BRIGANDINE ABYSS Story Mode follows a single narrative thread that switches between six playable factions: Gran Dragnica, Scarlet Will, Mystiaine, Alicebell, Pandemyuon and Samura Clan. Each faction gets its own leader, knight roster, monster affinity and starting position on the Meltitea map, and the campaign rotates the player through three-character perspectives per run. Campaign length is summarized as a research-date status from official store copy.
Meltitea continent and the Abyssloa premise
Story Mode is set on the continent of Meltitea two centuries after the Abyssloa Empire's fall. Six rival nations now fight over the legacy armor called the Brigandine, with each faction pursuing its own agenda for continental dominance. The premise is fully explained on the Happinet official site and the Steam store page for newcomers who want the setting before picking a faction. The Lunadea mythology drives the magical Brigandine system that lets select generals summon monsters and command knights in turn-based hex grid battles. Each faction's leader carries a Brigandine artifact that unlocks Rally actions and monster summons during the Attack Phase.
The six Story Mode factions
Story Mode rotates the player through three-character perspectives per run. Each of the six Story Mode factions — Gran Dragnica, Scarlet Will, Mystiaine, Alicebell, Pandemyuon and Samura Clan — has its own leader, knight roster, monster affinity and starting position. The factions-overview page lists each faction's flavor and recommended playstyle; the characters-overview page lists the named knights and generals per faction.
Campaign length and three-character rule
Story Mode campaign length is summarized only as a research-date status from official store copy. The three-character rule means each run follows three specific characters through the campaign arc; switching factions swaps the perspective rotation. This structure encourages replayability: completing one faction unlocks the perspective of the opposing factions, which keeps the narrative thread visible from multiple angles. Voice talent is announced by Happinet and NIS America on a per-region basis; the launch-day language list is English, Japanese, French, German, Simplified Chinese and Traditional Chinese with the original Japanese voice track plus English recording.
