The title of this chapter is more precisely “Mysterious Saucer U.M.A.”, which is a play on the Japanese title of Gerry Anderson's UFO. There's not really a great way to translate that back since the English title is just the acronym.
There's a new native mentioned, though not named. Suzuki Akira, a special effects technician, specializing in creature miniatures.
I also want to point out that Corona's hair has a similar color and sheen to that of UFO's Moonbase operators.
