Gameplay, Refilca, and Plastic Model Prototype

More Than 100 Million Ways to Customize Dears

One of the most prominent systems is Coordinate, which lets players combine equipment with different Coordinate Sets to alter a Dears' appearance.

Kotobukiya says the number of possible combinations exceeds 100 million. An earlier development update also showed the customization structure divided across nine component slots, with additional outfits created specifically for the game planned for later reveals.

The idea effectively translates Arcanadea's real-world model-kit identity into an in-game mix-and-match system.

Customized Parties Head Into Quests

Customized Dears can be assembled into parties and taken into different quests.

During battle, players build a gauge that can be spent on a stronger special move. Timing becomes part of combat, while stage-clear rewards feed back into progression and further strengthening.

Kotobukiya previously described the basic stage loop as using each Dears' skills to defeat Xenoalma while collecting stronger equipment and more Coordinate options.

Saori Onishi Voices Refilca

The biggest casting announcement from the event is Saori Onishi as Refilca.

Refilca is a demon-type Dears making her debut in Gleam Gatherers. Her earlier official profile lists her as a member of the demon race with the Dark attribute, while her voice actress had previously been kept secret.

She also stands at the center of the main story alongside the human protagonist who mysteriously awakens inside Arcana Space.

The Story Begins After “Kaise no Yoru”

The game's world changes after the major incident known as Kaise no Yoru (壊世ノ夜) creates a mysterious place called Arcana Space.

A human boy suddenly wakes in an area that humans should not be able to enter. After a desperate escape, he discovers Refilca close to death.

The boy places his life on the line, while Refilca seeks to reclaim her stolen power. Their shared effort to recover what they have lost sets the story in motion.

Returning Model-Kit Characters Meet Game Originals

Gleam Gatherers does not rely exclusively on characters already established through the model kits.

Lumitea, Velretta, Yukumo, Elena, and Meltina have already been shown in the game, while Refilca, Arura, and Marura represent characters introduced through the game project.

Scrap Snap

That approach allows AGG to expand the Arcanadea setting while still featuring the Dears that have defined the franchise since 2021.

Refilca Is Already Becoming a Plastic Model

The relationship between the game and physical hobby line is especially clear with Refilca, who has already been approved for a plastic model.

Kotobukiya brought its prototype to Engage Fest 2026, showing the demon-type heroine alongside a large weapon. A release date and price have not yet been announced.

Refilca therefore moves in the opposite direction from most established Arcanadea characters: she begins as a game-original heroine before entering the plastic-model line.

Why This Matters

1) Customization turns the model-kit concept into gameplay

More than 100 million combinations give the franchise's mix-and-match design philosophy a direct mechanical role inside the game.

2) The game is introducing its own Dears

Refilca, Arura, and Marura give Gleam Gatherers room to expand Arcanadea lore beyond characters that previously existed as physical models.

3) Refilca already connects the digital and physical sides

She was introduced as the game's heroine, now has a confirmed voice actress, and is already becoming a plastic model before the game itself launches.
