilessly. He still defiantly opposes being the Vongola boss but offers no alternative for his future. The only difference between the beginning and ending of the manga is that he has friends.
Non-Lethal K.O.: Most of the battles seem to end like this, even when an attack involves grabbing your opponent's head with a flaming hand.
Occult Blue Eyes: According to Gamma, many of the Sky Arcobaleno characters' eyes tend to look as if they expect an event would happen. It's true, since the Sky Arcobaleno have the ability to see the future.
Oedipus Rex: Tsuna's sort-of-love-interest Kyoko bears an incredible resemblance to his mom in both appearance and personality. Iemitsu even seems to lampshade it.
Reversed with Older Haru's crush on Tsuna. She's even got Nana's haircut. Only difference is hair color and those bizarre lines that are ALWAYS on her face.
It doesn't seem like Mukuro chose to show those memories, it seems like they were a product of the illusions plus Tsuna's Hyper Intuition. It's not even obvious whether Mukuro knows Tsuna saw them or not: He acts like he doesn't.
The Pirates Who Don't Do Anything: Considering the majority of the cast are members of The Mafia, you don't see them doing a lot of... mafia stuff. Whatever happened to collecting "rent" from shops or running gambling joints? And cement shoes?
This is justified in the latest arc, where the Ninth boss explains that while the Vongola started out as an outlaw vigilante group, from the Second boss on they began to drift more and more to the side of traditional organized crime. In fact, the whole reason Ninth wants Tsuna to become the next boss is because his crew DOESN'T do mafia stuff, and he wants Tsuna to return the Vongola to how they were at the beginning.
So basically, everyone in the family EXCEPT the main cast is doing Sopranos stuff off-panel, while Tsuna is busy saving the universe.
Playing Against Type: Kiuchi Hidenobu, whose more famous roles include the composed and usually taciturn Hei of Darker than Black and the thoughtful, considerate hero of Dr. Tenma in Monster, plays Sasagawa Ryohei TO THE EXTREME!
The fact that everyone is starting to use the Dying Will Flame is even Lampshadedhere.
Plot Leveling: During the Future arc, the main cast defeated an organization that threatened countless Alternate Universes. While doing that they obtained weapons of Wave Motion Gun levels of power (which are unavailable to anybody else in the present) and now wield the full power of the Cosmic Keystones they possess (of which there are three kinds—one is their own, one is defeated and blocked and the keepers of the rest are their teachers or subordinates of said teachers).
Satellite Love Interest: Kyoko. She hardly has much interactions with Tsuna, and doesn't really have much of a personality. In fact, it's shown in the manga that the main reason Tsuna likes her is because she was the only girl in 12 months who bothered talking to him.
Shaped Like Itself: "Pain is no longer painful to extreme!" and "Painless things aren't painful either!" Ryohei...
Shirtless Scene: For Tsuna, pretty much the first sixty chapters of the manga. Then Gokudera and Tsuna together have one in a forest, trying to dry off.
Ryohei goes topless during his fight against Lussuria. Unfortunately, this only serves to make Lussuria his hardcore fanboy.
The mangaka seems to grab any chance she can to get Xanxus' shirt off.
Yamamoto got one in the anime, which verged on Shower Scene. With more Fanservice of the gratuitous Ho Yay sort, as Gokudera (again) comes in the changing room and starts taking off his shoes while sitting in front of a standing, still shirtless Yamamoto.
To be fair, it is a part of Japanese culture for men and women to go to baths together, so it is not unlikely that the two of them would end up showering at the same time. The same thing is true for sports teams in various other cultures as well.
In the OVA there's a fight between the Varia and the Vongola, inside an onsen which is obviously one big and fanservicey shirtless scene for everyone, incluiding Hibari!
Chapter 372 gives us Fon's turn at a shirtless scene. In his adult form, of course.
Sink or Swim Mentor: Pretty much every single mentor Tsuna has had? Reborn, Lal Mirch, TYL Hibari...
Future Squalo to Yamamoto.
Doctor Shamal to Gokudera. He even refuses the heal his wounds. (Although he does care; he just knows it won't do any good).
Slasher Smile: Bel, all the way. Also, his even more psychotic twin, Siel/Jill/Rasiel/whatever. Both seem to have this smile on permanetly. Except Rasiel's looks like a rictus from Hell. "Ushishishi!" "Ushesheshe!"
Sorry I'm Late: Yamamoto and Hibari, though Hibari wasn't sorry, when they came microseconds from being late to the Choice Battle.
Also, Gokudera to the Storm Ring Battle.
And Yamamoto once again in the Inheritance Ceremony arc.
So Last Season: Despite the series' biggest gimmick at first, the Dying Will Bullet, is pretty much retired after Tsuna gains the Rebuke Pills.
The Spartan Way: Reborn, Colonnello, and Lal Mirch all love to beat up their students.
Tsuna even lampshades this with Colonnello and Reborn: "He's even more Spartan than Reborn..!" (gets beat up).
Spell My Name with an S: So is it Chiavarone or Cavallone? Also, Marmon/Mammon, Lussuria/Lissuria, Colonello/Colonnello, Mosca/Moska, Lambo/Rambo etc. Also, Jill/Sil/Siel/Rasiel/that guy.
Most of these can be resolved with a decent knowledge of Italian language. It's Lussuria (="lust"), Colonnello (="colonel"), Mosca (=the insect called "fly"). As for Chiavarone (which is a real-life Italian surname, Google confirms it) / Cavallone (=more or less "big horse" ,though it's a rather colloquial term), they both are valid Italian words so I'm not sure about this. Also, while not an Italian word, I'm pretty sure it's supposed to be Mammon, which is the name of the demon of Greed (following the Seven Sins naming motif the Varia seem to use).
Spit Take: Both Tsuna and Yamamoto do one at the same time when Lambo comes in and tells them that, "Right now, in the shower... THERE'S A LOT OF BOOBIES!!"
Spoiler Opening: Mukuro's Heel Face Turn and Chrome's existence in the second opening, Ryohei's Box Animal before it was even introduced in the manga in the fourth.
For the non-manga readers, the X-Gloves in the first opening, the existence of the non-sky Vongola Boxes, the Vongola Box Animals, and five of the six Real Funeral Wreathes in the seventh opening.
In the eighth opening, Byakuran's final form.
Stalker with a Crush: Gokudera to Tsuna. He becomes unreasonably jealous of anyone who is close to Tsuna, and is even shown watching Tsuna and getting incredibly pissed at Yamamoto for being so friendly with him. Not to mention his violent reaction when Chrome kisses Tsuna.
Haru could be considered one at her very first appearances, from when she liked Reborn.
Theme Naming: The Varia are named after the Seven Deadly Sins or their associated demons, and the Millefiore family is largely named after flowers. A sizable amount of the casts' names reference Italian or European vehicles.
Some of the members of CEDEF (ex. Basil, Oregano) Even Lal Mirch who's name means "Red Pepper."
Parts of the Simon Family's names have Earth-related words in them when translated.
This Cannot Be!: Xanxus isn't too happy about the fact that he's clearly getting beaten towards the end of his fight with Tsuna.
Xanxus: "Not possible! This is impossible!"
This Is Unforgivable: The anime is so good at this. Poor Yuni's gone from this world, and Byakuran's complaining about how she was a toy, and his plans were ruined...
Tsuna: "Why do you think Yuni had to do this...? You ruined our world. That's why Yuni... That's why Yuni DIED!! Byakuran! I... I WON'T FORGIVE YOU!!!" Cue Tsuna curbstomping to the point he kills Byakuran. That's right, present Tsunakilled Byakuran!
Threesome Subtext: Neither Gokudera nor Yamamoto is shown to have any potential romantic partner out of the rest of the cast, yet they're both awfully close with their Boss.
Lal Mirch qualifies too, at least towards Colonnello.
Übermensch: Hibari, though he prefers to limit his ubermensch-ing to his beloved small town.
Uke: Tsuna may very well be the poster boy for this trope.
Uncanny Family Resemblance: Tsuna to his ancestor Vongola Primo. Another example that makes a lot less sense is Xanxus to Vongola Secondo, considering that he isn't even supposed to be related or have any real Vongola blood in him. Are they really sure he isn't the Ninth's secret love child?
Also Yuni, Aria and Luche.
And Hibari to the first Cloud Guardian, Yamamoto to the first Rain Guardian, Mukuro to the first Mist Guardian (who was a traitor to the Family), Gokudera to the first Storm Guardian... You get the picture.
And Hibari to Arcobaleno Fon, to the point where I-Pin's crush on Hibari comes from his resemblance to him. The reason is never explained.
Actually, in a Haru Haru Interview in the Manga it is revealed that Hibari and Fon are related. Which also explains why Hibari became Fon's representative during the The Curse of the Rainbow arc.
It turns out that Tsuna didn't kill present Byakuran after all. He just has his multiverse-awareness powers removed.
Squalo does this twice, first when he's eaten by a shark in the Rain Ring Battle, then later shows up at Xanxus and Tsuna's battle (after having been rescued by Dino's men and undergone major surgery) seemingly just fine, aside from being bandaged and in a wheelchair and the second time when he's seemingly killed by Zakuro; his cyborg hand is the only body part left when Yamamoto goes back to look for him. Turns out that he's still alive when he comes limping in to the final battle once again supported by Dino, and then he seems to be completely healed by the next day. Indestructible much?
And now Yamamoto does this as well when he shows up in Chapter 325, pulling off one of the best Big Damn Heroes moments in the series.
How exactly did Xanxus manage to regrow the arm he lost in the fight with Jager?
The Un Reveal: Reborn finally gets nailed by the Ten-Year Bazooka... but no Adult!Reborn. Still 68 more episodes to go if you're watching the anime.
Up to Eleven: Tsuna's taking his act up a notch when Yamamoto nearly gets chopped in half by a "mysterious" person.
Verbal Tic: Colonnello, kora! Although sadly, taken out in the Viz Media translations.
Haru has a tendency to say "hahi!" when surprised.
Ken also tends to end his sentences with "pyon!"
The loudest mafia member has one. Goes something like this: "VOOOOOOOOOOOOOOOOOOOI!" Remember him?
Lambo likes to add 'monya' or 'damone' to the end of his sentences.
Villainous Breakdown: While normally calm and polite, Byakuran finally loses his cool after Yuni's Heroic Sacrifice, complaining that Yuni was a toy and that without her, his plans are ruined, all because of her key importance in his plans to become ruler of all time and space.
Vocal Evolution: Just watch any early episodes and see how much they have changed. Special mention goes to Tsuna, Gokudera, and I-Pin.
Winged Humanoid: Invoked by Byakuran. Definitely some major God-complex going on; heck, there's even a fanmade character song for him titled "God Complex"...
The Worf Effect: Basil, a supposedly elite member of CEDEF, is the only person other than Tsuna (and Primo) to fight in Hyper Dying Will Mode, but he's lost every battle that he's been in.
Up until now, Gokudera has only really won ONE fight in the entire series. Granted, one of his losses was intentional, one was a tie, and the other was due to an interruption, but he still loses a lot.
Yamamoto too, in that with the exception of Ken, he's never beaten someone who hadn't previously kicked the everloving crap out of him with increasingly painful results. Squalo did a bit of physical damage and hurt his pride, Genkishi made him run into a wall and knocked him out, and now Kaoru blew his insides all over a locker room and may have crippled him for life. The only reason he ever manages to beat these guys is cus of his Charles Atlas Super Power, though the last one is subverted as of Chapter 325.
Out of the three main arcs he has been in Squalo has been presumed dead in every one of them, always to show how evil (Xanxus) or strong (Zakuro, Jager) the enemy really is.
World-Healing Wave: An extreme case, since the Arcobaleno don't just restore one world magically; they need to fix every parallel world in existence after Byakuran utterly destroys all of them, aside from the one he's finally defeated in.
Yakuza: Not Tsuna's family, but when Dino wants to 'test' Tsuna's family, he fakes a kidnapping and tells Gokudera and Yamamoto he has been kidnapped by the yakuza. It was supposed to be a fake yakuza but of course Reborn just had to go to extremes.
Yandere: Lethal Chef Bianchi goes into a homicidal rage whenever she sees adult Lambo, who looks exactly like her deceased ex-boyfriend Romeo (who apparently died of food poisoning). Make of this what you will...
