The Beast of Reincarnation Blue Key is on the mountain trail above the Abandoned Village, beside a small campsite and marked by a purple-glowing pickup. Follow the quest marker, use Emma's vine-like hair to climb the mountain route, and collect the item at the camp. Reliable walkthroughs report no required major enemy fight on the direct path.
Start at the three-key gate
The Blue Key belongs to the early Chapter 1 objective that blocks progress through a sealed gate in the Abandoned Village, also called Subcity 03 in walkthroughs. Begin by inspecting the gate and speaking to the nearby NPC. That conversation gives the Red Key and establishes the remaining search.
Starting here matters because wandering the mountain before the objective is active can hide the context for the marker. Make sure the quest is tracking the colored keys. The exact localized objective name is To be confirmed because menu text differs by language.
Follow the mountain marker
From the village, track the Blue Key objective and move toward the mountain route. Look for a traversal point that uses Emma's vine-like hair rather than an ordinary staircase or doorway. The climb leads onto a trail above the lower settlement.
Continue along the path toward a small campsite. Both checked launch guides describe the destination as a camp or campsite on the mountain trail. If the marker seems vertically close but unreachable, scan above for the hair-climb point instead of circling the lower buildings.
Pick up the Blue Key
At the campsite, look for a purple glow on or near the ground. Interact with that pickup to obtain the Blue Key. It is not awarded by the Red Key NPC and is not the reward for the Yellow Key cave enemy.
The direct route is reported not to contain a formidable required enemy. Ordinary threats or conditions can still vary with your approach and game state, so stay prepared. No special code, color puzzle, or invented numerical sequence is needed.
If you cannot find the climb
Use the objective marker as a height cue rather than only a horizontal compass direction. Emma's hair traversal can be easy to overlook when the environment appears to end at a wall or ledge. Sweep the camera upward and along the rock face for an interaction point.
Return to the gate if no Blue Key objective is visible. Speak to the NPC, complete the dialogue, and verify that the Red Key has been received. A route video recorded in a different language may use another place name, but the mountain, campsite, and purple pickup remain the reliable landmarks.
Returning to the gate
The Blue Key is only one of the three items needed for the main gate. After collecting it, obtain the Yellow Key through the separate cave and rice-field route if you have not already done so. Then return to the sealed gate and interact with it.
There is no verified requirement to use the keys in a particular color order. The quest tracks possession of all three. Claims about alternate sequences or secret rewards are To be confirmed unless a current in-game record demonstrates them.
How it differs from the Red and Yellow Keys
The Red Key comes directly from the NPC beside the gate, so it is a dialogue reward. The Blue Key is a traversal and pickup objective on the mountain. The Yellow Key route is longer and involves the cave path described by launch walkthroughs.
Keeping those methods separate prevents wasted searching. NPC for red, mountain campsite for blue, and cave route for yellow is the practical memory aid. This guide does not invent exact meters or compass bearings because the game's marker already supplies the changing direction.
Optional uses remain unconfirmed
Players have discussed colored keys in relation to optional locked areas, but precise Blue Key door locations and rewards are not consistently verified by the sources reviewed. Those uses are To be confirmed and are not required for this early progression gate. Do not follow a claim that promises a specific reward without showing the current version and map context.
Quick route recap
Activate the three-key objective at the Abandoned Village gate, follow the Blue Key marker toward the mountain, and use Emma's hair to climb. Continue to the small campsite and collect the purple-glowing item. Once the Blue Key is registered, finish the Yellow Key route and return to the gate.
