In this chapter, Mina explains to Harada that the three sacred jewels are like "the holy three sacred trinity" . Mina tells Harada about the story of the jewel and the mirror, and then explains that the sword is like the mirror because it's made of the same material as the other two. Mina also explains that all three of the jewels are revered by the gods, and that the battle in October will depend on the strength of the three.
