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?
