(The combat power of all worlds has been balanced. Apologies for the ooc character design. The last Xu Fu kiss is adorable.)

Su Yin traveled through the Type-Moon world and thought he would become an ordinary person and live his life in fear, but unexpectedly he was bound to a knowledge system.

At the beginning, he gained the ability of [Knowledge Deconstruction] and was pulled into the chat group of all worlds, and from then on began his journey of continuous adventure across the world.

"Knowledge is the cornerstone of modern magic. With enough knowledge, any magic trick, even sorcery, can be deconstructed!"

——Su Yin

Traveling through the world of martial arts, Su Yu obtained the role of Gilgamesh, nicknamed "Golden Flash," the Hero King of the Type-Moon world. He established a mythical land, the master of the Golden City, and summoned heroes like Artoria and Joan of Arc to serve him. Just as Su Yu was about to establish an immortal dynasty, the Golden List of the Great Dao was revealed! A list of heroes from around the world was compiled, revealing the many heroes of the Golden City, and Su Yu was at the top! Shocking the world! It turns out that there really is an ancient king in this world, two-thirds divine and one-third human! His royal treasury contains the most ancient treasures in human history.

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.)
