Amamiya Yoru accidentally transmigrates to a world where the myriad realms are just beginning to appear. Various monsters and characters from these realms are beginning to emerge. Fortunately, along with her transmigration, Amamiya also obtains a system called "Myriad Realities Role-Playing." By gaining fame through this system, she can draw various characters to role-play!
