Figments

From the introduction:

This is a Role-Playing Game where players take the role of a figment, imaginary beings buried within past memories. The Gamemaster plays the Friend, the creator of the figments during childhood, now an adult with a regular desk job. Responsibilities and the corporate life forced him to “grow up.” Thus, he now has a more jaded view at life. So it’s up to the figments to remind him of the magic and delight life can offer, even at its most mundane moments. Even during something as routine as speedwalking to work because you’re about to be late. Again.
