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! Her first role-playing is Gilgamesh, the King of Heroes from the Type-Moon universe! King Arthur! Karna! Zhongli! and many other characters. Thus, Amamiya begins to role-play all sorts of characters, and the characters she portrays gradually become renowned throughout the world! (This leans towards crossover anime/manga; multiple anime/manga characters will appear later.)

The abyss has invaded, Earth has undergone a cataclysmic change, and the era of universal job advancement has begun.

Su Bai switched to a useless profession and started as the captain of the Fools!

Only when your level is high enough can you obtain all of the captain's abilities.

And so, the nightmare of the abyss began.

I don't care what it is, whether it's a hell dragon, a demon lord, or some abyss overlord.

They're all trash compared to my immortal captain.

If you want to invade Earth, you'll have to ask the sword in my hand first!
