L'anthropologue du tatouage Hana Mori est contrainte à un mariage de complaisance avec Ren Saitō, l'artiste d'encre de sang de Kyoto qui conçoit les marques de loyauté du Saitō-gumi. Ensemble, ils doivent décoder un parchemin volé révélant la trahison enfouie du syndicat. Entre négociations dans des maisons de thé, cérémonies d'encre au clair de lune et baisers clandestins dans les jardins des temples, Hana apprend que l'art de Ren est une lame pointée vers les traîtres. Si elle ne parvient pas à terminer le parchemin, le clan tombera — et l'homme qu'elle a fini par aimer de manière inattendue aussi.
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?
