"You should have used your time better, like training instead of just waiting," Billy said.
"The power of the spirits doesn't grow with training. From the moment we were born, our strength was limited to our world," The time spirit said.

From the very beginning, we only oversee that world and help the people there survive their hardships. We aren't the ones who have to save it."
