What Is the Whose Leak Is This? Anomaly Commission?

Whose Leak Is This? is one of the Anomaly Commissions available in Neverness to Everness. It is set in the Miguel District and follows the game’s horror-flavored supernatural formula — a residential apartment building has been taken over by a creeping black goo, and it is your job as an Anomaly Hunter to track down the source and stop it from spreading.

Unlike combat-heavy commissions, this one is almost entirely exploration and puzzle-based. It takes place inside an elevator that refuses to behave normally, moving between floors in strange ways and exposing you to increasingly unsettling encounters. No major boss fight is required, but there is one sequence inside the elevator where you need to dodge attacks. Overall it is accessible and can be finished in a few minutes once you know the steps.

If you are working through all commissions in the Miguel District or just need help getting unstuck, this guide covers every step from location to the final interaction.

Whose Leak Is This? Location In NTE

The commission is found in the Miguel District. Here are two ways to get there:

Method 1: Use the ReroRero Phone Booth

Teleport to the ReroRero Phone Booth on Ironheart 9th Avenue.
From there, head southwest.
Look for a building with double glass doors near a bus stop.
Enter through the glass doors to start the commission.

Method 2: Navigate via Saint Torres Avenue

Head to Saint Torres Avenue in the Miguel District.
Find the Phone Booth in the area and go southwest from it.
The target building is the second building next to the Puka signboard.
Enter using the double glass doors at the front.

You can also track the commission directly. Open the Anomaly Commission menu from the bottom right corner of your map, scroll to the Miguel District section, and select Whose Leak Is This? to place a quest marker on your map.

How To Complete Whose Leak Is This? — Full Walkthrough

Once you are inside the building, head to the far end of the ground floor and enter the elevator. The commission runs across several sequential floors, each with its own interaction. Follow the steps below in order.

Step 1 — Take the Elevator Up

Walk into the elevator at the far end of the ground floor. On the panel to the right, press the 7F/9F button. The floor you choose does not matter — the commission will take over and bring you to where you need to be. The elevator shifts into first-person perspective once the commission begins, so do not be alarmed by the change in view.

Step 2 — Repair the Switch

When the elevator doors open on the first anomaly floor, step out into the hallway. You will see a picture of a silhouette at the far end of the corridor. Walk all the way to the end of the hallway and look for a switchboard on the right wall. Interact with it when the Repair Switch prompt appears. This stops the lights from flickering. Once done, return to the elevator and press a button to proceed to the next floor.

Step 3 — Answer the Telephone

The elevator will move to the next floor. The doors may not fully open at first — if they do not, interact with the panel button again to force them open. Once the doors open, walk to the end of the hallway and find a ringing telephone. Interact with it to answer the call. After the call, head back to the elevator and press the button again to continue.

At this stage, the screen may turn red and an alarm may go off. This is scripted. Nothing will happen immediately. Just press the button again and keep going.

Step 4 — Collect the Three Elevator Buttons

On the next floor, you will notice that three buttons have disappeared from the elevator panel. Step out into the hallway to find them. The floor has patches of black goo on the ground — avoid walking through them to prevent taking damage. The three buttons are scattered around the hallway floor. Pick all three up, then return to the elevator.

Once back inside, press any button on the panel. Use Force Start when the door gets stuck to pry it open and move to the next floor.

Step 5 — Force Start the Elevator (Twice)

After placing the buttons, the elevator will try to descend but get stuck again. Press Force Start on the doors when prompted. The black goo will seep through the front doors into the hallway during this sequence. After a brief moment, the doors close and the elevator moves. You may need to use Force Start a second time on the next attempt as well. Keep pressing it until the elevator moves freely again.

Step 6 — Do Not Exit the Dark Hallway Floor

The elevator will open onto a dark hallway with two black spots right in front of the doors. Do not step out here. The black goo will damage you if you attempt to leave the elevator on this floor. Instead, press the elevator button again from inside to continue to the next floor without exiting.

Step 7 — Survive the Black Goo Attack

On the next floor, the black goo will launch a spike attack inside the elevator. The spikes appear from one side of the elevator and thrust outward. Watch which side the spikes are aimed at and move to the opposite side to avoid them. You have a brief window to reposition before each spike extends. The goo will attack several times in a row. After a few rounds of dodging, the black goo retreats and the elevator moves normally again.

Step 8 — Tighten the Faucet

The elevator finally arrives at a bathroom floor flooded with black goo. There is a sink with a leaking faucet at the back of the room. Walk up to it and interact with the Tighten the Faucet prompt. Once you tighten it, the black goo dissipates completely and the commission is complete.

Step 9 — Exit the Building

After the commission ends, return to the elevator and press 1F on the panel to descend back to the ground floor. From there, exit through the front glass doors to return to Hethereau City and collect your rewards.

Tips For Completing Whose Leak Is This? Smoothly

Track It On Your Map First

Before heading out, open the Anomaly Commission menu on the bottom right of your map and track Whose Leak Is This? under the Miguel District tab. This places a clear quest marker in the city so you are not wandering around looking for the right building.

Avoid the Black Goo Puddles On the Button Floor

When collecting the three dropped elevator buttons in Step 4, the hallway has patches of black goo that deal damage when you walk through them. Take your time and navigate carefully around each puddle. There is no timer, so slow and careful movement is fine.

Do Not Panic During the Spike Attack

The black goo spike attack in Step 7 looks intimidating but is very readable. Each spike telegraphs which side it will come from before it extends. Move to the opposite side of the elevator before it fires. After a few rounds the sequence ends automatically — you do not need to defeat anything, just survive the waves.

Do Not Step Out On the Dark Floor

This is the step that trips up the most players. When the elevator opens onto a dark hallway with black spots right at the door, your instinct may be to step out and explore. Do not. The goo will damage you immediately. Press the elevator button again from inside and skip that floor entirely.

Force Start Works Every Time

Whenever the elevator doors get stuck, press the Force Start prompt. This always works. If nothing seems to be happening, check that you are facing the panel and look for the Force Start interaction prompt before pressing anything else.
