Understanding what Nest Guard Fragment actually is
Nest Guard Fragment is a high-value development material tied directly to Esper progression. It represents a fragment dropped from the Nestbound Bird, one of the anomaly bosses in the game. The item is primarily used during character ascension, which allows your Esper to surpass level caps and unlock stronger stats or abilities.

You won’t need it early on, but once your characters reach mid-to-late progression thresholds, this material becomes mandatory for further upgrades. That’s when farming it efficiently becomes important.
Location of Nestbound Bird anomaly
The Nestbound Bird anomaly is not just a random encounter—it is a structured boss event that you can access through the anomaly system. You need to locate and enter the anomaly zone tied to the Nestbound Bird encounter, which becomes available as you progress through the game’s content.

The fight itself is designed to be more challenging than standard encounters. Preparation matters here, especially if you’re aiming to farm fragments consistently. Bringing a balanced team with sustain and burst damage will make the process smoother.
How to get Nest Guard Fragment in NTE
Step 1
Locate the Nestbound Bird anomaly from the anomaly menu or map. Make sure the activity is available and you meet any level or progression requirements.

Step 2
Enter the anomaly and prepare for the boss fight. Ensure your team is well-equipped, as the Nestbound Bird is not a trivial enemy.

Step 3
Defeat the Nestbound Bird boss. Focus on mechanics and survival while maintaining consistent damage output.

Step 4
Collect the “Tears Beneath the Mask” Arc after defeating the boss. This is part of the reward pool tied to the encounter.

Step 5
Spend 60 Character Pixel to claim the full reward pool. This is a crucial step—without spending this resource, you won’t receive the fragment.

How Nest Guard Fragment is used in ascension
The primary use of Nest Guard Fragment is in Esper ascension, which you access through the character customization interface. When your Esper reaches certain level thresholds, you’ll see an option to ascend—provided you meet all requirements.
Step 1
Open your Esper’s character customization tab. This is where all upgrade and progression systems are located.

Step 2
Check ascension eligibility. You must meet both level and appraisal requirements before proceeding.

Step 3
Gather required materials, including Nest Guard Fragment. At higher levels, multiple rare materials are needed like Colorful Ticket Stub.

Step 4
Submit the materials to initiate ascension. Once completed, your Esper will unlock higher stats and possibly new capabilities.
Why you should always farm boss loots
As you move deeper into NTE, character strength scaling becomes heavily dependent on ascension levels. Without materials like Nest Guard Fragment, your Espers will hit a hard cap, limiting your ability to tackle tougher anomalies and bosses.
This makes the fragment not just useful, but essential for competitive progression. Players aiming for endgame content or efficient farming routes will need a steady supply of these materials.
Nest Guard Fragment is a cornerstone material for advancing your Espers beyond basic limits in Neverness to Everness. By consistently farming the Nestbound Bird anomaly and managing your Character Pixel wisely, you can maintain steady progression. If you focus on both combat efficiency and resource planning, you’ll find yourself ascending your team much faster and tackling harder content with ease.
