In this world...
Sawada Tsunayoshi is a graduate from a technology university who recently returned back to Italy. He works as a network engineer. Tsuna is actually very intelligent, but also socially inept and clumsy dealing with girls (he always is), often described by others as a stereotypical nerd. He likes watching scientific shows, and is a huge fan of Vocaloid (Otaku!Tsuna?). He first met Kyoko on the bus trip from the airport to the apartment and later on, he had a crush on her (cliche).
Sasagawa Kyoko is actually the daughter of a billionaire banker (Shocking indeed). She ran away from home when her father forced her to marry against her will (Yes, yes), and met Tsuna on the bus. She found various works and eventually got a job as a writer for a fashion magazine. She is smart and charming, but often thinks and acts naively and unrealistically in everyday life due to being raised in a wealthy family. She then became Tsuna's best friend, without knowing that he had a crush on her.
Rokudo Mukuro is a host for the late-night radio talk show called "Vongola." He is kind (Not really), sensitive (Again, not really), but wimpy, due to his cowardice, he has often been forced into situations that are out of his control. His catch phrase (Laugh) is,"Kufufu". Despite jokingly claiming to be a famous celebrity, his talk show is very unpopular and he is often ridiculed by his boss.
Hibari Kyoko is actually (The biggest difference from canon) Tsuna's older stepsister. However, you can treat her like 'a male Hibari in disguise' since she is tough, aggressive and very competitive, with many of her friends jokingly saying she has the strength worth two men (Two men, definitely 'male Hibari in disguise'). She often bullies her friends around (Mukuro most of the time) with her forceful personality, and expresses her sarcasm at their incompetence. She is constantly annoyed by Mukuro's wimpy and bumbling personality. In various places, you can see that she has soft spots, but always denies it to the public.
Gokudera Hayato is actually very different from canon. He is a young man who moved into the apartment, living next-door to Tsuna and Co. He is a freelancer, though often thinks of smart ideas to make money (Imagine it, Gokudera is POOR) or trick his friends into doing his bidding (though also occasionally fail and lead him to trouble). He is cunning, irresponsible, but very charismatic, and likes to use his charms to flirt with various girls. He has a constant "hate" relationship with Haru.
Miura Haru is Gokudera's "friend", who moved into the apartment with him to take advantage of a discounted rent deal. She initially worked as Yamamoto's assistant, later in a pet shop. She is childish, cheerful and ditzy, and gets easily attracted to cute things. She has a "hate" relationship with Gokudera, and often gets angry at his laziness.
Yamamoto Takeshi is a Japanese teen who also moved into the same apartment as Tsuna and Co. He was a manga artist from Japan, but left for Italy to pursue his career. He is charming and very serious, but when angered, he becomes extremely stubborn and (comically) violent, often taking out a katana and scaring his friends by claiming he will commit seppuku (An act of stomach-cutting that is a form of Japanese ritual suicide). He is still learning English and Italian, and often misuses English and Italian phrases.
