Synopsis

.There is an energy reaction! There is an energy reaction!"
Glover is collecting main energy from discarded spaceships.
It's a get-rich-quick job in today's energy-starved Earth.
Recently, there are gravity manipulators that make it much easier to operate in space.
What is that? What is that?
Glover happily climbs aboard the abandoned spaceship, but what he sees is a creature that looks like an octopus on Earth.
But it is not an octopus. It had a body length comparable to Glover's and one large eye.
---Pow!
Glover punches out the eye without hesitation.
Sorry...we're risking our lives here, too.
Go on, Glover! Beat the mysterious creature and get rich!
