Western Science Fictions and Fantagies

I'd like to find Harry in Vol.6 to be more grown-up. In Vol.5, he lost his temper so easily that he should have been swallowed by the dark side if he were in Star Wars, like Anakin. In "Wizard of Earthsea" the hero boy wizard, Ged, is so passionate and proud that he releases s shadow from the dark side of the world. A boy with a quick temper might be one of popular figures in Western fantagies, while, in Japan, Pikachu's master is a childish carefree boy who is almost always being taken care of by his friendly fellows. One of the most popular figures in Japanese history is Yoshitsune of the Genji clan. He is said to have been a genius in battle fields but a poor or childlike (childish?) politician at court. He is often taken care of by supporting players such as Benkei. Do you know the Japanese phrase "Hogan Biki", the sympathy for the weak or a tragic hero? Hogan is Yoshitsune's position in the Imperial Court. A matured statesman could hardly make a tragic hero. Laws to privatize Japanese post offices are on the House of Councillors now. I wonder if Prime Minister Koizumi is trying to be a winner or a tragic hero.
