Sumekuni no Souheki: Kizumono no Hanayome Gaiden

They are the Empire's greatest protectors, the "Twin Pillars" of the Onmyoryo. But beneath their heroic facade, Shion and Yuusei share a secret, forbidden love. Bound by an engagement since childhood, their future is shattered when Yuusei’s family rejects him as a "defective."

Forced to watch helplessly as his own younger sister takes his place as Shion's bride-to-be, Yuusei struggles to keep his composure. With the ceremony approaching, will he accept this tragic destiny, or will the weight of their stolen love lead them toward an uncertain end?
