These Siblings Are Brutal at the End of the World

With just twenty-four hours left on the countdown to Earth's destruction, a brother and sister with astonishing backgrounds are about to awaken. Advanced civilizations from across the universe have joined the competition. Are the two of them humanity's saviors, or the aliens' accomplices? What massive conspiracy lies behind the plan to destroy Earth?

"Sis, don't stick too close to me. I'll never find a girlfriend that way."

"So you really are a rotten brother who cares more about girls than his sister!"

"If I don't hurry up and marry an Earth girl, I'll have to go back to my home planet and inherit the throne."

"Well, that makes sense!"
