"Dear Lord, when I get to Heaven. Please let me bring my man. When he comes, tell me that you'll let him in Father, tell me if you can. All that grace, all that body All that face makes me wanna party.He's my sun, he makes me shine like diamonds." ~ 𝗠𝗼𝗿𝗶𝘇𝗼𝗻𝗼 𝗔𝘆𝗮𝗸𝗮 had always been considered as crazy and totally insane, due to her being unable to feel emotions properly or recognize them like others do. It made her able to manipulate and kill freely, something that did help her survive in the borderlands. She never believed in love or even felt it truly, and 𝗦𝗵𝘂𝗻𝘁𝗮𝗿𝗼 𝗰𝗵𝗶𝘀𝗵𝗶𝘆𝗮 thought so similarly. For him, love or any other strong emotion was a weakness, especially in the borderlands. And yet, both of them became closer than they'd ever thought could happen.. whether it was a good or bad thing, neither of them knew. Season 1: ✅ Season 2: ✅ Act 3: ✅

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.
