The one named "Lucciola" here is not a girl. Also, these are two boys.
If you’re a great writer, and I know you are, then you should be able to take a personality type that has been known to really boil my goat in the past, and eventually turn me sympathetic toward the character holding that personality. One recent example for me was Dio from Last Exile, which is a highly recommended 26-episode series, if you like any kind of sci-fi. You can watch the dubbed episodes on Netflix or all the subbed episodes on Youtube.
Dio comes from a high-technology society, the Guild, that antagonizes the rest of the nations in Last Exile. At the outset you take him as villainous because of his background but he ends up unofficially expatriating to do some weird, partially homoerotic/piloting fetish flirtation with the series protagonist, Klaus.
Basically, Dio acts like a toddler, though he is a skilled pilot and is constantly in the face of danger. He has an annoying whimsy about him that excessively-talented people tend to have in movies, where they consider life-threatening situations as gameplay and other people as playthings. Prodigies are supposed to get bored with their expertise easily in Hollywoodland, it seems. It doesn’t help that his English-cast voice hints at arrested development, which would fits nicely in with his history.
It all turned around for me one episode, where his oblivious demeanor is cracked and he executes a super-freakout during non-combat flying. It literally comes out of nowhere in a scene where lots of things come out of nowhere.
Dio’s story is pretty tragic because we learn the Guild’s method of selecting its ruling elite, the place in which his intended fate sits. It takes until the end of the series for his psychological history to sink in, but losing all control of your ship from a complete breakdown seemed to be an appropriate response when threatened with a destiny like that.
