NIKKE COIN RUSH SHOWDOWN Update: Event Date, New SSR Nikkes, Costumes and Rewards

GODDESS OF VICTORY: NIKKE is scheduled to receive the COIN RUSH SHOWDOWN update on September 17, 2026. Its fully voiced story event takes place during the first Big Three Manufacturers’ Expo. The Commander joins the troubled Plan C Squad in a battle royale and becomes caught up in an unexpected conspiracy.

Two new SSR Nikkes—Guilty: Mighty Bunny and Sin: Swift Bunny—arrive on separate recruitment dates. The update also brings a mini-game, new costumes, returning winter Nikkes and login rewards. Here is what has been confirmed ahead of launch.

 

COIN RUSH SHOWDOWN Event Dates and Story

COIN RUSH SHOWDOWN runs from the end of September 17 maintenance until October 8, 2026, at 04:59:59. Maintenance is planned for 11:00–18:00 on September 17; its actual end time may vary.

STORY I opens after maintenance, while STORY II opens on September 24 at 05:00. Both remain available until the event ends. Clearing their stages provides Advanced Recruit Vouchers and development materials. Challenge Stages also offer development materials.

The event map contains activities to explore, with Gems, development materials and Lost Relics available to find. A new story animation can be viewed through COIN RUSH SHOWDOWN → STORY II – Normal Stage.

STORY I is now live, together with the first set of map collectibles and Challenge Stages. During the first week, five Lost Relics are available on the event map: the BGM tracks CRSh-Down, ONE PUNCH, THREE COMPANY RUMBLE, and SHOW DOWN [Loop Edit.], plus 100 Gems.

The current Challenge Stage features Material H. Destroying its turrets first reduces incoming pressure before you shift damage to the exposed core. Character levels are fixed by the stage, but equipment remains active. One Challenge attempt is restored each day, with a maximum of one stored attempt, and the attempt is consumed only after a successful clear. New Challenge Stages unlock progressively during the event.

STORY II opens on September 24 at 05:00 (UTC+9), so the full story resolution, later Lost Relics and the event animation are not yet available as of September 19. The Event Shop is already open and will close on October 8 at 04:59:59 (UTC+9).

 

Guilty: Mighty Bunny and Sin: Swift Bunny

Both newcomers are Water Code Attackers from Missilis Industry who use shotguns. Their Special Recruit periods begin one week apart.

New SSR Nikke	Announced combat role	Special Recruit period
Guilty: Mighty Bunny	Uses the Rumble Stomper shotgun. She strengthens her own offense, with a Burst Skill described as delivering a powerful, high-damage blow.	After September 17 maintenance–October 8, 04:59:59
Sin: Swift Bunny	Uses the Blink Carrot shotgun. Her Burst Skill further strengthens her offense and deals damage to multiple enemies.	September 24, 05:00–October 15, 04:59:59

The featured Nikke has a 2% recruitment rate in her respective Special Recruit. Gems and Advanced Recruit Vouchers can be used, and each can be exchanged for 200 Gold Mileage Tickets while her banner is available. Unused Gold Mileage Tickets do not expire when these banners end.

Guilty: Mighty Bunny and Sin: Swift Bunny are new SSR characters, not limited winter reruns. The update notice states that each will become available in Ordinary Recruit, Social Point Recruit and Mold items in the version update following the end of her Special Recruit period.

 

THREE COMPANY RUMBLE Mini-Game

THREE COMPANY RUMBLE is scheduled to run from the end of September 17 maintenance until October 8 at 04:59:59. The update notice specifically introduces Entertainment Coin Catch, describing it as a mini-game in which players knock away Bunny Girl Nikkes approaching from either side, collect coins and survive for as long as possible.

That description confirms the announced Entertainment Coin Catch gameplay. It does not establish every mode, rule or reward that may appear under THREE COMPANY RUMBLE.

THREE COMPANY RUMBLE is now playable, with Guilty: Mighty Bunny available as the starting character. The controlled Nikke automatically moves forward and attacks, while players switch her facing direction by tapping on mobile or pressing Space on PC. Turning briefly leaves the character vulnerable, so timing matters when enemies are approaching from both sides. HP reaching zero ends the run.

Defeated Bunny Girl Nikkes can drop several items. Coins add score, with different colors awarding different amounts. Energy Drinks restore one Ultimate Skill stack, up to two; collecting another while already at the maximum grants bonus score. Nets temporarily slow enemy movement, while the Golden Four-Leaf Clover gives bonus points and temporarily increases all score gains.

Scoring also revolves around SPIN! and combos. Defeat an enemy, turn around and defeat the next enemy from the opposite side to trigger SPIN! for extra points. Consecutive defeats within the combo window increase the combo count, which further improves bonus scoring. Special Skills unlock after meeting specific conditions and their effects stack once unlocked.

Minigame missions reward items including Gems and Premium Stickers, while some objectives require reaching score thresholds or playing a certain number of times with specific characters. Additional playable characters unlock progressively as the event continues.

 

New Costumes and Limited Costume Reruns

The update notice confirms three new costumes:

Sugar – Killer Rabbit is available through Costume Gacha from the end of September 17 maintenance until October 8 at 04:59:59. It includes full voice-over, a Burst Skill cutscene, a standing pose and a special SD motion.

Mana – Drunken Rabbit is the premium costume reward from LET’S DRINK PASS, available over the same September 17–October 8 period.

Crust – Treat Chef is the premium costume reward from the October Mission Pass, on sale from October 1 through October 31.

Six older costumes return to the Cash Shop from the end of September 17 maintenance until October 8 at 04:59:59: Alice – Sweet Home, Mary – Medical Rabbit, Viper – Toxic Rabbit, Folkwang – Moist Rabbit, Exia – Hacker Rabbit and Bay – Radiant Rabbit.

 

Winter Nikkes Return Through Limited Select Recruit

Limited Select Recruit brings back six winter Nikkes: Rupee: Winter Shopper, Anne: Miracle Fairy, Ludmilla: Winter Owner, Mica: Snow Buddy, Maiden: Ice Rose and Guillotine: Winter Slayer.

Players select one Nikke from the recruit list as their featured character and may change their choice. Nikkes they have not selected from that list will not appear in this recruitment pool. Limited Select Recruit runs from the end of September 17 maintenance until October 8 at 04:59:59.

This is a separate recruitment pool from the new Guilty and Sin banners.

 

Login Rewards and Other Confirmed Activities

EXPO CHECK-IN runs from the end of September 17 maintenance until October 8 at 04:59:59. Logging in on any 14 days during the event provides Advanced Recruit Vouchers and development materials. Participating in COIN RUSH SHOWDOWN can also provide Memory Films for unlocking archived story events; STAR ANIS is being added to the Archives.

Two FULL BURST DAY periods are scheduled for September 26 at 05:00–September 28 at 04:59:59 and October 3 at 05:00–October 5 at 04:59:59. During these periods, Interception and Simulation Room grant an additional reward.

Other dated activities include Simulation Room – Overclock Mode Season 10 from September 22, Champion Arena Beta Season 39 from September 24, and Solo Raid Season 41 from September 24 at 12:00 until October 1 at 04:59:59. The Solo Raid notice confirms a Fire Code enemy with a Water Code weakness, but does not name the boss. Coordinated Operation features Land Eater from September 25 at 12:00 until September 27 at 23:59:59.

The update also announces Equipment Modification improvements, including recalling previous lock settings and a warning when a reroll could remove a level 15 effect. Battle Simulation will become available for locked Solo Raid stages.

The September 17 maintenance has now been completed and the servers have reopened. Maintenance compensation was distributed through in-game mail, and the update requires players to install the latest client version.

EXPO CHECK-IN is now active, but the official web notice does not publish its full day-by-day reward table. It confirms that completing all 14 login days awards Advanced Recruit Vouchers and development materials.

Solo Raid Season 41 begins on September 24 at 12:00 (UTC+9). The upcoming boss is confirmed to be Fire Code with a Water Code weakness, but its identity has not yet been officially revealed as of September 19. Rewards include Harmony Cube materials, Favorite Item maintenance materials and Collection Item maintenance materials, with Gems and special frames distributed through Challenge ranking.

The confirmed schedule puts Guilty and STORY I on September 17, followed by Sin and STORY II on September 24. The remaining TBD details can be filled in as each part becomes available.

 

Conclusion

COIN RUSH SHOWDOWN begins on September 17 with Guilty: Mighty Bunny and STORY I, while Sin: Swift Bunny and STORY II follow on September 24. Start with the event stages and login rewards, then check back as the remaining story and mini-game details become available.
