Quick Guide
  • Stella Sora character list: Playable units are called Trekkers, paired with equippable Runic Discs.
  • Team size: Combat uses a three-Trekker squad, so role coverage matters more than rarity.
  • Core roles: Main damage dealer, support/buffer, and frontline or utility define most teams.
  • Recruitment: Trekkers and Runic Discs come from separate recruitment banners with distinct rules.
  • Best approach: Judge a Trekker by role, synergy, and stage performance, not rarity alone.

How the Stella Sora Character System Works

In Stella Sora, the playable character list is organized around Trekkers, the heroes you recruit and send into the world of Nova. Each Trekker fills a combat role inside a three-member active team, and their performance is shaped further by Runic Discs, the companion equipment pieces recruited through their own banners.

Stella Sora launched globally on October 19, 2025 from developer Yostar, and the roster continues to expand through version updates such as 2.0. Because the roster grows every patch, the character list below is organized by role and function rather than a fixed set of names, so it stays useful as new Trekkers arrive.

Video Highlights:

The character system splits cleanly into three layers:

| Layer | What It Is | How You Get It | | Role | A Trekker's combat function (damage, support, frontline) | Fixed per Trekker | | Trekker | The playable unit with active skills | Trekker recruitment banners | | Runic Disc | Equip piece that reinforces a Trekker's combat pattern | Runic Disc recruitment banners |

Read the Role First

When evaluating any new Trekker from the character list, identify its role before checking rarity. A B-tier role you need beats an S-tier unit that overlaps with your existing carry.

Stella Sora Character List by Combat Role

Every Trekker in the game fits into one of the core role archetypes below. Use this breakdown to understand where each character on your roster belongs.

Primary Damage Trekkers

  • Main damage output for the team
  • Benefits most from core skill levels
  • Pairs with offensive Runic Discs
  • Best for bosses and priority targets

Support and Buffer Trekkers

  • Provides buffs, healing, or energy
  • Values uptime and cooldown support
  • Amplifies the main carry's rotation
  • Best in long encounters

Frontline and Utility Trekkers

  • Shields, taunts, or crowd control
  • Creates safe attack windows
  • Defensive equipment focus
  • Best against heavy-pressure waves

The tier framework below explains how the community and guides typically sort the character list by practical value:

| Tier | Profile | Team Value | Best For | | S | Core carries and universal enablers | Can anchor a team with limited support | Progression, hard stages, first long-term team | | A | Strong specialists (burst, control, elemental) | High value but needs deliberate team building | Focused teams and favorable matchups | | B | Reliable progression choices | Fills missing roles effectively | Early to mid-game, temporary teams | | C | Niche or investment-heavy units | Requires specific content or synergy | Experimentation, specialized encounters |

Avoid Rarity-Only Rankings

Sorting the character list purely by rarity is the most common team-building mistake. Many A and B-tier Trekkers outperform higher-rarity units when their role coverage and Runic Disc pairing fit the encounter.

Recruiting Characters: Trekkers and Runic Discs

Characters enter your roster through two separate recruitment systems, each with its own currency, guarantee rules, and banner schedule.

| Banner Type | Category | Currency | Key Rule | | Trekker Recruitment | Character units | Trekker recruitment currency | Check official notice for guarantee and featured-character rules | | Runic Disc Recruitment | Equipment pieces | Runic Disc recruitment currency | Separate guarantee and featured-disc rules apply | | Limited Resources | Tickets and exchange currency | Varies by campaign | Spend before the expiry shown in-game or in the announcement |

Carryover Differs by Banner

Do not assume guarantee progress or exchange currency carries over between banners. Trekker and Runic Disc banners can follow different carryover rules, so always check the specific official announcement before spending limited tickets.

Follow these steps when a new banner opens:

1

Read the Official Announcement

Confirm the banner start and end times, featured Trekkers or Discs, and guarantee rules from the official news page.

2

Check the Schedule Fit

Compare the banner window against your resource total. Decide whether you can reach the guarantee comfortably before it ends.

3

Evaluate Role Coverage

Ask whether the featured character fills a gap in your current three-Trekker team before pulling.

4

Spend Limited Tickets Before Expiry

Use banner-specific tickets and exchange currency before their stated expiration, since carryover is not guaranteed.

Building Your First Team from the Character List

With only three active slots, your first team should combine a dependable damage source with survivability and utility. These three archetypes convert the character list into practical squads:

| Team Archetype | Slot 1 | Slot 2 | Slot 3 | Best For | | Balanced Core | Main DPS | Attack/energy support | Frontline or shield | General progression, bosses | | Elemental Reaction | Primary elemental DPS | Secondary elemental applier | Control or support | Element-sensitive encounters, waves | | Control and Sustain | Damage dealer | Crowd-control specialist | Healer or shielder | Elite groups, interruption-heavy content |

When a preferred element or role is missing from your roster, substitute any Trekker with the same functional role rather than waiting for a specific unit.

Upgrade Order Matters

Invest in your primary damage dealer first, keep the rest of the team close enough in level to survive, and only add secondary utility upgrades once the main rotation is stable.

First Team Milestones:

  • Lock in one primary damage Trekker and max its core skill
  • Add one support, healing, or shielding role
  • Fill the frontline or utility slot
  • Equip Runic Discs that match each Trekker's combat pattern
  • Test synergy on normal stages before heavy investment
