Prika

A Burst 2 Supporter used as a set with Mint.
Just by getting the lineup order right, she locks in Mint's Chorus firepower buff and carries on with Performance healing and charge damage support, providing buffs and survival on par with Mast: Romantic Maid and Anchor.
Fielded alone without Mint she contributes almost nothing, so she is rarely a core pick.

Each time she lands a Full Charge, all allies briefly gain Projectile Explosion Damage, Pierce Damage, and Increased ATK based on the caster's ATK. In the Performance state she keeps healing efficiency and pierce on herself, and using her Burst gives all allies continuous healing based on final max HP plus a Performance with Increased Charge Damage that can't be removed, lasting 25 sec. On entering Full Burst her max HP rises, and after Mint's Chorus is applied, Encore extends Performance duration and further raises allies' attack damage. Because of an increased Burst Cooldown effect, she uses only the first Burst after battle start herself, and Mint handles Burst afterward.

Fire with Full Charge. If you just keep tap-firing in short bursts, the Full Charge buff rarely triggers.
Place her ahead of Mint in the lineup list. With this order, even in auto battle, only Mint uses Burst after the first Burst.
If buff uptime is the goal, keep Auto as the default, and only adjust reload and firing tempo manually when Full Charge intervals slip.

She's a slow-reloading Sniper Rifle, so use the Resilience Cube to shorten Full Charge intervals. Consider the Adjutant Cube for Charge Speed and the Healing Cube for healing support as second options. If the cube level gap is large, use the higher-level Harmony Cube first regardless of ranking.

As a Supporter, her Overload priority is low. Her buffs scale with ATK, so fill ATK lines, and support Full Charge uptime with Charge Speed and Max Ammo.

Skill 1 and Skill 2 handle the Full Charge buff and Performance extension, so raise them first. Fill her Burst after 7 to scale up team buffs and healing.

With Mint, she handles buffs and continuous healing in Solo Raid and boss fights. Fit her into lineups of Burst 3 firepower Nikkes that rely heavily on pierce and projectile explosion.

Paired with Mint, allies get firepower buffs and continuous healing at the same time.
Every Full Charge applies projectile explosion, pierce, and ATK support to all allies.
Performance can't be removed, so Increased Charge Damage and healing last a long time.

Fielded alone without Mint, her buff chain barely works.
She doesn't fit the slots of Burst Cooldown reduction lineups centered on Miranda and Zwei.
Sniper Rifle reloads are long, so if her Full Charge tempo slips, her Skill 1 buff uptime breaks.

Released as a pickup for the Bitter Spice event in 5/2026.
