Every revealed Stella Sora Trekker with the element, role and faction published in official sources, plus the banner history and story context that decides where each one fits.
Introduction
The Stella Sora roster is organised around Trekker profiles rather than a flat list. Every Trekker belongs to a faction or guild documented on the official site — from the New Star Guild the player joins through to the Grace Imperium, United Harvest and the Ashwind Clan — and carries a stated role where Yostar has published one. The roster spans two rarity bands, ★5 and ★4, with ★5 units headlining limited banners and ★4 units rotating onto rate-up alongside them. This section collects what the official sources actually state about each Trekker: element, role, faction and the context that decides where they fit, and it marks a field as unknown rather than filling the gap when Yostar has not published it.

Trekker Profile Highlights
S
Firstlight Noya
★5 Lux Vanguard — captain of the Filanis Night Watchers
Official ProfileDocumented on the official roster as the Captain of the Filanis Night Watchers with Lux as her element and Vanguard as her role. She was released as an exclusive ★5 Trekker with the Version 2.0 first-anniversary update and fights with the greatsword Daybreak and the longsword Dawn.
Where She FitsThe primary damage slot in a Lux squad. Because the Vanguard role is officially defined and the faction is named, her placement does not rest on an assumed role label — the only variable is whether you were playing during the limited window.
Story ContextA Filanis Night Watcher captain is a command position rather than a freelance one, which distinguishes her from the New Star Guild members who make up the player's immediate circle. Note that she shares a name with the guild member Noya but is a separately documented unit.
S
Otoha
★5 Umbra Versatile — amplification and area damage
Official ProfileDescribed by Yostar as a mysterious and elegant top-tier ninja, and labelled an Umbra-Element Versatile Trekker. She is built to amplify Umbra allies' damage and to finish fights with area attacks rather than sustained single-target output.
Where She FitsBecause she is Versatile rather than Vanguard, she can flex out of the primary damage slot — the only official flexibility the roster provides. That makes her one of the few units who can hold a support position in a squad built around a different primary carry.
Story ContextHer official description emphasises mystery and elegance rather than a faction affiliation, and no organisation is named for her on the roster. She is best understood through the Umbra teams her amplification enables rather than through a guild allegiance.
S
Shia
★5 Lux Vanguard who fights through drones
Official ProfileYostar states that Shia serves as a Vanguard with Lux-elemental abilities, and that she fights using the drones Snow Rabbit and Night Rabbit. The drone detail is the distinguishing part of her profile: a single slot producing multiple damage sources.
Where She FitsShe competes directly with Firstlight Noya for the Lux Vanguard slot, which is useful information for a player who missed the limited banner — the element retains a documented primary damage option either way.
Story ContextOfficially described as a bunny girl from a coastal town, a background with no faction attachment. Her value in a roster context is that she makes Lux viable without a limited recruit, which matters more for account planning than for lore.
A
Firenze
★5 Umbra executive of United Harvest
Official ProfileListed on the official roster as the elegant yet formidable senior executive of United Harvest, and named in official announcements as a ★5 Umbra Trekker. She headlined a rerun on the limited banner, which is a useful signal about how the player base values the unit.
Where She FitsShe is normally paired with Otoha in an Umbra squad, where the amplification Otoha provides applies to her output. Treated as a pair rather than as two separate investments, the element becomes one of the stronger options in the game.
Story ContextUnited Harvest is a named organisation rather than a guild, and her title places her in a senior commercial role. Alongside the Grace Imperium's Dusk Arbiter and the Ashwind Clan's founder, she is part of the roster's institutional rather than adventuring side.
B
The New Star Guild Core
Amber, Noya and Iris — the player's own guild
Official ProfileAll three are documented on the official roster as members of the New Star Guild, the group the player joins as the Tyrant. Their profiles carry no element or role statement, which is why those fields read as not stated rather than being filled in.
Where They FitThey are the Trekkers a new account is most likely to hold, so their practical role is carrying the opening hours until a first ★5 arrives. They have no shared element identity, so no Record supports them efficiently and they should be replaced once an element can be committed to.
Story ContextThe guild is the narrative anchor of the opening: the prologue is framed around it and it is what the player belongs to before any other organisation becomes relevant. Note that the guild member Noya and the limited Trekker Firstlight Noya are separately documented entries.
Chaton
rareWhite Cat Troupe sniper
Official ProfileThe official roster gives her title as Sniper of the White Cat Troupe's Third Squad, placing her in a mercenary organisation rather than a guild. No element or role is stated for her in the official material, so those fields are left open here rather than inferred from her title.
Where She FitsThe White Cat Troupe framing suggests a paramilitary unit rather than an adventuring guild, which is a different context from the New Star Guild members the player joins. Without a published element, she cannot be matched to a committed team on paper, so the practical approach is to evaluate her in-game before building around her.
Story ContextHer title is the most specific thing published about her, and it identifies a squad number rather than an individual role. That level of detail about an organisation is typical of the official roster pages, which describe a unit's place in the world more often than they describe their combat function.
Gerie
rareDusk Arbiter of the Grace Imperium
Official ProfileListed as the Dusk Arbiter of the Grace Imperium, a title that names both an institution and a judicial-sounding office. The Grace Imperium is one of the larger powers represented on the roster, and Gerie appears in official announcements among the ★5 Trekker headlines, including as a Terra Vanguard in one notice.
Where She FitsWhere an official notice names the role, the placement is straightforward; where it does not, the element and role should be treated as provisional. Her institutional title makes her part of the roster's political layer alongside United Harvest and the Ashwind Clan rather than the adventuring one.
Story ContextAn arbiter associated with dusk is a ceremonial or judicial framing rather than a combat one, which fits the pattern of the official profiles describing what a Trekker does in the world. That framing matters for expectation-setting: a title like this says nothing about damage, and the game publishes no multipliers that would.
Minova
rareFounder and leader of the Ashwind Clan
Official ProfileDocumented as the founder and leader of the Ashwind Clan, and named in official announcements as both a Lux Versatile and an Ignis Versatile Trekker across different notices. That dual listing is worth reading carefully: the same character name appears attached to two different elements in different official posts.
Where She FitsThe Versatile label makes her one of the units that can flex out of the primary damage slot, which is the official flexibility the roster provides. Because the element differs between official notices, confirm which version you are recruiting before assuming she fits the element team you have built.
Story ContextAs the founder of a clan she sits at the head of an organisation rather than inside one, which is a different position from the guild members and the corporate executives elsewhere on the roster. Her clan is one of the few named kinship structures in the world material.
Fuyuka
rarePetal Bloom member and Ignis headline
Official ProfileNamed in an official announcement as a new ★5 Ignis Trekker and listed on the roster as a Petal Bloom member. The same notice pairs her with an Ignis Disc, which is the standard version shape — an element receives a Trekker and a Disc in the same window rather than separately.
Where She FitsAn Ignis headline is worth noting for accounts that have not committed to an element, because the pairing of a Trekker and a Disc in one window is the cheapest way to stand up a new element team. The version notice itself is the signal that Ignis is being supported at that moment.
Story ContextPetal Bloom is a named group with more than one member on the roster, which makes it one of the clearer affinity clusters in the world material. Note that Fuyuka and Freesia are separate characters despite the similar names and sit in different elements.
Freesia
rarePost Haste courier — an Aqua unit, not to be confused with Fuyuka
Official ProfileDocumented on the roster as a courier of the Post Haste post office. Post Haste is a named mail service whose leader, Donna, also appears on the roster, which makes it one of the organisations with more than one documented member.
Where She FitsFreesia belongs to Aqua while Fuyuka, whose name looks similar, belongs to Ignis — so the two sit in different element pools and cannot be substituted for one another. Confirm which one you hold before planning an element team, because the mistake sends the Disc investment to the wrong squad.
Story ContextConfusing Freesia with Fuyuka is one of the more common roster-reading errors, and it is a purely textual mix-up rather than a lore question. The official element listing is the reliable way to tell the two apart, and it is worth checking rather than assuming from the name.
Core Mechanics
Reading the Stella Sora roster is mostly a matter of knowing which fields are official and which are community inference. Yostar publishes each Trekker's name, a title or guild position, and in many cases an element and a role, and those statements are the only durable facts about a unit. The two role labels the game actually uses are Vanguard and Versatile, and rarity runs across ★5 and ★4, with ★5 units headlining limited banners and ★4 units rotating onto rate-up beside them. Faction is the third axis: the New Star Guild is where the player starts, while United Harvest, the Grace Imperium, the Ashwind Clan, the White Cat Troupe and the Filanis Night Watchers represent the wider world. Where an official source has not stated an element or role, this section leaves the field open instead of guessing.
Advantages
The roster is unusually well documented for a live-service RPG, because the official site carries a profile page per Trekker with a stated title and, for many units, an element and a role. That makes it possible to plan an account around published facts rather than around secondhand summaries: you can see which Trekkers share an element before committing, which ones carry the Versatile label that lets them flex slots, and which organisations the roster is actually built from. Because the game does not run cross-element reactions, faction and role are more useful organising principles than damage tables would be, and they are the fields the developer has chosen to publish.
Challenges & Weaknesses
The gaps in the official profiles are the main limitation here. Several Trekkers have a faction and a title but no stated element or role, so a reader who wants a complete table cannot have one, and any site that presents a fully filled roster is inferring rather than reporting. Availability is the second problem: the strongest documented units arrive on limited banners, so the roster a guide describes and the roster a new player can actually field diverge significantly. Rarity, meanwhile, is only a band — ★5 and ★4 tell you where a unit sits in recruitment, not how much they contribute, and Yostar publishes no multipliers that would settle the question.
Frequently Asked Questions
How many Trekkers are in Stella Sora?+
The official site documents twenty-nine Trekker profiles, and a small number of additional characters appear in official announcements without a full roster page. Because Yostar adds units on its version cadence, the number changes over time, so treat any fixed figure as a snapshot taken when the page was written.
What roles do Trekkers have?+
Yostar officially uses two role labels: Vanguard and Versatile. A Vanguard occupies the primary damage slot, while a Versatile unit can flex between the damage slot and a support position. Terms like tank, healer, DPS or support are community shorthand rather than official terminology in this game, so advice phrased that way will not match any label shown in-game.
Are Firstlight Noya and Noya the same Trekker?+
No. Both appear as separate entries in the official material: Noya is documented as a member of the New Star Guild, while Firstlight Noya is the exclusive ★5 Lux Vanguard released with the Version 2.0 first-anniversary update and is captain of the Filanis Night Watchers. Their roles in a squad are entirely different.
Why do some Trekkers have no element listed?+
Because Yostar has not published one for them. The official profiles state an element for some units and give only a faction and title for others, so this wiki marks those fields as not stated rather than filling them in. A complete element table for the roster cannot be produced from official sources at present.
Quick Tips
💡Check whether a Trekker's element is actually published before planning around them. Several official profiles give only a faction and a title, so a squad built on an assumed element may not be supportable by the Record you invested in — the field is genuinely unknown, not merely unlisted here.
💡Use the Versatile label to decide which slot a unit can flex into. Only Vanguard and Versatile are official roles, and Versatile units are the only ones that can move out of the primary damage position, which makes them the flexible pieces in a three-slot squad rather than interchangeable damage sources.
💡Distinguish the guild members from the limited headlines when you read the roster. Noya and Firstlight Noya are separate official entries with different roles and factions, and treating them as one unit leads to planning an account around a Trekker you are not actually fielding in any of your squads.
💡Expect the strongest documented units to sit on limited banners. Availability rather than published power is usually what separates the roster a guide describes from the roster a new account can field, so build around what you actually hold instead of what the tier list happens to rank highest. Planning around what you hold also prevents the common trap of reserving resources for a unit that never returns to a banner.
💡Treat rarity as a recruitment band rather than a power rating. ★5 and ★4 describe where a Trekker sits in the banner structure, and Yostar publishes no damage multipliers, so a ★4 unit inside a well-supported element team can outperform a ★5 unit that has no Record built behind it at all.
