BLUE REFLECTION Quartet Tier Lists

Tier lists for BLUE REFLECTION Quartet now reflect launch-week data as of August 2, 2026. Gust has added eight optional party members to Second Light and rebuilt SUN with Second Light combat, so role overlap and Talent costs may still shift once players log hundreds of hours and patches land. Treat every tier here as a living ranking, then revise against live clears and patch notes on updates.

Why launch-week rankings still help

Even without final DPS spreadsheets, Reflector squads follow recurring patterns: someone must stabilize Timeline tempo with heals or Slow, someone must spike Gear for Ether Tide setups, and someone must break attributes or Knockdown windows. First-week clears and series history tell us which characters shipped with stronger Ether Recovery kits, better Support Orders, or Fragment grids that activate at Gear 2 instead of Gear 5. That knowledge saves Talent points before you commit to Quartet-exclusive guests who duplicate a core role.

We separate rankings by title because saves do not cross games inside the launcher:

• BLUE REFLECTION Supports tier list — Hinako’s bond-gated Support roster; start here if you are still in the 2017 school sim.
• Second Light party tier list — Ao’s campaign plus RAY/SUN imports in the Quartet remaster.
• SUN squad tier list — The rebuilt console story with a fixed leadership squad and tighter roster math.

Original BLUE REFLECTION (2017) does not use the Gear/Fragment grid meta; power comes from bond-gated growth and Overdrive chains. The dedicated Supports tier list covers Hinako’s trio planning instead of forcing misleading letter tiers against Ao’s party.

How tiers are judged (launch-week criteria)

Each character is scored on five axes weighted toward Second Light/SUN combat:

1. Ether Recovery contribution — Personal speed and party-wide buffs that reach Gear 4–5 before boss phase shifts.
2. Role flexibility — Can the unit heal, break, or buff if Fragments and Talents are repointed?
3. Fragment synergy — Does their Date pool favor early Active Gear pieces?
4. Support Order value — Bench utility when not in the active trio.
5. Quartet exclusives — New episodes, recruitment quest cost, and Reference database ties—not raw power alone.

Letters (S / A / B / C) express relative priority within a title, not absolute power across the whole compilation. A SUN A-tier healer is not automatically stronger than a Second Light B-tier DPS when Gear caps differ by chapter.

Honest limitations

• SUN and Second Light letter tiers may still shift as launch-week data accumulates and Gust ships balance patches.
• Quartet tuning may differ from standalone Second Light or delisted SUN mobile numbers you remember.
• Talent and Fragment investments can elevate low-tier story guests above high-tier bench warmers on your account.
• Patch notes can reorder tiers overnight—subscribe to the updates hub rather than treating this page as permanent gospel.
• Spoiler-free rankings avoid late-story skill names; tiers assume standard progression without finale-only mechanics.

Using tier lists with other guides

Pair rankings with mechanical depth:

• Combat systems for Ether Tide, Knockdown, and back attacks.
• Builds for Fragment grids and skill loadouts that implement tier advice.
• Walkthrough hub for recruitment timing—some Quartet guests arrive too late to justify S-tier investment on a first clear.
• Review hub if you are deciding whether to play SUN before Second Light for roster familiarity.

Speedrunners and completionists should also open the playtime planner—tier chasing every optional recruit extends campaign length beyond the seventy- to eighty-hour collection estimate.

Post-launch maintenance

Quartet is live, and we revise tiers using community clear data, boss turn counts, and any Gust statements about SUN rebuild modifiers. Until patches stabilize, use these lists to ask better questions (“Do I need two healers in SUN Chapter 12?”) rather than to dismiss characters you enjoy for story reasons. Emotional resonance is half the series’ design; tiers only cover the combat half.
