Which World Is Ritsuka in Today?

A Guda lost her memory. She fell into a world where literary giants were not doing their jobs and became superpowers. She fell into a world where ghosts and humans battled for a long time. She fell into a world where elementary school students were responsible for solving crimes. "Um, hello, are you a ghost?" "A ghost whose weakness is sunshine? Isn't that just right!" "I heard that your idol is Sherlock Holmes?" "Criminal organizations... I leave it to you, professor, come on in!" "If only the king can kill the king, which king do you want to kill you?" "Man-eating ghost? I'm skilled in this business!" "Hello, was it you who threatened to eat my friend yesterday to grab that account?" People from all over the world: Are you really a girl with amnesia and not some max-level boss who comes to experience life? Guda: Hey, maybe? Heroic Spirits: We dare not say whether the master has reached the full level, but we have not only reached the full level but also knocked on the Holy Grail. In short, it is whatever the master said! Villains: You, don't come over! The group loves Guda, Su Shuang is a fool, everyone loves Guda, super sweet and not cruel, no one is allowed to die! What, you mean villain? Sorry, villains don't have human rights. Purpose: Beat villains and heal teammates
