You get the Cirrus Sword in Chapter 1 after reaching the Towards the Nushi’s Lair main objective, opening the Subcity 03 hatch, speaking to the Retired Gatekeeper at Nushi’s Lair: Gate Approach, and picking up the sword beside him.
Get the Cirrus Sword as soon as the Towards the Nushi’s Lair objective sends you toward Subcity 03. It is one of the best early detours in Beast of Reincarnation, giving Emma a stronger katana before the weapon pool opens up.

KEY!
The Cirrus Sword is worth grabbing early because it is a reliable general-purpose katana, not a narrow counterpick. It gives you a clean damage option while Chapter 1 is still teaching its route, camps, and key-door structure.
The Attack, Impact damage, and shared damage buff make it better than a simple early pickup. Enhance it once at camp and it comfortably carries routine fights plus the tougher late Chapter 1 stretch.
Earliest point for the Cirrus Sword
The Cirrus Sword becomes available during the Chapter 1 main objective Towards the Nushi’s Lair, which appears in the objective tracker before you head for the underground route.
Before that objective, push the main story instead of hunting the lake entrance early. Once the objective is active, the hatch into Subcity 03 is the route to the weapon.
How to get the Cirrus Sword in Beast of Reincarnation
Follow the Chapter 1 story route into Subcity 03, then claim the sword in the Gate Approach chamber.
STEP 1/6
Reach the Nushi objective
Progress Chapter 1 until Towards the Nushi’s Lair appears in the objective tracker.
STEP 2/6
Open the Subcity 03 hatch
Go to the northern lake entrance and use the large winch to open the underground hatch into Subcity 03.
STEP 3/6
Use the Gate Approach camp
Follow the underground route until you reach the camp at Nushi’s Lair: Gate Approach.
STEP 4/6
Check the sealed door
Interact with the large locked door or control panel ahead to start the key-door sequence.
STEP 5/6
Speak to the Retired Gatekeeper
Talk to the damaged Retired Gatekeeper beside the sealed door and receive the Red Key.
STEP 6/6
Pick up the Cirrus Sword
After the conversation, collect the Cirrus Sword standing in the ground beside the camp area.

Missability of the Cirrus Sword
In normal Chapter 1 progression, the Cirrus Sword is part of the route rather than a true missable. The key-door sequence brings you to the same underground character and the same room, so you pass close to the pickup while handling the Red Key.
If you see the character described as a weakened Golem instead of the Retired Gatekeeper, that is the same seated NPC beside the sealed door. Grab the sword when it appears so you do not have to return to Nushi’s Lair: Gate Approach just for the pickup.
Upgrade path after collecting the Cirrus Sword
Once you have the Cirrus Sword, equip it and check Enhance Equipment at the nearby camp. Spend Amber on the early upgrade because the weapon stays useful beyond the room where you find it.
Upgrade the Cirrus Sword to +1 before the Chapter 1 finale if you want a stronger damage buff for Emma and Koo.
Keep it as your default blade into Chapter 2 while it is outperforming your other general options. Start swapping more often once elemental katanas give you better answers to specific enemy weaknesses; at that point, the right element can matter more than comfort with one favorite sword.

Frequently Asked Questions
Can you get the Cirrus Sword before Towards the Nushi’s Lair?
No. Get it after Towards the Nushi’s Lair is active in Chapter 1, because the Subcity 03 hatch route is tied to that point in the story.
Should you keep using the Cirrus Sword after Chapter 1?
Yes, unless you pick up an elemental katana that directly suits the enemy you are fighting. The Cirrus Sword remains a strong general blade into Chapter 2, then becomes more situational as weakness matching gets more valuable.
