Available: Subaki marries another female character
Recruitable Character: Caeldori
In this map, your main character and Subaki will be fixed members. This is a large map with a lot of enemies. Furthermore, your army will be surrounded. You don't need to go out and engage the enemies. You can fight them on the forts to gain terrain advantage, to whittle their numbers and allow you to maintain your formation.
Shortly after starting the battle, Caeldori will arrive and join your army. Once ready, the Hero in the middle of the southern island should be your priority target. Once done, let the enemies come to you and use the intervals to heal your characters as necessary. Once all attackers have been dealt with, make your way to the NE to engage the enemy leader's group. You have to fight defensively in this battle and use the forts to gain terrain advantage and constant HP recovery. The enemies will continuously and aggressively attack you so thin out their numbers first before moving out.
