Reborn!

Tsuna Sawada, who is bad at pretty much everything, is assigned a strange tutor: a baby wearing a suit who claims to be a hitman named Reborn.

Thanks to the deathperation shot, a special Vongola Family bullet, Tsuna wins his match against Mochida and is able to talk to Kyoko.

Two strangers arrive in town searching for Tsuna's house; meanwhile, Tsuna has become friends with Yamamoto and Gokudera.

Haru Miura is a girl who has been secretly watching Reborn ever since she fell in love with him at first sight; she finally makes her move, but when she talks with Reborn, she gets the impression from his words that Tsuna is a bad influence on him.

The Disciplinary Committee has immense power in the school that Tsuna attends; school council leader and head Disciplinary Committee member Kyoya Hibari is the leader of the delinquents, and mercilessly attacks anyone who is weak.

Tsuna is saved by I-Pin, a small child wearing Chinese clothes whose techniques can only be described as psychic powers.

Reborn shoots Tsuna with a deathperation shot in the morning and Tsuna goes to school in deathperation mode.

Tsuna returns home only to find a black car and a bunch of frightening faces waiting for him; thinking it's Reborn's doing, Tsuna rushes to his room and finds a young man waiting for him.

Tsuna suddenly becomes dizzy, and a skull mark appears on his hand; according to Reborn, it is the symptom of an incurable illness known as Skullitis.

Tsuna forgets his lunch at his house and Lambo ends up taking it to him; when Lambo bumps into I-Pin, who is carrying nitroglycerine to her master, a mix-up of packages results in a riot at school.

When Tsuna meets Haru in town, and the two of them then bump into Kyoko, Reborn invites the girls to come home with Tsuna.

Gokudera is embarrassed when he is unable to protect Tsuna from bees, and Reborn suggests he try the Vongola Strengthening Program.

Reborn declares that the customary Vongola New Year Inter-family Battle will be held with Dino's Chiavarone Family as their opponents.

Reborn has set up Tsuna on a date with Kyoko; Tsuna is thrilled, but when he meets Kyoko at the zoo he can't seem to avoid running into people he knows.

Reborn separates Tsuna and his friends into two teams and pits them against each other in a snowball fight.

Dino, Gokudera, and Yamamoto go to an unexplored area where Tsuna is supposed to be training with Reborn.

Tsuna is hospitalized because of his injuries from Death Mountain, but his peaceful recovery is continually interrupted by his noisy friends.

It's Valentine's Day, and Tsuna is curious to see who Kyoko will give chocolate to, but he lacks the courage to ask her.

Tsuna meets a boy named Futa, who is being chased by Mafioso for his ranking book, which is said to have 100% accurate ratings.

A sudden series of attacks have targeted Namimori Middle School's prefects; according to Ryohei, Kokuyo Middle School students are behind it.

Reborn has discovered that the perpetrators behind the attacks on Namimori Middle School are not ordinary students, but people involved with the mafia.

Yamamoto narrowly wins in battle against Ken Joshima, but Tsuna regrets the fact that he was a burden, as when Gokudera got injured protecting him.

Gokudera and the others have been separated from Tsuna, and the main perpetrator of the attacks, Mukuro Rokudo, appears before them.

It turns out that Mukuro is really Lancia, one of Mukuro's associates; with an injured Yamamoto still unconscious, Tsuna and the rest of the gang charge after Lancia.

It appears as if Hibari has put an end to the battle, but things start to look different when Mukuro shoots himself with a gun.

In response to Tsuna's desire to defeat Mukuro, Reborn creates new items: the Criticism Shot and the X Gloves.

Tsuna is eager to find out whether he's going to be in the same class as Kyoko again, but Tsuna ends up in Group A and Kyoko in Group B.

Kyoko is coming over to Tsuna's house for a visit, and Tsuna cheerfully begins cleaning his room for the event.

Hana Kurokawa considers the boys in her grade to be monkeys, but amazingly falls in love with Adult Lambo and asks Tsuna to introduce him to her.

Nana wins a magazine prize for a trip to a southern paradise on a luxurious cruise ship; with Reborn and Bianchi staying at home to look after Lambo and the others, an elated Nana and Tsuna are on their way.

What started as a tropical cruise takes a turn for the strange as the group lands in a resort island called Mafia Land.

Yamamoto, Reborn, Haru and Gokudera try to teach Tsuna how to swim, and it soon becomes a competition.

Tsuna has taken on a summer job to pay off a debt caused by Lambo, but at his beach workplace he encounters some unsavory high school students who turn out to be his superiors.

Tsuna's school trip takes a Vongola twist, turning relaxation into unexpected challenges and encounters.
