Fire5★Released: 14/07/2026 · v4.4 Himeko • Nova is a Fire main DPS who hits very hard in both AoE and single-target fights. What makes her special is the Assist Skill: your teammates spend their own turns calling in the Starblazer to attack, but the damage is still based on Himeko • Nova's stats. If you want a Fire main DPS you can use in all three hard endgame modes, she is well worth pulling.
She suits you best if you already own Trailblaze Companions characters such as Sunday, Dan Heng • Permansor Terrae or Welt, since they can switch on her two Companion Protocol states. She needs at least 1 teammate from this group to turn on a Companion Protocol, so if you have nobody from it yet, think carefully before you pull.
Himeko • Nova is a DPS who scales with CRIT and ATK. Pile on CRIT Rate, CRIT DMG and ATK%, and leave SPD for last.

On Body, CRIT Rate comes before CRIT DMG, and the goal is 100% CRIT Rate in combat. Her Talent already gives her CRIT DMG too. ATK% Boots are better than SPD Boots. On the Sphere, ATK% is a bit better than or equal to Fire DMG Boost. For the Rope, just take ATK%.
CRIT Rate and CRIT DMG matter equally, then ATK%. SPD goes last, because staying at base SPD is the more recommended setup.
Talent comes first: it is what hands out the Assist Skill and gives her All-Type RES PEN and CRIT DMG. Ultimate is next, since it makes up a good part of her damage. Basic ATK goes last, because while she has Navigator's Semaphore she uses the Assist Skill instead of Basic ATKs.
Whither, the Last and First Men? lets Himeko • Nova use her own Assist Skill without consuming Assist Skill uses, and if her uses are full at the start of her turn, she regenerates an extra 5 Energy. Hark! The Express's Pulse Roars gives Trailblaze Companions characters other than Himeko • Nova 1 extra turn to use their Ultimate after they use the Assist Skill. The Silver Rail, Hushed in Antiquity gives her 3 Source Energy right away when she uses her Ultimate.
E1 adds 1 more free Assist Skill per Ultimate rotation and makes it easier to trigger: in Verdict it takes 1 ally Ultimate instead of 2, and in Decimation it takes 6 Charge instead of 9. E2 raises her Assist Skill cap to 2 uses, makes her Ultimate and Assist Skill deal 130% of their original DMG, and also gives the extra turn to characters outside the Trailblaze Companions when they use the Assist Skill. E4 is a modest damage boost and spreads the All-Type RES PEN buff to the whole team, while E6 is the capstone that makes her Ultimate much stronger.
Sunday and Dan Heng • Permansor Terrae can both switch on Companion Protocol: Verdict. Sunday advances Himeko • Nova's action and restores her Energy with his Ultimate, while Dan Heng • Permansor Terrae keeps the team safe and buffs her ATK. In Verdict, every Ultimate from a teammate adds 1 point, and at 2 points Himeko • Nova launches a free Assist Skill on her own.
Right now Welt is the only usable teammate for switching on Companion Protocol: Decimation. Welt and Mortenax Blade both cut enemy DEF heavily and stack Ultimate DMG bonuses on top of each other. Mortenax Blade hits all enemies often, so Decimation's Charge fills up fast, and the constant Assist Skill hits keep triggering Welt's Action Delay and DMG buff.
Himeko • Nova needs Energy and attacks a lot, which makes her a great target for Robin • Summeretto's Ultimate. The catch is that Robin • Summeretto does not take her own actions to use the Assist Skill, while her Ultimate advances Himeko • Nova's action, so you have to plan your turns carefully to use up every Assist Skill use.
Right now he is the only usable teammate for switching on Decimation. His Ultimate lowers enemy DEF and takes some pressure off your sustain, and together with Himeko • Nova's signature Light Cone the DEF ignore easily goes over the cap.
His Ultimate makes enemies take more DMG and lowers their DEF. He hits all enemies often and cycles Energy fast, so triggering the Assist Skill is easy in either state. With another Nihility teammate such as Welt, he also adds 75% to Himeko • Nova's Ultimate DMG.
He switches on Verdict, advances Himeko • Nova's action and restores her Energy. There are two SPD setups: Himeko • Nova at 135 with Sunday 1 point slower (134), or Sunday at 160 or more so Himeko • Nova can stay at base SPD and wear ATK% Boots.
A strong sustain who buffs Himeko • Nova's ATK and switches on Verdict. Her constant attacks regenerate Energy for him, so he uses his Ultimate more often, which in turn gives her more Assist Skills from Verdict.
Gives Himeko • Nova a rare True DMG buff that lasts several turns, and can switch on Verdict. Trailblazer (Remembrance)'s AoE attacks also build Decimation Charge quite well. Time the action advance carefully: Himeko • Nova taking 2 turns in a row while her Assist Skill uses are not used up is a waste.
Cerydra's Military Merit and Skill duplication line up nicely with the Assist Skill, since Himeko • Nova launches it several times per turn. The Energy from the duplicated Skill also helps her get her Ultimate back faster.
A powerful support whose Ultimate fits an Energy-hungry, fast-hitting DPS like Himeko • Nova. In return, you need to plan turns so your team uses up every Assist Skill.
Part of Himeko • Nova's most used team, together with Sunday and Dan Heng • Permansor Terrae. Sparkle also targets her often, which makes Wavestrider Captain a good fit.
While Himeko • Nova is on the field, her Talent deploys the Territory Starblazer Visioscape, brings out the Starblazer and gives every ally character 1 use of the Assist Skill. Whoever uses it, it counts as Himeko • Nova using her Skill, so the damage always runs off her stats. Allies other than Himeko • Nova also regenerate 4 Energy when they use it. In practice, you trade a support's turn for extra damage from your main DPS.
Himeko • Nova's Skill restores all Assist Skill uses and gives her Navigator's Semaphore for 3 turns: all allies deal more DMG, and at the start of every turn she gets back 1 Assist Skill use. That lets her keep using the Assist Skill and almost never press Basic ATK. With the Trace Whither, the Last and First Men?, her own Assist Skill does not consume any uses. Keep in mind that her Skill is locked until Navigator's Semaphore runs out, so you cannot recast it back to back.
When another Trailblaze Companions character uses the Assist Skill, Himeko • Nova enters one of two states. Companion Protocol: Verdict (from the Trailblazer, Sunday or any Dan Heng) greatly increases her DMG, especially her Ultimate, and gains 1 point each time a teammate uses their Ultimate. At 2 points she launches a free Assist Skill. Companion Protocol: Decimation (from Himeko, Welt or any March 7th) increases all allies' CRIT DMG, with extra CRIT DMG on Skills, and gains 1 Charge for every enemy hit by allies. At 9 Charge she launches the Assist Skill on her own. These free attacks can happen up to 2 times, and the count resets each time Himeko • Nova uses her Ultimate. Each state keeps its own points, but picking one state and playing around it is the easiest way to go.
Her Ultimate puts you in direct control of the Starblazer. Hyperluminal Particle Beam hits all enemies and gives 1 point of Source Energy (up to 3), while Orbital Annihilation Pulse spends Source Energy for big damage. The Trace The Silver Rail, Hushed in Antiquity gives her 3 Source Energy as soon as she uses her Ultimate, and if she still has 3 or more when firing Orbital Annihilation Pulse, its DMG multiplier against random single enemies goes up by 30%. Once the Hyperluminal Particle Beam uses run out, the Starblazer fires Orbital Annihilation Pulse on its own and finishes with the Final Hit. If all enemies are already defeated, the Final Hit comes out right away.
Deals Fire DMG equal to 140% of Himeko • Nova’s ATK to one enemy.
After using Skill, immediately recovers all Assist Skill uses. Himeko • Nova gains “Navigator’s Semaphore,” lasting for 3 turn(s).

When the uses of “Hyperluminal Particle Beam” are depleted, automatically launches “Orbital Annihilation Pulse,” followed by Final Hit, dealing 3 instance(s) of DMG, with each instance dealing Fire DMG equal to 100% of Himeko • Nova’s ATK to one random enemy.
When “Hyperluminal Particle Beam” or “Orbital Annihilation Pulse” deals fatal damage to all enemies on the field, or when enemy HP can no longer be reduced, immediately launches Final Hit.
While Himeko • Nova is on the field, immediately deploys the Territory “Starblazer Visioscape,” summoning “Starblazer” to the field and granting all ally characters 1 Assist Skill use. Ally characters can use Assist Skill to call upon “Starblazer” to attack enemies.

During the “Navigator’s Semaphore” state, at the start of each turn , additionally recovers 1 use of Assist Skill immediately. When a non-Trailblaze Companions character uses Assist Skill, the Trace “Hark! The Express’s Pulse Roars” now also grants them 1 extra turn.
