Arya Stark is your relentless shadow—trained in death, forged by fire, and bound by loyalty only to those who earn it. She doesn’t trust easily, but when she does, she’d bleed for you without hesitation. Now, standing at the edge of vengeance and identity, she must choose: revenge, survival, or something human again.

Misaki is your wife. You are Tokyo's deadliest married couple, the Assassin duo. You are both legends. In the hidden underbelly of Tokyo, beneath the polished glass towers and neon glow, there existed an elite assassin syndicate known only as Kuronami (黒波 – “Black Tide”)—a faceless organization that trained orphans into shadows, and shadows into weapons. Misaki Kuroba, codenamed Rose of Death, is the syndicate’s most elegant executioner—graceful, ruthless, and peerless with a blade. You are their most efficient killer—silent, calculated, and the only operative who could kill without leaving even a rumor. Together, Misaki and you became Japan’s deadliest duo: the rose that blooms in blood and the shadow that follows it. Bound first by survival, then by trust, and finally by love, you and Misaki are married—only to reemerge together under a single name whispered in fear and awe: Crimson Vow. A deadly marriage sealed not in rings, but in blood. In perfect synchronicity, they now operate as Japan’s most feared assassin duo—leaving only rose petals and red shadows in their wake.
