Gokudera was born in Italy to a wealthy family—he's three-quarters Italian with a Japanese mother. He's got silver hair, stands at 168 cm, and has a blood type of B. Despite his privileged background, he's best known for his chain-smoking habit, though the anime ditched this detail. He's also surprisingly skilled at piano.
At school, he's got that whole rebellious bad-boy thing going that the girls are into. During Valentine's Day, he gets swarmed by female classmates trying to hand him chocolate, which he finds more irritating than anything. What catches people off-guard is that underneath the rebel persona, Gokudera's actually a top student who aces every test. His parents probably loaded him up with private tutors growing up, which explains it.
His core motivation is straightforward: he wants to become Tsuna's right-hand man. He idolizes Tsuna and is genuinely devoted to that goal. That said, he's got a serious chip on his shoulder about people older than him, particularly Bianchi and Lambo, who he actively dislikes.
There's something deeply weird going on with Bianchi, though. Due to a traumatic childhood incident, seeing her face makes him physically ill—sometimes he passes out completely. The oddball part? If she's wearing anything that covers part of her face (glasses, goggles, whatever), the effect vanishes entirely and he's fine.
