Part 64 of 66 in Tales of Tsushima
It unlocks after you rescue Taka in The Broken Blacksmith. Return to Azamo Bay and talk to the villagers near the main gate.
Taka is safe, but the rest of Azamo Bay is still a prison camp. Villagers say the Mongols are starving and punishing the elders. You go back to finish the job.
Talk to the villagers near the main gate to learn about a gap in the fence, and slip in through it. Then, in any order: free villagers from 3 cages, kill 3 Mongol leaders, free 3 elders and open 3 gates. When all are done, find and defeat the warlord, then raise the village banners. Harunori only appears once the four sets of tasks are done.
The fence opening lets you start quietly. Use it to pick off leaders and free prisoners before the whole village is alerted.
