In the rigid hierarchy of the Empire’s aristocracy, the free-spirited duchess Scarlet refused to conform, and was framed for Regicide, the assassination of the Emperor.
With the help of Lily, the captain of the cutting-edge Stream Airship, Scarlet escapes the imperial capital and declares war against the Empire!
As Scarlet’s recklessness and Lily’s cold pragmatism collide, the conflict soon engulfs the entire continent.
Capture enemy generals, turn them into allies, and clear Scarlet’s name as you fight for the duo’s happy ending!
Victory is achieved by "capturing" or "executing" enemy generals.
Defeat comes if either Scarlet or Lily falls in battle.
Secure only the essential supply line outposts, and carve a path of invasion using your limited forces and the Stream Airship.
You can ambush, prolong sieges or a full-scale attack... Nothing is off the table.
Units stationed at outposts connected to your headquarters via “lines” receive powerful support every turn. This applies to both allies and enemies.
Get cut off, and you’re in danger. Cut the enemy’s line, and an opportunity arises.
What matters isn’t territory, but maintaining critical supply lines.
Do not get distracted by the enemy!
The enemy comes in overwhelming numbers, backed by sudden reinforcements and surprise attacks.
Scarlet’s army is too small to defend every front.
Abandon unnecessary outposts, do NOT hesitate, and focus your forces on a single enemy general.
Build a supply line that maximizes your power and give it all to the enemy general!
The Stream Airship is your ultimate battlefield tool, exclusive to your army.
Freeze enemy advances with <Stalling Stream>, cut off their supply line to the frontlines with the <Interception Stream>.
Convince entire squads to surrender or defect with the <Surrender Stream>, and even boost movement to intercept ambushes with the <Hustle Stream>.
There are countless strategic uses.
But the most important is the <Capture Stream>. While it’s active, you can capture enemy generals!
Activating the Capture Stream lets Lily use her skill to take enemy generals alive.
Captured generals will join your side, bringing unique abilities and new stream options.
Capturing all enemy generals is the only path to Scarlet and Lily’s true happy ending.
(Even if they don’t join right away, as long as they’re captured, you’re safe!)
You can execute generals instead of capturing them, and the story will still progress.
This pushes Scarlet and Lily closer to becoming Demon Queens, greatly increasing their combat power...
But the truth will be lost forever.
Capture them all, or kill them all and seize the power—the choice is yours.
Allies grow stronger as they fight, and fielding certain pairs together and winning a fight increases their trust level.
When trust levels reach a certain threshold, Unite Episodes will occur, and deepening the trust further will unlock powerful tag-team bond skills named Unison Skills!
