Red, Blue & Yellow Keys in Beast of Reincarnation — Locations Guide
Where to find every key in Beast of Reincarnation: the Red Key, Blue Key, Yellow Key and Tailwater Key, how they open the Nushi's Lair and strongboxes, and what to do once you have all three.
Red, Blue & Yellow Keys in Beast of Reincarnation — Locations Guide
Beast of Reincarnation has a three-key questline running through Chapter 1: the Red Key, Blue Key and Yellow Key, which together open the Nushi's Lair. A fourth key, the Tailwater Key, appears in the same early region family. If you've searched for any single key and landed here, this is the full picture — including what each key actually unlocks.
The Three Keys: What They're For
The Red, Blue and Yellow keys are the Chapter 1 objective thread. Collecting all three opens the Nushi's Lair — the lair of the region's Nushi, where the chapter's boss fight happens. The key locations are documented consistently across IGN's key wiki, Sportskeeda, VGC and the community key videos:
- Red Key — the Abandoned Village region; the path is flagged "Path to the Sealed Lair". Eurogamer confirms the Red Key is the key tied to the Sealed Lair gate
- Blue Key — documented by Sportskeeda's dedicated guide; the exact landmark varies by walkthrough, but the blue key is a Chapter 1 pick-up tied to the same questline
- Yellow Key — same region family as the red and blue; collected along the same objective path
The sources agree on which region each key lives in (Abandoned Village / Cliffside Village / Disposal Site family) but give slightly different landmark descriptions. Rather than a single precise screenshot-marked spot, follow the objective marker for the "collect the keys" quest — the game leads you to all three in order, and the strongbox codes guide covers the boxes tied to the same regions.
The Tailwater Key
The Tailwater Key is a fourth key in the same early-region family, appearing in the community key videos alongside the three main keys. It opens a specific locked gate on the Tailwater route — worth picking up when you're in the region since the path it unlocks contains blades and a campsite.
Keys vs. Strongboxes: Don't Confuse Them
Keys are not the same as strongbox codes:
- Keys open gates and lairs (Red/Blue/Yellow → Nushi's Lair; Tailwater → a route gate)
- Strongboxes are locked chests opened with 4-digit codes (04180, 08110 and others) — see the strongbox codes guide for every code
What You Get from Opening the Nushi's Lair
The Nushi's Lair contains the chapter's Nushi boss fight. Defeating it triggers Boss Stealing — you capture its power as a loadout (the game's core progression loop, explained in the beginner guide). The lair's chests also hold blades and upgrade materials, so the keys pay for themselves twice over.
The Nushi's Lair fight is the Chapter 1 difficulty peak. Doing it before you move on means you enter Chapter 2 with the captured loadout plus the lair's materials — exactly what the game's difficulty curve assumes.
