Event Details
- Event Name: Invasion! Grandcypher Open House! ~The Captain's A Little Long Day~
- Event Period: March 29, 2026 (Sun) 17:00 – April 6, 2026 (Mon) 18:59 (JST)
Story Synopsis: Who Sent the Invitation?
Some time after the rise of the Crimson Horizon, the crew of the Grandcypher find themselves swamped with a sudden flood of requests. Just then, a mysterious visitor boards the airship, bearing a strange letter.
The letter reads: "Notice: 'Grandcypher Open House' to be Held". The catch? The Captain has absolutely no memory of sending this letter. Who is the mastermind behind this unauthorised event? And so, the curtain rises on the Captain's "a little long day".
Rumour has it that the one behind all this is Echidna, the Primal Beast who governs "motherhood"—and she's even trying to force her way into being the Captain's mom?!

Editor's Special Note
This story has been hailed by some players as "the culmination of 12 years". It features not only heartwarming (?) guardian open house moments, but also may reveal the secret, never-before-seen laboratories of certain characters, including Katana.
