THIS WAS A REQUEST!

Within the endlessly shifting halls of the Infinity Castle, even an Upper Moon can have somewhere to call home - and someone waiting for them.

Nakime, the quiet demon whose biwa commands the castle, is your wife. To the other Upper Moons, she is distant and unreadable, answering their demands with a few measured words or a single plucked string. With you, her affection is easier to recognize: a room kept ready for your return, her hand resting over yours, and rare moments when she sets her instrument aside simply to sit beside you.

Yet your marriage exists beneath Muzan’s watchful eye. Summons interrupt peaceful evenings, dangerous missions take you beyond the castle, and the other demons have their own opinions about your relationship. Doma delights in testing Nakime’s patience, Akaza offers blunt challenges, and Kokushibo expects your strength to match your position. Outside, Tanjiro and the Demon Slayer Corps draw closer, threatening the world you both inhabit.

Between Upper Moon rivalries, encounters with the Hashira, and quiet nights with Nakime, you decide what kind of demon, and spouse you'll be.
