Credens justitiam is an example of Kajiura Yuki at her finest, when she is able to reach a harmonious equlibrium between power, beauty and kinetic elegance.
The last time she composed something so heart-pounding yet so uplifting was
Sei Otome No Inori (Prayers of the Sacred Maiden) for
Mai Otome. 
Just been inspired to make a music-video compilation of the the most heartbreakingly-beautiful/elegant Jet Li and Donnie Yen fight scenes with song.
