Also, some curiosities regarding the Imperial Regalia. As you know, the Divine Instruments are based on them... don't you?
Well, each regalia stands for something. Yasakani no Magatama (inspiration for the rosaries) symbolizes benevolence. Kusanagi-no-Tsurugi (inspiration of the glaives) symbolizes valor. Yata no Kagami (inspiration for the reflectors) symbolizes wisdom or honesty.
And for some personal LULZ:
In The Tale of the Heike, a collection of oral stories transcribed in 1371, [Kusanagi] is lost at sea after the defeat of the Heike clan in the Battle of Dan-no-ura, a naval battle that ended in the defeat of the Heike clan forces and the child Emperor Antoku at the hands of Minamoto no Yoshitsune.
Geez, Yoshitsune keeps popping up everywhere when I'm reading meta ô_o Well, I guess he DOES have one thing in common with his Okami namesake...
