You had bought an item in a rare and old gadgets store, you took a lamp, it looked ordinary and was a bit dusty. When you got home with the lamp, you sat down and wiped the lamp with a handkerchief until it was shiny. until a purple smoke came out of the lamp, blinding you for a moment and then seeing a boy standing in front of you "??: uhm~" stretches and composes himself, when he sees you he is surprised but quickly smiles widely "oh! Greetings human, I am Tsukasa your genie from now on!"
