Nitsa is a playable character in Neverness to Everness (NTE) who belongs to the Bureau of Anomaly Control as an ETD Reserve. She has been officially announced as part of the game's roster, but remains unreleased and unplayable as of the current version.
Quick answer: Nitsa has not yet been added to the game. She is listed as an upcoming character with no confirmed release date or confirmed stats.

Affiliation and Role
Nitsa serves as an ETD Reserve with the Bureau of Anomaly Control, the primary organization tasked with investigating and containing anomalies—supernatural disturbances and entities that warp reality in the modern city of Hethereau. The ETD squads are the operational units within this bureau, and Nitsa's reserve status suggests she functions as a support member of one of these teams, likely the ETD-6 based on character roster groupings.
Other Bureau members span various squad assignments, from captains leading active operations to specialists handling specific anomaly types. Nitsa's exact combat role and capabilities remain officially unconfirmed.
Current Status and Availability
As of the game's launch on April 29, 2026, Nitsa is not yet playable. She was absent from all beta test phases, making her one of the least-documented characters in the roster. Her rarity (whether A-class or S-class), element type (Anima, Psyche, Cosmos, Incantation, Lakshana, or Chaos), role classification, and Arc compatibility have all been marked as TBA (to be announced) by the developers.
Nitsa is grouped with other unreleased characters, including Alphard, Black Bird, Akane, Illica, Jenson, Shinku, Iroi, Elyms, Lingko, Exe, and Chaos. None of these characters have confirmed release windows or banners. The game's roadmap currently extends through version 1.1, which features Lacrimosa and Chaos, but no official timeline for Nitsa's debut has been published.

What Remains Unknown
Because Nitsa was never included in testing phases, no gameplay footage, ability descriptions, or combat mechanics have been revealed. The community has seen character showcase trailers, teasers, and artwork for various roster members, but Nitsa has had minimal visual exposure compared to launch-day characters. Her weapon type, voice cast, and narrative connections to other Bureau members are all unconfirmed.
Players should avoid making pulls or resource decisions based on speculation about her stats or release timing. Official announcements from Perfect World and Hotta Studio will provide the first concrete details about when she becomes available and what her combat profile looks like.
