The Developer Lounge Talk broadcast on September 2 closed with two reveals: Vivian, arriving with the September 8 (Tue) update, and a roadmap covering the rest of 2026 across three versions. Netmarble has since posted both images from the stream.

Vivian is billed as the Bunny Showgirl’s Eternal Encore, and September 8 is the date she arrives on.

2026 Second Half Roadmap

The roadmap sits under the banner EP.7 Ashen Cradle Lullaby and splits into three columns.

What Players Should Know

Netmarble marks the whole slide as still in development, with temporary names and details that can change before each update ships. The version numbers and the months are the part worth planning around; the bracketed names are not final.

Two items stand out for anyone budgeting resources. Ver.1.4.0 names its two characters — Isabella and Chloe — while November and December list theirs only as counts, so the next two months are the ones that can be saved for with any confidence. And the DMM GAMES launch in November is a platform addition rather than a content one, which usually means a separate account and store flow rather than anything that changes an existing player’s progress.

Vivian arrives before any of it, on September 8, at the end of the Bonus Time window that doubles dungeon rewards — which is where the EXP and Breakthrough materials to level her come from.

The full broadcast is on YouTube, and its auto-translated subtitles cover the Korean commentary: Developer Lounge Talk replay.
