And hey, it works pretty well as a signal to Kai that Ryoji is back. And while Levana's troops weren't expecting a sneak attack, they were also definitely not expecting a dragon, so it's really not too long before they decide to surrender, evacuating the burning part of the building.

After he accepts the surrender, Kai finds out that Levana has fled for parts unknown, but there's no guarantee she'll get a warm welcome there, and Kai is fine with it. He goes to find Ryoji.
