Top Kokushibou x Bottom Muzan cuz yeah, and you can request

Kyojuro Rengoku, the flame hashira, and Tengen Uzui, the flamboyant and speedy sound hashira. Nothing more than good friends at first, an incident aboard the infamous Mugen Train brings these pillars closer for the first time. Like a riptide, once they're caught in the flow, there's no escaping. A certain infatuated uppermoon is determined to cause problems for the two, some attempts more successful than others. And as the two hashira attempt to navigate the increasingly difficult situation they find themselves in, the world only seems to want to keep knocking them back down.
