What happens when a doctor, cold as an operating table, meets the girl who matches his brain and fills the hole in his heart while he's trying to use her for a plan? Shuntaro Chishiya doesn't do "feelings." In the twisted reality of the Borderlands, emotions are a liability-a glitch in the system. People are just tools, and Chishiya is the master craftsman. When he first sees Akai, he sees the perfect weapon: a lethal agent with a mind as sharp as his own and a survival instinct that rivals his clinical detachment. His plan was simple: use her skills to collect the cards and discard her when the game was won. But Akai isn't just another player. She is a storm he didn't forecast. As they navigate the blood-soaked arenas of Tokyo-from the psychological traps of the "Beach" to the final, haunting games of the Face Cards-the hunter becomes the protector. Between the adrenaline of near-death escapes and the quiet, heavy tension of the nights in between, Chishiya finds his cold logic failing him. For the first time, he isn't playing to win the game; he's playing to keep her alive. In a world designed to strip you of your humanity, they found something worth surviving for. This is the story of how a man who saw life as a game of Diamonds realized that a single Heart was the only card that truly mattered.
