Frollo the Legendary Resonator

In a modern city, Li, who transferred to school because of his parents' business, met a girl with gray-green hair who was practicing violin in the community. It was because of this chance encounter that Frollo and Li unknowingly entered a field that had been deliberately hidden from the world for thousands of years. "Child, I see your bones are amazing. Do you want to be a sympathetic speaker? Food and housing will be included!" PS: I want to create a world where Frollo is happy! Resetting the world view, the game plot should not appear until the middle and late stages. It can be regarded as a parallel and resonant modern world, and some original characters may join the plot in more... Bizarre ways.
