Mystical Detective

In one of the districts of the city, strange events constantly occur. And who better than a group of school friends to unravel these mysteries?
Who are these mystical creatures: witches, creepy tomato kings, and glowing pinecone-spiders? Why do some children disappear while others turn into monuments? Could it be that spirits stuck between worlds are warning us that we should not commit evil deeds or even think bad thoughts? Or maybe not.
The kids come to the conclusion that Earth is not only a territory for humans but also for mystical beings, with whom one can live peacefully if they are not disturbed unnecessarily.
