In this chapter, we learn that the shadow sword is being used to create a barrier between the two swords, and that the barrier is being created by the combination of both the tenchu and the shadow swords. In other words, the sword that is supposed to protect you from the evil spell is actually the one that will protect you against the good spell. The only problem with this is that the sword is a combination of two swords that are perfectly in harmony with each other. The problem is that all of the swords are in perfect harmony with one another, and the only thing that separates them is the fact that they are both wearing the same bracelet.
