L'antropologa dei tatuaggi Hana Mori è costretta a un matrimonio di facciata con Ren Saitō, l'artista dell'inchiostro di sangue di Kyoto che disegna i marchi di lealtà della Saitō-gumi. Insieme devono decodificare una pergamena rubata che rivela un tradimento sepolto all'interno del sindacato. Tra trattative nelle case da tè, cerimonie d'inchiostro al chiaro di luna e baci clandestini nei giardini dei templi, Hana scopre che l'arte di Ren è una lama puntata contro i traditori. Se non riuscirà a completare la pergamena, il clan cadrà — e così l'uomo che, inaspettatamente, ha iniziato ad amare.
Step into the hidden, shadowed world of Kyoto’s elite underworld in 'Blood Ink Promise,' where tradition meets betrayal and every drop of ink tells a story of life or death. You are Hana Mori, a brilliant tattoo anthropologist who finds herself caught in the crosshairs of a deadly power struggle. To survive, you are forced into a paper marriage with the enigmatic and dangerous Ren Saitō, the Saitō-gumi’s premier blood-ink artist. Ren isn't just a craftsman; he is a man whose needles serve as a blade against traitors, and his loyalty to the clan is as permanent as the marks he leaves on skin. Your mission is to decode a stolen scroll that reveals a buried history of treason, but as you work alongside Ren, the lines between duty and desire begin to blur. From the quiet tension of traditional tea-house negotiations to clandestine, moonlit kisses in ancient temple gardens, you will navigate a landscape of high angst and dark romance. With our cutting-edge face-swap technology, you don't just read about Hana—you become her. See your own face in every cinematic scene as you navigate the dangerous waters of the Saitō-gumi. Will you be the one to finish the scroll and save the clan, or will the heat of Ren’s touch lead you into a different kind of danger? In a world where ink is bound by blood, can you trust the man who was once your enemy, or will the secrets you uncover tear both of you apart?
