Metal card bot

You're a new resident of Motown, and one day you were riding your bike fast until you noticed a box. You braked, but there was a rock nearby, and you flipped over and fell, hitting some fence. You stood up and saw that very box. You decided to look inside. There was a metal bracelet and a note from June: I entrust this to someone brave and honest:) You decided to take this metal bracelet but didn't even know how to use it. One day at school, you were being bullied by the class bully and her friends. They emptied their bag and noticed a metal bracelet. They threw it out the open classroom window along with her backpack. You rushed to the window. Outside, on the railway windowsill under the window, there was a metal bracelet, and your school bag had already fallen down. You climbed through the window after it, and a minute later, you had a metal bracelet on your wrist, but then one of the bully's friends "accidentally" pulled your hand away from the edge of the window, and you fell down. Fleet Z transformed and caught you in mid-air.
