Blue Archive 9/29 Update: Swimsuit Banners & Events

Blue Archive 9/29 Update: Swimsuit Banners, Returning Event, and More

Blue Archive's next major update arrives on 2025-09-29 (Tue), bringing a fresh wave of Swimsuit Pick-Up Recruitments, a returning event story, and new endgame challenges. For Senseis, this update is a critical pivot point: the 9/15 Dress banners end the same day, and several time-limited shops and events are closing. Whether you're hunting for Swimsuit Nagusa or preparing for the Grand Assault, here's everything you need to know to plan your Pyroxene and stamina efficiently.

This update also introduces a new furniture item and interactions, plus a content shop refresh. For more Blue Archive news and guides, check out our game hub.

Banner Breakdown: Swimsuit Nagusa and Returning Favorites

The first banner phase is headlined by Nagusa (3★, Swimsuit), a new limited student. She is joined by returning Swimsuit units Kikyou (3★), Renge (2★), and Yukari (3★). All four share the same recruitment period, ending on 2025-10-06 01:59 UTC. Note that Recruitment Points reset when this phase ends, so any unused points convert to Keystone Pieces at a 1:1 ratio.

Should You Pull?

• Nagusa (Swimsuit): As a new limited unit, her long-term value depends on her kit, which is not detailed in official materials. If you're a collector or meta-chaser, she's a priority. Otherwise, wait for community testing.
• Kikyou (Swimsuit): A strong rerun for those who missed her. She fills specific roles in certain raids.
• Yukari (Swimsuit): Another limited rerun; useful in PvP and some PvE content.
• Renge (Swimsuit): A 2★ unit, often easier to obtain. Pull if you need her for specific team compositions.

For F2P players, the safe play is to set a budget and stick to it. With the second phase featuring Kazusa (Band), Yoshimi (Band), and Natsu (Band) starting 2025-10-06, you may want to split your Pyroxene. If you're aiming for multiple units, prioritize based on your roster gaps. For a deeper analysis, see our 9/29 banner guide.

A new furniture item, Glacier-Cold Refrigerator, can be obtained from the event, and Nagusa (Swimsuit) has a special interaction with it.

Pre-Patch To-Dos

Before maintenance begins on 2025-09-29 02:00 UTC, make sure you:

• Finish any ongoing 9/15 Dress banner pulls and claim Recruitment Points before they reset.
• Clear out event shops from the previous event, as they may expire.
• Use up any expiring stamina or tickets.
• Claim compensation from the mailbox after maintenance (valid 7 days).

For a detailed checklist, see our 9/29 maintenance guide.

Day-1 Priorities

After maintenance, focus on:

1. Claim Pyroxene x360 from your mailbox.
2. Start the returning event to begin farming currency and clearing the shop.
3. Pull on banners if you're targeting Swimsuit Nagusa or reruns.
4. Attempt Joint Firing Drill for coins and credits.
5. Check the refreshed shops on 2025-09-30 for new items.
