Using the power of Cosmic Energy, aka friendship, we were able to defeat the Zodiarts and stop them from opening a black hole that would turn into a warp gate. That resulting explosion would have destroyed Japan completely in the process of warping to the center of the universe.

For the record? The teacher in the replies above you, Gentarou? He's the one who stopped it with our friendship and acceptance of the Zodiart leader, our Principal. Talk to him about it.
