Mitsuki is the internal beta-testing name for the character now released as Aurelia in Neverness to Everness. The character appeared as Mitsuki during earlier closed beta tests, then was renamed to Aurelia ahead of the global launch on April 29, 2026. All official materials, trailers, and database entries released since the Co-Ex Test use the name Aurelia exclusively.
Mitsuki is a Japanese name meaning "beautiful moon" (美月). The transition to Aurelia, derived from the Latin word for "golden," signals a shift from East Asian naming conventions to a classical Western-derived name. The change could reflect a localisation decision, a rebranding of the character's visual or thematic direction, or a deliberate lore choice in which Mitsuki is treated as a stage name or alias from her band-member days.
During the closed beta tests, players could find the character known as Mitsuki strolling through Tamamochi Street in Hethereau as a wandering NPC. She was not playable during the beta but was visibly present in the open world, following a pattern the developers use to introduce upcoming characters organically before their official gameplay debut. The character was confirmed as A-Class Psyche during the same period.
This NPC presence helped build anticipation for the playable launch version. Beta participants who interacted with the Mitsuki NPC frequently asked when she would become playable, and the developer response was eventually to confirm her launch-day playable status under the renamed identity Aurelia.
Mitsuki / Aurelia has confirmed connections to several launch-roster characters, with one in particular forming the centrepiece of her launch backstory.
Character | Relationship | Notes |
|---|---|---|
Former bandmate | The Launch Preview Special Program confirmed that Aurelia and Akane Rin were members of the same band before the start of the game's main story. The band's name (LINES) connects the two characters' shared past. | |
Music-scene contemporary | Akane is the launch playable counterpart to Akane Rin's full name. Aurelia's bond progression interacts with the broader Akane / Akane Rin music-scene storyline. | |
Bureau introduction | Aurelia is unlocked via the Day 3 launch login event for Esper Zero protagonists; the meeting cutscene introduces her into the player's home base. | |
Visiting Esper | As a Day 3 free unlock, Aurelia joins the player's roster from the Eibon home-base side rather than via a paid banner. |
Aurelia's affiliation is best understood through three overlapping framings: her former band identity, her A-Class Psyche role inside the Esper roster, and her relationship to the Bureau and Eibon factions.
LINES band (former). Aurelia and Akane Rin were members of LINES before the events of the launch storyline. The band is no longer active in launch-window content, and both former members have moved into Esper roles in the Bureau / Eibon-aligned Hethereau ecosystem.
Bureau-adjacent. Aurelia is not a confirmed full-tier Bureau member like the ETD platoon Espers (Baicang, Skia, Lacrimosa, EXE, Linko). Her Bureau interactions are framed as an associate-level connection rather than a platoon assignment.
Eibon-adjacent. As a Day 3 free unlock, Aurelia is introduced through the Eibon-anchored launch login flow rather than through Bureau directives. She is not a permanent Eibon staff member like Hotori, Adler, Edgar, Daffodil, Nanally, or Sakiri, but she is friendly with that crew during launch-window content.
Psyche element specialist. As an A-Class Psyche character, Aurelia's role is roster-functional: she can fill a budget Psyche slot for Stain and Nova reactions, sitting between the free unlock Haniel and the S-Class healer Fadia.
Three plausible reasons for the name change appear in available context:
Localisation standardisation. Aurelia translates more cleanly across languages than Mitsuki, which carries specific Japanese cultural weight that may not match the character's intended global identity.
Visual or thematic refresh. The character may have undergone a design iteration between beta and launch, with the new name signalling the new look. Other launch characters (notably Hotori) also received design refreshes between beta and launch.
In-universe alias framing. Aurelia's background as an ex-band member opens the possibility that Mitsuki was her stage name during the band's active period, and Aurelia is her reclaimed identity afterward. This reading would make both names canonical within the story.
Official materials have not stated which of these is the actual reason. The cleanest framing is to treat Mitsuki as the historical beta name and Aurelia as the canonical launch name, with the in-universe interpretation left open until additional lore is published.
As of the global launch, Mitsuki does not appear in any official live-service materials. Older beta-era community guides, datamines, and wiki snapshots may still reference the name, but these reflect outdated information. Players researching the character should use Aurelia for any post-launch reference.
Some retrospective coverage of the beta tests still mentions Mitsuki in passing, particularly when discussing the Co-Ex Test beta where the NPC was active. This historical use is appropriate when describing the beta-era state of the game; it should not be carried forward into descriptions of current content.
Aurelia is confirmed as A-Class Psyche and is distributed free as part of the launch login event, with 12 Solid Dice and a Stellar Veil Arc bundled into the same campaign. Her Affinity Bond cap is set to Tier 2 for the duration of Version 1.0, which is lower than the standard 10-tier cap on most other companions; the cap is expected to lift in a later patch as her dedicated bond content rolls out.
Players returning from the beta-era state should expect the launch Aurelia to look and play differently from the wandering Mitsuki NPC. The kit, weapon, story role, and dialogue are all part of the post-rename launch package; the Mitsuki NPC was pre-playable presence material and is not the same character implementation.
Use "Aurelia" for any current reference. Mitsuki is the historical beta name and is not used in launch materials. The Aurelia article is the canonical post-launch entry.
Watch for in-game lore references. If Aurelia's character story confirms an in-universe reason for the name change, the connection between the two names will be made explicit in companion dialogue or during her bond-quest progression.
Treat beta-era guides cautiously. Builds, kit details, and stat numbers tied to the Mitsuki name predate the launch implementation and may be inaccurate. Use only post-launch sources for current build information.
Pair the rename with the LINES-band lore. The Akane Rin / Aurelia former-bandmate framing is the cleanest way to link the two names within the story; the in-universe stage-name reading fits the band-member background especially well.
