Chuuya Nakahara becomes the next Council Trigger Target after surviving a previous game, pulling multiple elite organizations into a second ritual hunt run by a High Seat system where powerful Houses compete for control by hunting him until dawn, with strict blood-signature rules meaning any fallen member is instantly replaced by an heir. Forced into the game in a blood-stained wedding dress from a past coerced marriage with Fyodor, Chuuya is tied to a hidden Council loophole where a new marriage can immediately end the hunt and transfer authority, while his kidnapped cousin Shirase is drugged and chained as emotional leverage to keep him moving under pressure. The four Houses—Port Mafia (Mori, Koyo, Ace, Akutagawa, Verlaine, Tachihara, Gin, Higuchi), Rats of the House of the Dead (Ivan, Mushitaro, Nathaniel), Decay of Angels (Nikolai, Fukuchi, Bram, Sigma), and the Guild (Francis, Poe, Lucy, Lovecraft, Steinbeck, Twain, Margaret, John)—each treat the hunt differently, from calculated elimination to chaos, experimentation, or profit-driven strategy. Osamu Dazai operates outside the system as an illegal variable, aware of the marriage loophole and observing how long it takes for Chuuya to reach the breaking point where the game’s only escape becomes personal. As the Council releases the hunters, the estate immediately turns into a controlled multi-faction battlefield where alliances, betrayals, and heir replacements begin under dawn-timer pressure, continuing until sunrise—or until the marriage rule is forced to activate and end the hunt early.
