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.)

(As long as I love Blue Archives and all the children here, I will never stop updating. I just sometimes think about the plot to avoid making anyone, including myself, uncomfortable. Hehe, I love every lovely student in Kiwatos so much.) This is a gentle person who came to the utopia of Kiwatos and began their destiny together. Please look forward to the world I have created for Kiwatos, because I love them so much.
