He especially looks up to Gouenji, and eventually Tobitaka as role models. His hissatsu techniques: [Season three] Tiger Drive, Tiger Storm (with Gouenji), Gladius Arch, RC Shoot, Grand Fire (with Gouenji and Hiroto)

Kazuma is a rich, well known computer games programmer. He often helps to find information on his laptop computer, which he carries around with him all the time. At first after learning that he was a member of Class Q (which at the time was believed to be the lowest) he tried to get transferred in Class A. However, when his classmates came to his aid when he was in trouble he changed his mind, preferring to stay with his friends. Kazuma has a friendly rivalry with Kinta due to their different approaches to detective work. Kazuma and Kinta are often the butt of each others jokes. He is a very smart prodigy, but he can't get right answers without his "lucky" hat as implied in episode 2; he seems to get over this flaw by the end of the TV series. (Source: Wikipedia)
Amelie's husband. While he doesn't seem to mind traveling alongside his wife, he's seemingly more interested in reading about the various sights and happenings around Neo-Venezia. He has a slight temper, and at first heavily underestimated the work it took to become a Prima. This, coupled with his vocal displeasure about spending the full day on a gondola is what earned them the opportunity to witness the girls' training later on.
Tsuna is set to become the tenth generation boss of the Vongola family. In school, Tsuna has been given the harsh nickname of "No Good Tsuna", as he is very clumsy, gets low marks in school and is somewhat of a pushover. Although he is the tenth generation Vongola boss, Tsuna is unwilling to take part in anything that has to do with the Mafia. He always denies the fact that he is a future Mafia boss and tries to avoid anyone involved with the Mafia. In the Future arc he states that he would rather destroy the Vongola family than accept its bloody history. Tsuna is often surprised and horrified (for a comedic effect) at Reborn's and other mafiosos' actions. Later, even though he still wants nothing to do with the Mafia, he is grateful for the friends he has made since meeting Reborn. He cares a lot for his new 'family' and would put himself in the way of danger in order to protect them. There have been many parallels that link Tsuna with the first boss and founder of the Vongola family, Giotto. Both of their personalities are likely to be very similar as it has been shown that they have similar goals and ways of standards.
