BLUE REFLECTION Quartet SUN Squad Tier List (Pre-Launch)
Role rankings for the weakest squad in history—using Second Light combat rules in Quartet's console rebuild.
BLUE REFLECTION: SUN in BLUE REFLECTION Quartet rebuilds the delisted mobile/PC story as a console experience with Second Light’s Timeline combat. You lead the self-described “weakest squad in history” against Testa born from ash, resolving each member’s troubles across twenty-four events. This tier list ranks the eight primary squad Reflectors plus leadership context for Shiho Kasuga using pre-launch role analysis—Ether Recovery kits, Fragment flexibility, and Support bench value—because Quartet tuning is not finalized until after the July 30, 2026 launch. Expect revisions on updates.
Important caveats
- SUN’s roster is smaller and more fixed than Second Light; tier gaps matter less than correct role coverage.
- Quartet balance may differ from the original SUN mobile economy even with Second Light battle rules.
- The Leader (player avatar) inherits Second Light-style center-slot back-attack bonuses—tiers assume you leverage Search Mode openings per combat.
- Cross-title imports in Second Light do not retroactively change SUN saves; learn characters here before they reappear in optional Second Light quests.
Tier definitions
| Tier | SUN context |
|---|---|
| S | Must-invest for efficient clears; heals, break, or Ether Recovery anchor |
| A | Strong primary or bench Orders; minor resource competition |
| B | Playable with investment; better in affinity runs than speedruns |
| C | Niche episodes or late unlocks with limited combat return |
S Tier
Yu Alesia Morisaki — Former squad leader with serious combat profile in series materials. Pre-launch ranking assumes strong attribute coverage and mid-Gear Fragment activation suited to SUN’s shorter chapters. Ideal center-slot candidate when back attacks matter.
Kanna Hoshiya — Cold, precise fighter archetype with burst-friendly skill pacing in Second Light-derived systems. High Ether Recovery on-skill (series pattern) supports fifteen-hit Ether Tide routes against Testa elites.
Shiho Kasuga (Leader) — Protagonist efficiency tier: not always highest DPS, but always worth Talent points because story locks her in active slots. S tier for investment priority, not optional skip.
A Tier
Yukiko Takaoka — Bookish support/healer flex; Dates likely yield Recovery Fragments at Gear 2 thresholds. Bring when chapters spike emotional stress events that parallel harder boss patterns—healing stabilizes combo counts.
Nanaka Azumi — Peppy idol hopeful with Support Orders leaning buffs. A-tier bench value even when not front-line; Order rings complement item cycles in items.
Ayami Ikoma — Self-proclaimed big-sister tank with guard-adjacent kits. A for Timeline stabilization, especially when enemies break combos frequently.
B Tier
Xiao Meiqi — Idol dreamer with offensive skew but slower Gear ramp in pre-launch estimates. Climbs with Ether Recovery Fragments from dedicated Dates; fine for story, slower for optional grind.
Kirara Kuno — Mysterious divine-voice plotline; unique episodes for Reference database more than early combat. B until later events unlock stronger skill lines—see SUN walkthrough timing.
C Tier (situational)
Episode-only allies and support NPCs — Mai, Uta, Ayaka, and Yura Shijou appear in narrative roles; combat investment before finale is optional. C for combat tiering, not story importance.
Duplicate healers when Yukiko suffices — Running multiple Recovery-focused builds without distinct Orders wastes Fragment slots in SUN’s tight grid.
Recommended squad templates (pre-launch)
Story-first template
- Center: Yu or Kanna
- Recovery: Yukiko
- Flex: Shiho or Ayami
- Bench: Nanaka for Orders
Aggressive combo template
- Center: Kanna
- Break: Yu
- Flex: Shiho
- Bench: Nanaka buff Orders
Adjust after you identify recurring Testa weaknesses (Slash vs Shock etc.) using attribute rules in combat. SUN chapters do not always telegraph weaknesses—carry a break specialist and a healer before sacrificing either for duplicate DPS.
Transfer knowledge to Second Light
Characters ranked here reappear as optional Second Light recruits in Quartet. If you bonded with Yu or Kanna in SUN, their recruitment quests in Second Light feel smoother, but mechanical tiers do not import—re-evaluate on the Second Light party tier list because Ao’s roster has different Support math.

Frequently Asked Questions
Quick answers to the most common questions.
Does SUN use the same combat tiers as Second Light?
Combat rules match Second Light in Quartet, but roster size and chapter pacing differ—use this SUN-specific list, not Second Light tiers directly.
Who is the best healer in SUN?
Pre-launch estimates favor Yukiko for Recovery Fragment synergy, with Nanaka as bench Support alternative.
Is the Leader weaker than Yu or Kanna?
Shiho is S-tier for investment priority because story requires her, even if specialists out-damage her in optional content.
Will Quartet change these rankings?
Likely. This list is pre-launch; watch updates for rebalance notes after release.
How many characters should I level in SUN?
Focus on three active Reflectors plus one bench Supporter early. SUN punishes spreading Dates and Talents too thin.
