Character Outline
Kyoya Hibari (雲雀 恭弥, Hibari Kyōya) is the leader of the Namimori Middle Discipline Committee, a group of delinquents who all are loyal to Hibari. He is a violent delinquent who uses his status to harass other students. As shown several times in the series, he prefers to be alone and cares little for his subordinates. He loves Namimori more than anything and will often say "I'll bite you to death," or "kamikorosu," to those that disturb Namimori Middle School. Hibari is very proud of his school and is apparently the only person who likes their school's anthem, even using it as his ringtone. In the Kokuyo Arc, he adopted one of the Kokuyo assassins, Birds' bird. The bird (subsequently nicknamed "Hibird" due to its connection to Hibari) becomes attached to Hibari. Hibird can also sing the school's anthem as Hibari loves it. Reborn piqued Hibari's curiosity early on in the series, and Hibari considers him a worthy opponent, having a strong urge to fight him. However, he has a soft spot for small animals and later to I-Pin (in the anime) after she gave him a Valentine's Day chocolate. He hates to be indebted to anyone and strives to pay them back as soon as possible.

After being sent back to the past, Hibari soon started arguing with a transfer from Shimon Middle High School, Adelheid Suzuki, about the control of Namimori Middle School. The next day, they started fighting in the rooftop but were stopped by Tsuna. At the Ceremony, he surprised the entire Family with his murderous intent and the fact that he had decided to show up at all. He states that the people who have disturbed the peace of Namimori Middle will be bitten to death. Later, he along with the other guardians, was defeated by Enma, and their Vongola Rings were broken by him.
After the Shimon had left, Dino asked him if he was all right. Hibari replied that he was, with the exception of his pride. Later, while Talbot was upgrading the Vongola Rings, Hibari waited in a different room from Tsuna and the others. Like the others, he was able to show his resolve and upgraded his Vongola Ring. His ring turned into the Bracelet of the Clouds Version X.
Relationships
Mukuro Rokudo
Hibari displays bitter resentment and rivalry towards Mukuro Rokudo due to humiliation over his defeat. As such Hibari appears to have developed an obsession to defeat Mukuro and from this, a hate for all illusionists. Reborn is even able to quell Hibari's rage by using the posibility of him fighting Mukuro again. Mukuro seems to have some interest in Hibari, after he was able to move with so many injuries. He even have his subordinates Ken, Chikusa, and Chrome to watch his match against Gola Mosca. In the future, they still continue with this rivalry and have yet to finish (since Mukuro is still imprison). However, they seem at least, to have a respect towards each other, Mukuro even sent a map of Melone Base to Hibari when he disguised himself as Byakuran's subordinate.
Tsunayoshi Sawada
In the Databook, he commented that he can't understand Tsuna since he's weak sometimes and strong sometimes (Dying Will Mode). At first, Tsuna didn't interest him, but in the Future, Tsuna already gained his respect. Hibari states the only two people that make him joyed to fight is Reborn and Future Tsuna. Together with Irie and Vongola Decimo (Future Tsuna), they planned to send Tsuna and the other Guardians from the Past to the Future. Tsuna also sees him as valuable comrade at fighting and thinks very highly of him. More often, though, Tsuna sees him as a scary person and doesn't want to incur his wrath.
Ryohei Sasagawa
Both of them are the two oldest Guardians. Ryohei acknowledges Hibari's power and had already visited his house several times to challenge him but was always beaten by him (according to the artbook). On the other hand, Hibari only sees him as a "noisy animal" and treats him like the others. However, in the Future, they seem to already have a respect toward each other. Ryohei even invited him to drink together at some event which Hibari refused, and sometimes their thoughts clash with each other and create an argument, which ends up with Ryohei challenging him to fight. In the Inheritance Succession Arc (anime only), Ryohei is the only one who managed to convince Hibari to take the trial. This makes Ryohei the second person to be able to convice Hibari on something, after Dino.
Dino
He is Hibari's home-tutor during the Ring Conflict. But Hibari doesn't see him as his teacher and doesn't care about it, only wanting to bite him to death. Dino sees him as his student and acknowledges his skills when he trains him, but also finds it hard to train him since Hibari has no interest in listening to him. Moreover, Dino seems to be the only one who can convince Hibari to stop fighting, though at first, it was very hard to do so. However in the Future, he is able to convince him more easily and always accompanies him if he "runs off" because of his dislike of crowds. They are not on good terms or close to each other, but Dino thinks of him as a reliable Guardian for Tsuna. Hibari doesn't seem to hate him, although he is sometimes irritated by him.
Abilities and Weapons
Vongola Cloud Hedgehog
In the Future, Hibari has become adept at using Rings. His Flame has become so intense that, he shatters normal Rings when he uses them. The younger Hibari is also capable of emitting a massive Dying Will Flame with the Vongola Ring. His capacity to create a powerful Dying Will Flame is due to his resolve; his "irritation" for others.
- Bracelet of the Clouds Version X: The upgrade to the Vongola Cloud Ring combined with Roll.
- Tonfas - Hibari's Tonfas have also been shown to have hidden compartments containing other weapons like chains or needles.
Hibari's Cambio Forma
- Cloud Hedgehog - When used, a hedgehog is shot towards the target. Due to the Cloud's Ability, Propagation, the hedgehog can become bigger when it takes in Dying Will Flames.
- Vongola Cloud Hedgehog - It appears as a Hedgehog with larger, but fewer, spikes than the Cloud Hedgehog. Hibari named it "Roll."
- Cambio Forma: Alaude's Handcuffs - Hibari's Cambio Forma takes the form of a pair of Handcuffs with spikes on one end. Hibari can multiply it using the Cloud Attribute's Ability propagation by absorbing his enemy's Flames or using his own. These Handcuffs can also increase in size and envelope the enemy in a cocoon of Cuffs. Hibari can then shrink the Handcuffs, crushing his opponent.
Character Reception
On November 7, 2007, a character CD entitled "Sakura Addiction," featuring Mukuro and Hibari, was released, and became the most successful Reborn! character CD, debuting in ninth place in the Oricon charts. The single reached its peak at seventh place, but remained in the chart's Top 40 until mid-January of 2008. It contains duets and individual songs sung by both voice actors: Toshinobu Iida and Takashi Kondō. There are two available covers; both show one character as the main feature, with the other shown in the background with his back turned. The song "Sakura Addiction," which was a duet sung by both voice actors, was used as the fifth ending theme for the series.
