The Novel Returns to the First Meeting With Sirius Sugar

The official synopsis opens with the protagonist waking inside the Maze with no memory and immediately being attacked by a giant creature.

He is rescued by Sirius Sugar, a group of Zaltoum Academy students piloting humanoid machines known as MGs. Despite his amnesia, his instinctive tactical ability helps the group make it back to the surface.

That talent eventually earns him a position training Sirius Sugar.

Sirius Sugar Must Defeat Chaos Maiden

Sirius Sugar is far from an elite team. KADOKAWA describes the group as being on the edge of losing its place at the academy.

Their next match becomes decisive: failure to defeat the powerful Chaos Maiden will result in the entire team being expelled.

The novel therefore centers its early conflict on rebuilding an underdog squad while the Commander is still unable to remember his own past.

340 Pages and a Physical-Edition Serial Code

The Japanese release uses a B6 format, runs for 340 pages, and is priced at ¥1,870 including tax.

KADOKAWA also confirms a limited serial code with the physical book. The specific in-game reward attached to that code has not yet been detailed on the main product page.

Arriving After the Game Passed Two Million Players

The novel arrives roughly a year after Muv-Luv Girls Garden initially launched through DMM GAMES in September 2025.

The game expanded to App Store and Google Play in March 2026. EXNOA later announced that the player count had surpassed two million, while the upcoming Steam version currently carries a Q4 2026 release window.

Why This Matters

1) The opening game story receives a full prose adaptation

The Commander, Maze, Sirius Sugar, and the Chaos Maiden match can now be explored through a longer narrative format.

2) The adaptation follows major audience growth

The two-million-player milestone gives the novelization clear context as the franchise expands beyond the game itself.

3) The physical book directly connects back to the game

Its limited serial code makes the release relevant to active players as well as readers.
