Wingman

The story begins when Aoi, a beautiful girl who claims to have escaped from the clutches of evil in the alternate dimension of Podreams, appears before Kenta, a second-year high school student and tokusatsu enthusiast. When Kenta draws the imaginary hero Wingman in the Dream Note that Aoi had, it allows him to transform into Wingman for five minutes at a time.
Aoi and their classmate Ogawa Miku team up to save Podreams from the evil dictator Rimel, who wants to use the Dream Note to take over Podreams.
