I just finished reading the first volume of Nausicaa of the Valley of the Wind. There was a scene that confused me in an earlier part of the book. I don't remember the page numbers.
When Princess Kushana lands her gunship in the Valley of the Wind, Nausicaa rushes in and challenges one of the soldiers to a duel (essentially). After the situation is defused by Master Yupa, Kushana asks if she can see Nausicaa's sword. Nausicaa hands over her sword, Kushana admires it for a moment and then cuts it to pieces with her own sword. There doesn't seem to be much of a reaction from Nausicaa or her people when this happens and the fact that Kushana destroyed the sword is never mentioned again.
What I don't understand is, why is the act of Kushana breaking the sword not more significant? Apparently the sword was made of ohmu shell, which is supposed to be tougher than the ceramic blades used by most soldiers (evidenced when Nausicaa chips her ceramic blade on an ohmu shell in one of the first scenes of the book). Furthermore, ohmu shell swords must be incredibly rare, considering that Kushana (who is the princess of a large empire) would be carrying an "inferior" ceramic blade. Wouldn't that sword be like a family heirloom or something?
The only explanation that I can think of is that the scene is purely intended to set up what a badass Kushana is and that Nausicaa is not upset because it is a small price to pay to get the Torumekian forces to leave peacefully.
Note: I have only read the first volume, which ends shortly after Asbel gets shot down by Kushana's gunship. I don't care about spoilers if you need them in your answers, so fire away. I have not watched the anime either.
