From the overlook, head southwest down the hill. At the bottom, travel west to find Kazan just before the inn. Approach him to trigger a cutscene. When you’re ready, speak with Kazan to begin the decisive battle. Afterwards, head north, crossing the stone bridge, and enter Ku: Castle Town.

Proceed north through this area as your allies hold back the soldiers.

Again, your allies will hold off the enemy forces so continue north into the castle.

Here you’ll have a series of back to back boss fights. Inside the castle, head up the grand staircase. At the top, you’ll face General Ritsu, the first boss. During the second half of the fight, Ritsu will get a boost to his shield.
