Esper Zero
"The Appraiser"
Overview
Updated: Apr 29, 2026Esper Zero is the S-Rank Cosmos Solid protagonist of Neverness to Everness. As the only Esper undetectable under the Wertheimer Index, Zero possesses the unique ability to sense and locate Anomaly Nexuses. Players can choose between Male or Female versions. Zero excels as a versatile DPS with strong burst damage and team healing utility.
Skills
Basic Attack: Appraisal - Severance
Channels energy through the weapon, performing up to 5 consecutive attacks that deal Cosmos DMG.

Divide by Zero
Sweeps away the unseen lines connecting the Nexus in a dance of blades. Deals multiple instances of Cosmos DMG to an area.
Rift Blossom
Slashes through space and detonates a rift, dealing 2 instances of Cosmos DMG in an area.
Appraiser

Overview
Esper Zero is the main character of Neverness to Everness — an already-awakened Esper discovered near the core of a major Anomaly incident in New Helios. With no memory of the past and completely undetectable under the Wertheimer Index, Zero serves as the “Appraiser” who can sense and locate Anomaly Nexuses. Players can freely choose between Male and Female versions early in the story (changeable later in settings under the “Others” tab).
Zero functions as a versatile Cosmos DPS with two defining traits: a powerful burst Ultimate with an innate 25% damage bonus, and a passive that provides team-wide healing whenever any active character gains Ultimate Energy. This dual utility makes Zero one of the most flexible characters in the game.
Key Mechanics
Appraiser Passive
| Component | Effect | Details |
|---|---|---|
| Charge Enhancement | HP Restoration | Restores HP equal to 50% of Zero’s Base ATK when any active character gains Ultimate Energy |
| Anomaly Perception | Ultimate DMG +25% | Flat multiplicative bonus to all Ultimate damage |
The healing component triggers on every instance of Ultimate Energy gain across the entire team. In reaction-heavy teams where energy flows constantly, this provides substantial sustain without a dedicated healer.
Rift Blossom (Support Skill)
Rift Blossom deals 2 separate instances of Cosmos DMG, making it one of the best Support Skills for triggering elemental reactions. Each hit counts independently for Esper Cycle purposes, allowing Zero to contribute to reaction chains even while off-field.
Divide by Zero (Ultimate)
The Ultimate deals multiple instances of Cosmos DMG in a wide area. Combined with the innate 25% damage bonus from Anomaly Perception, this creates one of the highest single-window burst outputs among Cosmos characters. Save Ultimate for vulnerability windows or when enemies are Broken for maximum value.
Best Build
Arc (Weapon)
| Priority | Arc | Why |
|---|---|---|
| BiS | The Rain That Shook the World | Highest ATK scaling + Cosmos DMG synergy for burst windows |
| Alt | Day Off | Energy regeneration for faster Ultimate uptime |
| F2P | The Forgotten | Accessible option with solid base ATK |
Cartridge Set
Lost Radiance (4-piece) is recommended for Cosmos DMG amplification that synergizes with Zero’s burst-focused kit.
Alternative: Shadow Creed for general CRIT builds.
Stat Priority
| Slot | Main Stat | Sub-Stats |
|---|---|---|
| Module 1 | ATK% | CRIT DMG > CRIT Rate > Cosmos DMG% |
| Module 2 | Cosmos DMG% | CRIT DMG > CRIT Rate > ATK% |
| Module 3 | CRIT DMG | ATK% > CRIT Rate > Energy Regen |
ATK% is the top priority because it scales both damage output and the passive healing amount simultaneously.
Skill Priority
Ultimate > Skill > Basic Attack > Support Skill
Ultimate receives the highest priority due to the innate 25% damage multiplier making each level-up more impactful.
Best Teams
Blossom Carry Team (Premium)
| Slot | Character | Element | Role |
|---|---|---|---|
| Main DPS | Esper Zero | Cosmos | Burst DPS + passive healing |
| Sub DPS | Nanally | Anima | Follow-up attacks + energy generation |
| Buffer | Sakiri | Incantation | ATK buff + Blossom trigger |
| Support | Jiuyuan | Lakshana | Charged reaction + energy battery |
This team maximizes Ultimate uptime through constant reaction chaining. Switching between Cosmos (Zero) and Lakshana (Jiuyuan) triggers Remora, while Anima (Nanally) and Cosmos (Zero) trigger Blossom for Vita Bud sustained damage.
Burst Window Team
| Slot | Character | Element | Role |
|---|---|---|---|
| Main DPS | Esper Zero | Cosmos | Burst DPS |
| Sub DPS | Chiz | Cosmos | Grain DPS + Cosmos resonance |
| Support | Jiuyuan | Lakshana | Charged reaction trigger |
| Healer | Hathor | Lakshana | Healing + Remora trigger |
Dual Cosmos characters provide elemental resonance. Jiuyuan and Hathor handle Lakshana reactions while Zero and Chiz alternate burst windows.
F2P Accessible Team
| Slot | Character | Element | Role |
|---|---|---|---|
| Main DPS | Esper Zero | Cosmos | Burst DPS + healing |
| Support | Hotori | Cosmos | Time Stop burst + recording |
| Buffer | Haniel | Psyche | ATK buff + Nova trigger |
| Flex | Jiuyuan | Lakshana | Reactions + energy |
Hotori records Zero’s skills for replay during Time Stop, creating massive combined burst windows.
Gameplay Tips
Zero’s standard rotation opens with Support Skill (Rift Blossom) for 2 reaction triggers on entry, followed by a full Basic Attack chain to build Ultimate Energy. Once Ultimate is charged, switch to trigger any pending reactions, then swap back to Zero and activate Divide by Zero during the enemy’s vulnerability window.
The passive healing from Appraiser means Zero can function as a pseudo-healer in teams that generate frequent Ultimate Energy. In Blossom teams where energy flows constantly, this often eliminates the need for a dedicated healer entirely — freeing a team slot for another DPS or buffer.
For overworld exploration, Zero is one of only two characters who can ride a motorcycle, providing faster traversal than standard movement.
