Beast of Reincarnation Blue Key, Red and Yellow Key Locations

The Ogouchi Buffer Zone in Beast of Reincarnation hides three keys, the Red Key, the Blue Key and the Yellow Key, and you need all three to open the Nushi’s Lair door. Each one also opens a locked door elsewhere in the zone with a strongbox behind it. None of the three will appear before you fight the Nushi for the first time and speak to the Gatekeeper in Subcity 03, so if the Blue Key is not showing up on your map yet, that is why. Here is where to find all three and what each one unlocks.

Quick answer:
Red Key: handed to you by the Gatekeeper at the Nushi’s Lair: Gate Approach campsite in Subcity 03.
Blue Key: at the Lookout Shack in the north, marked by a red pillar you can see from a distance.
Yellow Key: from the guardian in the cave north of Tailwater Village, behind a door that needs the Tailwater Key.

Where to Find the Red Key

You receive the Red Key from the Gatekeeper near the Nushi’s Lair: Gate Approach campsite. Once Emma walks up to the gate, he hands over the key along with hints about where the other two are hiding.

Where the Red Key is Used

Besides the gate to the Nushi’s Lair, the Red Key opens a door in the Abandoned Village with a Strongbox behind it.

Where to Find the Blue Key

The Blue Key is at the Lookout Shack, northeast of the Subcity 03 entrance. You will spot a red pillar in the distance marking the spot, so head straight for that. There is a campsite of the same name right next to it, which makes the return trip quick.

Blue Key Not Showing Up

If there is nothing to collect at the Lookout Shack, you are simply too early in the story. The keys only become available after the first fight with the Nushi, once you have entered Subcity 03 and spoken to the Gatekeeper. The key is not missing and it is not a bug. Carry on with the main quest, then come back and it will be there.

Blue Key Door Location

Besides the gate to the Nushi’s Lair, the Blue Key opens a door next to the warehouse east of the River Fork campsite. Follow the story quest to receive the key, then return to open the door and loot the strongbox behind it.

Where to Find the Yellow Key

The Yellow Key is at the end of the cave north of Tailwater Village. A bear malefact guards the way in and drops the Tailwater Key when you beat it.

Use the Tailwater Key on the door inside the cave, then talk to the guardian in the room behind it to receive the Yellow Key.

Yellow Key Door Location

Besides the gate to the Nushi’s Lair, the Yellow Key opens the locked building north of the river, east of Village by the Bridge, where Strongbox 8 is waiting.

Yellow Key Backstory

If you are here for the lore, there is a document from the golem who once carried the Yellow Key. You will find it in the back room at Subcity 02, next to another strongbox.

With the Red, Blue and Yellow Keys in your inventory, return to the Nushi’s Lair: Gate Approach campsite and use all three at the door to start the fight with the Nushi. Before you do, finish anything you still want from the Ogouchi Buffer Zone, because the story moves you straight on to the next zone afterwards.
