Guin Saga is a fantasy series centered on the man with the leopard head, Guin. He has no memory except for his name and the word "Aurra". The kingdom Parros is attacked, and the twins (prince and princess of the crown) have to escape. Those two, Rinda and Remus (guess which one is the male and which one is the female), begin off as the most annoying characters. They whine endlessly about their misfortune. Guin receives little character development actually. He is a strong character both in brains and brawns. No one can stop him. He is the perfect person, I guess. There is another character introduced, Ishtovan. He is a rouge-type character, mischievous and full of tricks.
The music is simply awesome. Composed by Nobuo Uematsu, the guy who did much of Final Fantasy's music, the battles are intense, the quiet scenes are quiet, and everything seems to fit.
If you watch Guin Saga, do not look for action. The series focuses on the politics of war, the diplomacy that brings everyone into conflict, and the characters' feelings for each other. Fights are short but beautiful. The big wars are poorly shown, though. Overall, Guin Saga is a very solid series.
