Kyoya Hibari, commonly referred to as Hibari, is one of the major characters in the Katekyo Hitman Reborn! series. He is the leader of the Namimori Middle Disciplinary Committee, a group of delinquents who are all loyal to him. He was nominated and accepted as the tenth generation Cloud Guardian of the Vongola Famiglia. He is often seen napping on the rooftop of Namimori Middle School, alongside Hibird.
Hibari is a young man with an average height and short black hair with a fringe that joins at the center of his face. He has narrow gray eyes, often intimidating those who see them. He bears a striking resemblance to the first generation Cloud Guardian, Alaudi, as well as the Arcobaleno, Fon.
Hibari's most common outfit is his Disciplinary Committee uniform. He wears a white long-sleeved shirt, black pants, black shoes, and a black gakuran top worn on his shoulders, with the committee's armband pinned on the top's left sleeve. He also wears the standard Namimori Middle School summer uniform, along with the armband. During the Varia Arc, Hibari wears the winter uniform, also with the armband.
Ten-years-later Hibari has changed to wearing a simple black suit, with a purple shirt and black necktie. His hair is also shorter, having been cut to appear messier, and with hardly any fringe. When not training or fighting, he would wear a black kinagashi.
As stated by others, Hibari is a scary character with little to no care for the well-being of others, preferring to do whatever it takes to get what he wants. He has full confidence in his own strength and power. This often leads to his opponents surprising him, as he doesn't think before attacking. As the head of Namimori Middle's Disciplinary Committee, Hibari uses authority to assault those that get on his nerves, including his own subordinates. Hibari is fiercely loyal to his school and its rules, going so far as to punish others for breaking them even if they aren't students or at the school, such as Genkishi.
A lone wolf by nature, Hibari prefers to be alone and hates crowding. This leads him to beat anyone who he thinks is crowding around him too much.
Hibari dislikes working together with anybody due to feeling indebted and restrained. He strives to pay them back as soon as possible. He cannot stand being restrained and absolutely refuses to allow himself to be controlled. For this same reason, he also refuses to follow order or direction from someone else unless there's absolutely no choice.
A rare trait about him is his love for small animals, ranging from birds to hedgehogs. He is also shown to have a soft spot for I-Pin, having accepted her Valentine's Day chocolates with a smile and not taking money from Tsuna at a festival upon seeing I-Pin worried. And despite his refusal to consider Tsuna and his friends as his comrades, he had saved them on several occasions when they are in mortal danger, albeit distantly. Also, during the arc of the rainbow curse, Hibari stated that Reborn's team was full of people he wanted to fight, which can demonstrate that he is starting to develop a certain level of respect for them. Although Hibari appears to take little or no care for the well-being of others, Hibari is not heartless enough to sacrifice someone's life to fulfil his own ego, as shown when he didn't try to destroy Chrome's Cortina Nebbia after Demon Spade revealed that she'll die if the barrier is broken. Hibari's hatred of being controlled is so great that this alone made him overcome the effects of a poison that would kill even a wild elephant during the Battle of Sky. Reborn has already stated that it is this indomitable and solitary nature of Hibari that makes him perfect for the rank of Guardian of the Cloud,as this is the Guardian who protects and serves the family distantly and independently while going his own way unhindered.
Future Hibari is shown to be more calm and observant about his opponents, and outwardly admits to hating illusionists because of his grudge towards Mukuro Rokudo, the first person to have defeated him. His desire to be alone and attack people that annoy him still remains, though his actions are shown with more thought. Future Hibari is also seen being more respectful to Future Tsuna, showing that he has accepted him as his boss, seen in one of the flashbacks of Shoichi Irie.
Hibari's reputation as a frightening individual definitely precedes him, earning the respect and fear of many people, both present and future. He is the strongest of the tenth generation Vongola Guardians and has hardly ever lost a fight in the series. In the times he faced against Gokudera and Yamamoto, he easily defeated them in their first initial encounters. Afterward, they grew strong enough to give him a challenge, but still not enough to excite him, as the only ones that could do that were Reborn and Future Tsuna.
One of the most terrifying traits of Hibari is his immense resilience and endurance. He is still able to fight despite having several broken bones and even capable of resisting Death Heather poison that was capable of stopping elephants from moving. Later on, Hibari has become very adept at using Rings, although he usually shatters them after one use, due to the intensity of his flames. Hibari is capable of emitting massive Dying Will Flames with the Cloud Vongola Ring. The massive flame overloaded his Box Weapon to the point it made the Porcospino Nuvola drunk from the flames, causing it to go out of control.
Learning from his defeat against Mukuro along with his hatred against all illusionist from it, Hibari has learned various ways to fight against enemies who uses illusions. He is also became perceptive enough not to be easily deceived by illusions of Mukuro's and Mammon's level.
- Cloud Flame Radar: Hibari uses his Ring's Flames as a radar by thinly spreading the Flame over a wide area and using the vibrations to detect anything that enters the area. This allows him to counter illusions by using it to sense where the actual object is, as seen in his battle against Genkishi's Spettro Nudibranchi.
- Tonfas: Hibari's main weapon for combat is a pair of tonfas. It is revealed that they hold hidden compartments. The ends of the tonfas can release flails and the sides contain spikes and hooks.
- Porcospino Nuvola: Hibari's Box Weapon, nicknamed as Roll. It is a small purple hedgehog with silver spikes. Hibari uses his hedgehogs when he fights opponents he deems as weak. With Cloud Flame's Propagation characteristic, Roll is able to multiply in number and grow to large proportions.
- Porcospino Nuvola ver. Vongola: Hibari's original Cloud Hedgehog Roll is later integrated into his Vongola Box. It now appears as a Hedgehog with larger, but fewer, spikes than the other Cloud Hedgehogs.
- Cloud Vongola Ring: Won after the Vongola Ring Conflict against the Varia. Hibari wears the Ring on his right hand. He is able to open Cloud-attribute Box Weapons.
- Bracelet of the Cloud Version X: The upgraded Vongola Cloud Ring, combined with Hibari's Vongola Box animal Roll. In battle, Roll now has jewels on both his forehead and chest. He is now capable of merging directly with Hibari for his Cambio Forma.
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 2008.
