Kyoya Hibari

Kyoya Hibari is a fictional character in the anime and manga series Reborn! created by Akira Amano. For the most part of the series, Hibari is portrayed as an anti-hero, taking little to no interest in the events that surround the main protagonist, Tsuna Sawada. He is introduced as the leader of the Disciplinary Committee at Tsuna's school, Namimori Middle. Despite his status, he is a delinquent who uses violence to create his own form of order in school, as well as enforcing it throughout certain parts of the town of Namimori.

Hibari is the leader of the Discipline Committee of Prefects, who all are delinquents loyal to Hibari. Like his subordinates, he too is a violent delinquent who uses his status to keep his own version of 'order' among the other students. However, he prefers to be alone and cares little for his subordinates. He hates people clustering. His catchphrase is "I'll bite you to death" (kamikorosu), which he says to everyone whom he is ready to fight. This isn't limited to actual combat instances. He has a tendency to say this to pretty much anyone who is standing too close to him, making too much noise, or creating a rucus of any kind.

Hibari is very proud of his school, and is apparently the only person who likes their school's anthem, even using it as his ring tone. In the Kokuyo Arc, he adopted the Kokuyo assassin Birds' bird. The bird (subsequently nicknamed "Hibird" due to its connection to Hibari) becomes attached to Hibari. Hibari has a soft spot for animals such as Hibird, and also seems to feel at least a modicum of compassion for small children, as he has at least on one occasion refrained from beating people to death, simply due to the presence of Lambo and I-pin. Subsequently, due to Hibari's resemblance to the Arcobaleno Fong, I-pin has a bit of a crush on him, and even gave him chocolates on the Valentine's Day episode.

Reborn piqued Hibari's curiosity early on in the series and Hibari considers him a worthy opponent, having a strong urge to fight him. After Tsuna passes the test for the inheritance of the Vongola, the Hibari of the future comments that Tsuna starts to resemble the one he knows, who excites him as much as Reborn does. In the anime version, he has the tendency to say "Wao," (like "wow" in English) whenever he's impressed or being sarcastic.

It has been noted that Hibari is exactly like the first Vongola Cloud Guardian. The first Cloud Guardian had been the head of a country's secret intelligence division, never stood alongside the Family, hardly got along with anyone, and preferred being alone. However, he and Vongola Primo had one thing in common that allowed them to work together, in that they defeated the most enemies and were benevolent to comrades.
