Темная ложь

Many centuries ago, twelve immortal warriors of the divine guard, having stolen and opened Pandora's box, unleashed the ancient evil imprisoned within it. As punishment for this, they are compelled to bear demons within themselves. Gideon, an immortal warrior possessed by the demon of Lies, experiences great suffering every time he speaks the truth, yet he is able to unfailingly distinguish truth from deception.
One day, his fellow warriors bring a prisoner named Scarlet to the fortress, also possessed by a demon, and she claims to be Gideon's wife. The beauty indeed seems vaguely familiar to him, but his memory has retained neither how he married her nor any intimacy with her. However, Gideon desperately wants to remember everything. As strongly as he desires her. For a future with her, he is willing to risk everything. Yet the truth turns into a real threat to his love.
