Beautiful Dreamer follows Ataru Moroboshi, a lecherous if properly-meaning substantial schooler and his extraterrestrial fiancée Lum as he and his friends scramble to finish preparing for their higher school’s once-a-year faculty festival. When a compact military of extraterrestrial land builders move into town to destroy the small-cash flow housing in and all-around the metropolis, the brothers attempt to protect their turf and fight again.
