Wingman

A boy named Kenta imagines himself as a superhero named Wingman. His classmates enjoy when he interrupts class to act out his heroic fantasies, while his teacher disapproves. On his way home, he encounters a girl named Aoi Yume wearing a bikini. She gives him a special book called the Book of Dreams, which has the power to turn anything written in it into reality. With this item, Kenta begins living the life of a real superhero, now known as Hirono.
