Haru Miura most of the time is not taken seriously by the family because of her goofiness. But ten years later, she became the one of the brains of the famiglia, the strategist and the adviser alongside with Hibari in Cedef. She was hailed as the most intelligent female in the Vongola.
To help cover the gaps in his rent payment, Gokudera secretly took up a part-time job at a small, used book store that’s owned by a quiet elderly woman.
He usually just organizes the books, dusts shelves, and helps with any heavy lifting (he isn’t let anywhere near the front counter because of his nonexistent patience with strangers).
Even though he hates to admit it, he actually enjoys working there; not only is he the only employee, but the woman he works for also likes to play classical music records and brew decent coffee for the two of them.
TYL Gokudera had left his G writings with instructions to kill Shoichi in his breifcase with the desperate hope that one day, his younger self might be accidentally caught in the ten year bazooka and would read them.
He still had no idea about Tsuna’s plan and truly believed he was dead.
Gokudera has a photographic memory, which is why he was able to fully learn Japanese in such a short amount of time.
He also has an extensive knowledge of several other major world languages, including English, Spanish, French, German, and Russian. Learning new languages and other subjects through reading is a major hobby of his.
The reason why Hibari is so obsessed with keeping order and discipline is because he lost his older brother in a car accident. His brother had been ignoring the speed limit, and Hibari thought, “Brother wouldn’t be dead if he had followed the rules.”
He’s completely absorbed with enforcing rules because he doesn’t want to lose anyone again.
Before Ricardo became Vongola Secondo, he actually had a pure Sky Flame but it was weak.
Due to the hidden manipulations of Daemon Spade, Ricardo grew to hate not only for himself but those around him, especially towards his cousin, Giotto. Thus this hate morphed with the Sky Flames and the ‘Flame of Wrath’ was created.
Ricardo did feel regret in the end of his life for what he did.
Tsuna is firm in his belief that he has eight guardians, rather than seven, and as he grows into his leadership of the Vongola, he becomes visibly enraged when people think he only has one Mist Guardian.
