After the Mirror of Inverse Life, Tomoe and Elena did not experience any other danger for quite some time. During this time, they also came across another special tornado with a higher level of power. Tomoe again used this tornado to practice her mental powers again. This expedition through the Yin-yang Inverse Mountain was turning out very beneficial for her.
After walking for 1 whole day, both of them were about to reach the top of the mountain. But just before they were able to reach it, the final obstacle on their way appeared before them. It was actually a pair of black and white rocks rotating around one another. These rocks were small, just the size of a regular egg. But the amount of danger that Tomoe felt from it was insane.
