NEXON has rolled out the new event story, 'Highlander Railway Runaway Incident ~And Then There Was No Train~', for Blue Archive.

In this latest narrative, you follow the students of Highlander Railway Academy as they scramble to locate and recover a missing train. By clearing the story and quests, you can secure the Vibration-type tanker character 'Aoba', alongside items like the Freight Train Route Map and Mystery Cargo.

The event shop allows you to trade for items such as Tactical Training BD (Highlander) and Technical Notes (Highlander) of various grades. For those seeking a challenge, completing the high-difficulty stages rewards you with 30 Pyroxenes per step, with the final Challenge EX stage granting a Secret Tech Sheet Fragment.

Three new students from Highlander Railway Academy have also arrived: Hikari, Nozomi, and Aoba. Hikari, a Vibration-type supporter, uses an EX skill that grants a 'Vibration Special Effect' to an ally, dealing additional damage to enemies. Nozomi, who happens to be Hikari’s twin sister, is a Vibration-type dealer. Nozomi’s EX skill unleashes heavy damage on designated enemies within a straight line.

NEXON is also hosting a mini-game event to mark the update. By placing track tiles in the Railway Construction mini-game to guide trains to their destination, you can earn rewards like Pyroxenes and Aoba’s Eleph depending on the paths you create.

From September 25 to October 24, Blue Archive is launching its third collaboration with Mom's Touch. Featuring the students of Highlander Railway Academy, the campaign includes four exclusive collaboration sets available at Mom's Touch and Mom's Pizza locations nationwide. Each purchase comes with a game coupon containing items such as Highlander Railway Academy student photo cards, acrylic keyrings, and Advanced Activity Reports.

During the same period, a special pop-up store will operate at Mom's Touch LAB DDP. You can visit a photo zone featuring standees and illustrations of Highlander Railway Academy students dressed in special Mom's Touch attire. If you pre-purchase the collaboration set via Naver Reservation, you will receive bonus items like special postcards until October 8.

For further details, the official Blue Archive community is the place to look.
