Go to Lynn in front of the Security Bureau, and talk to her to start a brief cutscene.
Lynn will assign you a list of tasks to carry out. She will also order you to talk to Clive, a high-ranking officer of the 13th Legion.

Exit the city gates and turn to your left where you can find parked trucks and stacked crates. You'll find Clive with another Legion soldier.

Snow Wolves will ambush you before you can approach Clive. Defeat 20 Snow Wolves before you can talk to Clive.
Once all of the wolves have been defeated, you can now talk to Clive, who will issue you the full list of tasks that you, Rhythm, Outsider, and Snow must complete to assist with the investigation.
Rhythm will set off for a while to complete her own tasks.
| Prompt 1 | ||

Meet back up with Rhythm. You can find her at the northern exit of Icelake, near the pond.

During a short cutscene, Rhythm will tell you that she has been gathering essential goods for residents of Mist Aken. The group will volunteer to help Rhythm catch and distribute food. Afterwards, go to the nearby pond and catch 3 fish of any kind.

If you're out of bait, you can purchase some from the Angler Shop. The shop can be found in Icelake Suburban Square.
| Prompt 1 | ||

| Wow, you sure don't know how to take it easy, do you? I know, I know, save the "It's my duty" speech this time. | ||
| Response | Impression | Points |
| Let us help you. | Morality | +3 |
| I'm running low on supplies too. Can you get me some Phoxenes? | Chaos | +3 |

Find Margie in Mist Aken to hand over the food. She can be found standing in front of the notice board near the entrance behind The Asphodel.

Your conversation with Margie will be cut short when Rhythm receives information that the 13th Legion will soon enter the sewers.
Follow the quest marker near the site of the incident where the Perpetrator first attacked the Phoxhunter. Clive can be seen talking to a group of soldiers.
Speak with Clive again to report for duty. He will order Rhythm and your group to head to the sewers.

Go to the sewers. You can use the manhole entrance in the area to as the best entry point.

Follow the quest marker through a short tunnel to meet up with the other soldiers from Lynn's unit. Talk to them to receive your orders.
Follow the quest marker again to a flooded area.

As with the previous subquests, you will have to drain the wastewater from the chamber.
If you ever find yourself lost during the rest of this quest, the giant blue clawmarks that can be found in your surroundings can serve as helpful markers.

Go up the stairs toward the first valve. Interact with the device and solve a drag puzzle to turn on the valve.

Opening the first valve will attract a large wave of Filthoids. You must clear the area of enemies before moving on to the second valve.

Go to the other end of the chamber to the locked gate.
Approach the large mechanism with the electrical cords attached to it. Simply interact with the mechanism to unlock the gate.

The gate next to the valve will open, leading to a large open chamber designed like a stage. Follow the quest marker and jump up some of the boxes to reach a floating platform. Begin investigating the area from there.
Observe the mannequin to move on. 
Then, follow the quest marker again to another area to investigate multiple blue claw marks left behind by the monster.

The marker will lead you to the wheel attached to the pipe. Simply hold to turn it and bring down another floating platform.

Jump onto the platform until you reach the quest marker. Investigate the curtain. The Phoxhunter will notice that the fabric matches the fabric of the stage curtain found at the crime scene.
Head further up the platforms to another wheel. Turn it to create a path forward and move higher up the chamber.

The path will bring you to another wheel. Doing this will clear the entire area of floating platforms and curtains.

During the cutscene, Rhythm's communication device will malfunction.
Interact with the terminal to start fixing it. This will bring you to a new type of puzzle. To solve it, move each white bar to the orange outline.
Successfully repairing the terminal will reveal that the rest of the squad has been warning Rhythm that the monster is nearby. However, it will be too late by then.

What follows is a difficult fight against the Perpetrator, which will later be revealed as Subject 47. The first phase of the battle will be familiar: the Perpetrator will attack you at close range and dash away frequently.
As you move on to the next phase, however, the Perpetrator will begin to use powerful attacks that can cover the entire arena.
Energy orbs will also begin to fall from above. You will have to dodge them while continuously breaking down its Stance bar.

Successfully defeating the Perpetrator will take you to a long cutscene and back to Icelake. When you're free to move, the Phoxhunter will declare that they need to figure out the identity of the Perpetrator and their whereabouts.
Start deducing the identity of the Perpetrator by combining the following clues you collected previously:
Combining these two clues will result in a new one: Operatic Melody Heard during the Attack.
Submit the clue to inform your companions of your suspect: an opera enthusiast. Rhythm will invite you to the secret base so you can figure out which aria the perpetrator was singing.

| Just you and us? | Benefit | +3 |
Go back to the Fischers' Secret Base to start listening to tapes. Approach the radio and interact with it to switch tapes. Doing this will start a series of 3 puzzles that are overall easy to solve.
The first puzzle resembles the first puzzle you solved to fix the comms terminal. Move each bar to the orange outline to solve the puzzle.
The song the Phoxhunter hears will sound similar to the aria they heard, but the tone is different. Switch to the next tape to listen to another song.
Interact with the radio again to start another puzzle. The second puzzle will require you to follow a specific symmetrical pattern. It has fewer bars than the previous one, making for a quick solve.
The second tape will also turn out to be the wrong piece.
The third puzzle is tricky compared to the other two, because two bars will move simultaneously. The key here is to focus on moving the first or left bar to its designated notch (orange outline) until you reach the end.
You don't need to worry about doing anything complicated; the last two bars will require the same number of movements to reach their respective notches.
Solving this puzzle will allow you to listen to the final tune, which turns out to be a dead end.

You, Outsider and Snow head out to meet up with Rhythm. You'll find her by one of the abandoned cars in the lot. Talk to her to start a cutscene.
Rhythm will begin singing a song that sparks the Phoxhunter's memory. They identify it as the exact same song they heard on the night of the attack—Requiem for the Nameless, from the opera Children From the Snowfield.
Just as the group begins to hatch a plan to draw out the Perpetrator with the song, it will appear before them.

Confronting the Perpetrator (Subject 47) will start a very short battle that is less intense than the previous one. Keep attacking the Perpetrator until shortly after Outsider tells you to take it down.
The Perpetrator will stop attacking, immediately ending the fight and initiating a cutscene in which the Perpetrator reveals his identity as Rhythm's brother, Blues Fischer.
Looming Winter will end when Blues begins to tell the story of his life as a Laurelled Charon.

The Perpetrator, also known as Subject 47, is a difficult story boss who moves swiftly and balances close combat, leap attacks, and bullet hell-style moves.
