NIKKE Yukiko Amagi Build: Burn Code Attacker and Healer

Yukiko Amagi arrives on 20 August as a Burst 3 Fire Code Attacker wielding an MG called Crimson Bloom, and her defining trait is one NIKKE rarely offers: she is an Attacker who heals. Her Persona, Konohana Sakuya, restores HP to the entire squad every three seconds from the start of battle, continuously, without occupying a support slot. On top of that she runs a large distributed damage profile that scales dramatically inside Burst — and she exists to make Makoto (Queen) better. The two are being positioned as the core of Burn-code Solo Raid setups. Here's her full kit, how to build her, and whether she's worth your Gems.

The basics

• Class: Attacker
• Burst: Stage 3
• Code: Fire (Burn)
• Weapon: MG — Crimson Bloom
• Persona: Konohana Sakuya
• Banner opens: 20 August

One caveat before the numbers: the values below come from the published skill data at level 10, and Shift Up's own skill demonstration carried a note that skills may still change and that the footage was recorded in a beta environment. Verify against the in-game skill screen once she's live.

What she actually does

Constant squad healing. Konohana Sakuya is a continuous effect that cannot be removed. Every three seconds it applies Media, restoring HP equal to 5.7% of Yukiko's final max HP to all allies. This runs from the start of battle and re-activates when Full Burst ends.

That's the part that changes team-building. Sustain in NIKKE normally costs you a slot; here it comes attached to a damage dealer.

Distributed damage as her main output. Her Burst deals 1,258.79% of final ATK as distributed damage — the same damage type Makoto is built around, which is not a coincidence.

Self-amplification inside Burst. While her strengthened state is active she gains Fire Amp: Distributed Damage ▲ 90.01%, continuously and unremovably, until Full Burst ends. Entering Burst Stage 3 also grants her Elemental Advantage Attack Damage ▲ 48.15% for 10 seconds.

Upgraded healing during Burst. The strengthened state swaps Media for Mediarama, keeping the three-second cadence.

Defensive scaling against her weakness. Scarlet Protection reduces damage taken from Water Code enemies by 17.95%, continuously. Fire is weak to Water in NIKKE's code triangle, so this partially offsets her natural disadvantage.

The "1 More" mechanic

This is the collaboration's signature interaction, and it's a direct Persona reference.

When 1 More takes effect, Yukiko grants Follow Up: ATK ▲ 80.25% of her own ATK for 25 seconds to all standard Burst 3 allies in the Persona state — excluding herself.

Two things to unpack there. The buff scales off Yukiko's ATK, not the recipient's, which means investing in her attack stat directly raises your other damage dealers' output. And it applies to allies in the Persona state, which is the collaboration's shared mechanic — meaning the Persona units are explicitly designed to be run together rather than distributed across separate teams.

Twenty-five seconds is a long buff window by NIKKE standards, comfortably outlasting a Full Burst rotation.

Yukiko and Makoto

The pairing is the point.

Makoto (Queen) is a Burst 3 Fire Code Attacker using a shotgun, whose core damage also routes through distributed damage, supported by her Persona Johanna granting continuous Elemental Advantage Attack Damage and DEF bonuses.

Both are Burn code. Both are Burst 3. Both scale on distributed damage. And Yukiko's Follow Up buff specifically targets standard Burst 3 allies in the Persona state — which describes Makoto exactly.

Community assessment ahead of release is that Makoto's ceiling rises once Yukiko is available, and that the pair forms a core Burn-code setup for Solo Raid scoring. If you pulled Makoto when the collaboration opened on 13 August, Yukiko is the unit that completes her.

Building her

ATK is the priority stat, and unusually, it isn't only for her own damage. Because Follow Up scales off Yukiko's ATK when buffing your other Burst 3 units, every point of attack on her pays out twice — once through her distributed damage, once through the buff she passes on.

Max HP matters more than usual for an Attacker. Her healing is calculated as a percentage of her final max HP, so HP investment directly improves squad sustain. That's a genuinely different Overload priority from a standard damage dealer.

Overload recommendations, in rough order:

• ATK — feeds both her damage and her team buff
• Max Ammunition Capacity — standard for MG users, since uptime is everything on a machine gun
• Charge Damage / Elemental Damage as available

For Cube selection, options that improve reload or sustained fire suit MG users, though the community consensus for her specifically will take a week or two to settle after release.

Should you pull?

Yes, if you own Makoto. The two are designed as a unit, and running Makoto without Yukiko leaves a substantial portion of her ceiling unreached.

Yes, if you take Solo Raid or Union Raid scoring seriously. A Burn-code pairing offering both high damage and built-in sustain is unusually stable for raid content, where surviving the full timer matters as much as burst output.

Yes, if your roster is short on Fire Code damage. She covers a code slot and a sustain slot at once.

And there's a scarcity argument. Collaboration units run on licensing agreements rather than the developer's own schedule, which makes reruns unpredictable. If you want her, this window is the realistic one — securing at least one copy is the standard advice for collab Nikkes.

Consider skipping if your Gems are committed elsewhere and you don't own Makoto. Yukiko is strong standalone but considerably stronger as half of a pair, and buying into the pair mid-collaboration is expensive.

Don't forget Aigis

Worth mentioning because she costs nothing: Aigis is the collaboration's SR-grade, Burst 2 Support, obtained free through event participation rather than gacha.

Her 20-second Burst cooldown means she can operate solo in the Burst 2 slot without a partner, and her Burst provides an attack buff. For newer Commanders joining through this collaboration, she's a genuinely useful free unit rather than a token giveaway.

Our Persona roster breakdown covers all three characters and the rarity split that decides your budget.

Before the 20th

• Bank your Gems and Advanced Recruit Vouchers. Limited banners award mileage tickets toward a guaranteed pull, and that threshold is what your saving should target.
• Check whether you have Makoto. It changes the calculation entirely.
• Clear the event content for Aigis, since she's free.
• Verify her skill values in-game on release, given the beta-environment caveat on the published data.

Build the squad she completes

A paired damage core only works when the rest of the squad — Burst 1, Burst 2 and the gear behind them — is developed enough to support it.
