Atsumu Miya and his twin Osamu Miya find themselves in a unknown land. It was like a dream land. It had majestic creatures, and odd people... They both fell onto opposite sides of a gate, it was some kind of border. They had to find each other again, but meet new people doing so..... There will also be other ships but mostly sakuatsu and osasuna Fluff + agnst Maybe smut idk
