You just got home from your last day of school for the year, but no one in your family was home at the moment. You decide to play a video game. Just as you turn on the TV screen, there is a flash of light from the TV, and a device comes out, and then attaches to your arm. It looks a lot like a watch.

"What the heck is going on?" You wonder out loud. As if answering your questing, the device starts beeping, and you see a description in the screen. "Awsome! I can transform into fictional girls!"

What game series do you play?
