Esper Zero is found near a major Anomaly incident in New Helios and is suspected of ties to The Circle, but later loses all memory of their past, leaving their origin unknown. Due to this mystery and unstable status, Zero is placed under strict observation at Groth Island's Jail of Hethereau.
Uniquely, Zero is undetectable by the Wertheimer Index and is known as the “Appraiser,” with the ability to sense anomalies and quickly locate their Nexus, making them a key asset in handling anomaly incidents.

Cafe Profit Tips for Esper Zero Players
Esper Zero helps improve cafe profits indirectly by speeding up farming and daily progression in Neverness to Everness.
Key optimization tips:
- Prioritize passive income upgrades first: Invest early cafe earnings into production boosts, staff efficiency, and resource generation rather than cosmetics or low-impact upgrades.
- Use Zero for fast daily farming routes: His quick-swap burst style makes him ideal for clearing commissions, material nodes, and open-world events efficiently, saving time while increasing daily yield.
- Convert combat speed into economic advantage: Faster dungeon clears and farming cycles mean more cafe resources per session, accelerating long-term progression.
- Reinvest profits strategically: Focus on upgrades that increase output multipliers (production speed, customer flow, and efficiency scaling) instead of one-time rewards.
Over time, this creates a compounding effect where Esper Zero’s combat efficiency directly improves your cafe’s passive income growth.

His strength comes from enabling fast Esper reactions, improving rotation flow, and fitting into multiple team types rather than relying solely on raw damage. Overall, Esper Zero is a safe, long-term investment and one of the most reliable free units in the game.
