Two crimson moons, and darkness falls. Civilization crumbles, and the world sinks into ruin.
As the "Dark Mist" devours the Shattered Light Realm, humanity's last sparks huddle inside enormous "Dome" fortresses, struggling to survive. In its death throes, the world's consciousness gives rise to its final means of fighting the darkness: armor summoners, who wield energy through their bodies, and card makers, who weave miracles with their minds.
Li Hao, a soul from another world, opens her eyes in this desperate hell. Weak, socially anxious, and timid, all she wants is to hide. Yet the world gives her the very talent that demands she work with others: the gift of a [Card Maker]. Armed with strange knowledge from Blue Star, she creates cards with astonishing effects, making her the target of every faction.
Yan Yan is a cold armor summoner, the sharpest blade in the darkness and the Dome's strongest shield. During a mission, he shields a trembling girl from a monster's claws, unexpectedly forging a mysterious [Soulbond Pact] with her.
Forced into the spotlight, the socially anxious girl paints hope for the entire world with trembling hands. The proud, solitary man learns to listen and communicate, using his undying flames to clear the shadows from her path.
As the darkness surges once more and an ancient conspiracy comes to light, the truth of the apocalypse gradually emerges... They discover that true power comes not from armor or cards, but from the heart
