An Electric Code, Burst 3 Attacker Submachine Gun Nikke whose weapon changes on Burst for big burst damage, but Tilting Scale is wiped every time Full Burst ends and must be rebuilt.
In fast Burst rotation lineups, it is hard to build many stacks, and without Crit Rate and accuracy support, she struggles to reach her designed damage.
She is worth using when elements line up, such as Raids and boss fights against Wind Code enemies (Electric advantage), but she is hard to call an essential DPS covering Story and Tower broadly.

Each Last Bullet attack stacks Tilting Scale on herself, raising Crit Rate, and when multiple pellets land a critical hit, extra damage is added. When Full Burst Time ends, all Tilting Scale stacks disappear.

While Tilting Scale is active, all allies get Realization of Justice, reducing Max Ammo and increasing Attack Damage. When Full Burst ends, Realization of Justice is also cleared.

Her Burst Means of RighteousnessB changes her weapon, altering pellet count and damage type and greatly lowering attack speed, while granting herself Increased ATK based on caster's ATK and Attack Damage increase.

Align shots and reload order so Last Bullet attacks go off.
Building many Tilting Scale stacks requires delaying Burst timing, which often clashes with the squad's overall Burst rotation.
In boss fights you can run her on auto, but for burst damage it is better to manually manage aim range and reload windows.

Her reload time is long, so easing reload speed comes first. If Submachine Gun pellets miss, the extra damage condition breaks down, so a Hit Rate Harmony Cube is the runner-up. Burst Gauge filling speed is an option for fast-rotation squads.

Crit multiplier, Elemental Advantage, and ATK are the baseline. Missed pellets reduce procs, so some Hit Rate options are also added.

S1 weighs heavily on Tilting Scale and extra damage, while S2 keeps Realization of Justice values up for long. Her Burst raises both buffs and damage coefficients during the weapon-change window.

She contributes strong damage in boss fights against Wind Code enemies (Electric advantage) and Electric Solo Raids. In Story and Tower mob fights she drops in priority due to range and Burst tempo.

During Burst, ATK and Attack Damage buffs stack with weapon-change damage to create burst damage.
While Tilting Scale is active, she raises allies' Attack Damage but lowers their Max Ammo.

Tilting Scale disappears every time Full Burst ends, so stacks must be rebuilt from scratch, and her reload is slow for a Submachine Gun, limiting Last Bullet frequency.
Even when her weapon changes, her base weapon type remains Submachine Gun, so Shotgun-only buffs do not fit.
