Details are described in corresponding sections.
The mission starts near a shrine. The door nearby are currently locked. Turn left and keep going forward. Don't enter the place with burned houses but keep going. Behind one of the rocks you will find Kodama.
Go back to the burned village. While passing through it you can defeat a few weaker enemies. Once you reach the well, you will see fire on the right. Destroy the barrels and water will pour out on you. Walk through the flames and send away Kodama. Climb the stairs to the next part of the location. Watch out for the enemy with rifle. You can climb on the roof of one of the buildings and drop down the barrel. This will eliminate the fire that blocks passage.
Keep going forward. At some point you will see a Nurikabe on the wall on the right. After defeating him you can send away Kodama and unlock a shortcut next to the shrine. Thanks to it you will be able to skip the whole burned village and safely reach this point whenever you die. Walk through the location while defeating the enemies on your way. The best solution is to reach one of the roofs through the ladder and to eliminate the enemies with a ranged weapon. Pass through the bridge on which you must defeat Wheelmonk. Activate the shrine on the left.
Another place you must reach can be seen on the above picture. In order to avoid walking through the fire (even with the water status active), you can get to the other side through the building on the left. Inside it you will have to face a few dwellers and a soldier. Once you're on the other side, don't jump down yet. Walk to the back of the building and you will find a Kodama.
Kill the yoki and go to the lower floor. Pour yourself with water and enter the fire. Defeat the Oni-bi and collect the key to warehouse from the corpse. In the warehouse you will find some interesting items. Go back up and go forward through the path. Watch out for the wheelmonk that will appear from the fog. Climb the ladder and jump down on the wall where you can send away Kodama. Then go back to the same place. Keep going forward until you reach a shrine.
Inside the building
In front of the shrine you will see a locked door. You can open it from the other side. In order to do it, go behind the building, jump down and defeat the Wheelmonk. Then go across the walls to the other side of the building. There you can unlock a shortcut to the shrine. After walking inside you must defeat a few enemies while avoiding the fire. Go to the lower floor and in one of the rooms you will find a Kodama.
Go back up and defeat all enemies that can be found there. Then go down the ladder behind the demon. You will open another shortcut to the shrine. Use the ladder next to the stairs up to find a hot spring. Then climb on the higher floor.
Follow the marker and open the door to the large room. Watch out for the shooters located at both sides, between the flames. Kill them with a ranged weapon. Then defeat the yoki that will come from the fog. Open the door on the other side and use the stairs to get up. Open the door and face the boss, Saika Magoichi.
