After receiving new power from the Rainbow Sage, you head toward the Bottomless Canyon.

Before the Battle

You won't be able to save after this battle, but you will be able to save after the next one.

Defeat the Boss

The objective is to defeat Hans, who is in the northeast of the map.

At the start of the battle, Hinoka, Setsuna, Azama, Ryoma, and Scarlet will join your army. They start in the northwest of the map, and in theory you can just send them directly east to kill Hans, since the flames will not be blocking their path to him.

The walls of flame can be switched on or off using Dragon Veins. During the battle, the flame walls will turn off and on at intervals. You will need to keep moving your units northeast so they don't get stuck behind a flame wall, forcing a royal unit to backtrack and open the path for whoever got stuck.
