In this chapter, we learn that the interstellar army has sent a detachment of soldiers to the temple, and that it is time to take back the sea from the "evil scum" who polluted it. The two girls are waiting for the parts to be repaired, but they are interrupted by the sound of a strange string of ether, which they believe to be the life signature of witch. They have to be careful because the string is made of ether and can easily be broken with a physical force. The girls are too close to each other, and they are afraid that the enemy is using the string to attack them. They decide to cut the string, but it is still there, and the two girls hate each other.
