The Sea Sings in My Key
[Single Target]Deals Wind DMG equal to 70% of Robin • Summeretto’s Max HP to one enemy.
Robin • Summeretto is a flexible Remembrance support. She builds up Vibes to bring all three Summer Songbirds onto the field, and from there she buffs the whole team almost on autopilot. Her Ultimate advances the action of the ally you pick and restores their Energy, whenever you want it. She shines in all three endgame modes, so she is well worth pulling.
She fits a huge range of teams: Deviated Chords gives ATK to allies whose ATK is higher than hers and CRIT DMG to everyone else, so she works with both ATK scalers and HP scalers. If you play a Remembrance team built around Castorice, Evernight or Aglaea, she is an even easier pick.
Her ATK buff scales off her Max HP, so put everything into HP, SPD and Energy Regeneration Rate.

Go HP% on the body first, with CRIT DMG as the backup. SPD boots are the standard pick. HP% boots cost her a bit of Energy gain but give your allies a bigger ATK buff. HP% on the sphere and Energy Regeneration Rate on the rope.
In ATK-scaling teams, skip CRIT stats completely and only stack SPD and HP% so her ATK buff is as big as possible. Her own damage is usually pretty weak in teams without memosprite buffs.
Her Ultimate level sets how much Energy your ally gets back. Her Talent sets how much DEF the Zone ignores, and the Memosprite Talent sets the DMG boost during Fever and how much extra DMG enemies take. Leave the Skill and Basic ATK for last.
Deviated Chords is her main buff for the team, so unlock it first. Improvised Blues gives her extra Energy when your team has someone who heals or gives Shields. Rebuilt Harmony adds 50% CRIT Rate to her and the Summer Songbirds.
E1 has the Summer Songbirds record the damage your allies deal, then deal extra True DMG equal to a part of that tally to the enemy with the highest HP, which is great for fights with a main boss and smaller adds. E2 raises the whole team's All-Type RES PEN, lifts her Vibes cap to 70 and gives her 2 extra points the first time an ally makes her gain Vibes in any unit's turn, so she holds more Vibes and her buffs stay higher. E6 gives her a fixed 140 Energy the first time she enters Fever in a battle and at the start of every countdown turn, and lets her store her Ultimate up to 2 times during Fever, so your team sees her Ultimate far more often.
The Summer Songbirds stay on the field the whole time, so every heal or AoE hit has more targets and Castorice gains Newbud faster. You don't have to aim Robin • Summeretto's Ultimate at Castorice. Using it on Hyacine for the Energy is often the better play.
In this full Remembrance team everyone boosts each other's damage in some way, and she buffs both Cyrene and Evernight. A well-timed Ultimate can let Evernight use her Skill twice within one Darkest Riddle consumption, and the percentage-based Energy refund makes Evernight a much stronger main damage dealer.
Himeko • Nova needs a lot of Energy and attacks often, which makes her a great target for the Ultimate. The catch is that Robin • Summeretto can't take actions to use up Himeko • Nova's Assist Skills, so when you advance Himeko • Nova you need to plan the turn order ahead. Welt is currently Himeko • Nova's best teammate.
This team scales on several different stats. Robin • Summeretto turns HP buffs into ATK for Ashveil, which is why Hyacine still fits here, while Mortenax Blade gets her ATK or CRIT DMG buff and hits harder. Mortenax Blade's DEF Reduction and her Zone's DEF ignore work very well together.
She likes having a healer around to trigger Improvised Blues for extra Energy. Hyacine is fast and acts several times per turn, so she stacks Vibes very well.
With the Summer Songbirds always on the field, every heal or AoE hit has more targets, so Castorice gains Newbud faster. That makes her one of Castorice's better teammates.
Her on-demand action advance and percentage-based Energy refund make Evernight a much stronger main damage dealer.
As a Remembrance character, she gets the part of Cyrene's passive meant for Remembrance characters, and she also raises Cyrene's damage.
Her signature Light Cone and some Planar Ornaments give the team SPD, and Aglaea gets a huge ATK buff from her. The action advance and percentage-based Energy refund suit Aglaea's large 360 Energy pool.
An Energy-hungry damage dealer who attacks often, so she is a great Ultimate target. Plan the turn order carefully so all of Himeko • Nova's Assist Skills get used.
He usually plays Sub-DPS and gets her ATK or CRIT DMG buff to hit harder. His DEF Reduction and her DEF ignore work very well together.
She turns HP buffs into ATK for Ashveil, which lets Hyacine join Ashveil teams alongside Mortenax Blade.
Her Skill summons the Summer Songbird Bessie and restores 20 Energy for her. If a Summer Songbird is already on the field, the Skill heals it instead and gives her 6 Vibes. On top of that, she gains 1 Vibe every time an ally attacks, or the first time an ally heals or gives a Shield in any unit's turn, up to 50.
At 6 Vibes Drummie joins automatically, and at 12 Vibes Paddie follows. The more Summer Songbirds on the field, the more DMG enemies take. Once all three are out, her Crowd Control debuffs are dispelled, she enters the Fever state and deploys a Zone. Allies attacking inside the Zone ignore part of the enemy's DEF, and the more Vibes she has, the more DEF they ignore.
During Fever she no longer takes turns and is immune to Crowd Control. The Summer Songbirds act for her and use Chirrup Quartet to hit all enemies, and both her DMG and theirs go up with her Vibes.
A countdown also appears on the action bar with an initial SPD of 140. Every time it takes its turn, she loses 50% of her current Vibes (at least 12). When Vibes hit 0, the Summer Songbirds disappear and Fever ends. That means your team has to generate enough Vibes between countdowns, and you should time your bursts around how many Vibes she has. If the Summer Songbirds leave the field, her action advances by 50% so she can bring them back quickly.
Her Ultimate costs 140 Energy. It advances one ally's action (not her own) by 100% and restores Energy based on a percentage of that ally's Max Energy. That ally gets Special Guest for 2 turns: each time they or their summon attack, she gains 2 extra Vibes, but they can't advance other allies' actions. It works especially well on characters who attack a lot outside their turn or have a memosprite attacking for them.
The Ultimate gives no special buff to the ally you pick, because all her buffs already apply to the whole team. So you are free to choose: push a Sub-DPS or another support ahead of your main DPS, or top up Energy for a teammate's key Ultimate.
With Deviated Chords, whenever an ally makes her gain Vibes: if that ally's ATK is higher than hers, they gain ATK equal to (16% + 0.4% per Vibe) of her Max HP. If not, they gain (40% + 1.5% per Vibe) CRIT DMG instead. The buff lasts 2 turns. This is why she works with both ATK scalers and HP scalers, and why you should stack HP on her.
Deals Wind DMG equal to 70% of Robin • Summeretto’s Max HP to one enemy.
Summons the memosprite “Summer Songbirds” Bessie. If any member of the “Summer Songbirds” is already on the field, restores their HP by an amount equal to 125% of “Summer Songbirds'” Max HP, and gains 6 Vibes.
Advances the action of one designated ally character (excluding Robin • Summeretto) by 100% and regenerates a fixed amount of Energy equal to 24% of their Max Energy. Then, grants them the “Special Guest” effect.

Memosprite “Summer Songbirds” has an initial Max HP equal to 70% of Robin • Summeretto’s Max HP and an initial SPD equal to 180% of Robin • Summeretto’s SPD. When an ally target uses an attack, or when they provide healing or Shield for the first time in any target’s turn, Robin • Summeretto gains Vibes by 1 point, capped at 50. While “Summer Songbirds” Bessie is on the field, if Robin • Summeretto’s Vibes is 6 or higher, immediately summons “Summer Songbirds” Drummie, and if Vibes is 12 or higher, immediately summons “Summer Songbirds” Paddie. When all “Summer Songbirds” take the stage, dispels all Crowd Control debuffs inflicted upon Robin • Summeretto and the “Summer Songbirds”, starts the “Fever” state, and deploys a Zone. When ally targets deal DMG within the Zone, they ignore a percentage of enemy targets’ DEF equal to (17.5% + Vibes × 0.5%).
While in the “Fever” state, Robin • Summeretto and the “Summer Songbirds” are immune to Crowd Control debuffs. Robin • Summeretto will not enter her turn until the “Fever” state ends.
