Last Christmas on Earth

Today is Christmas. "Santa, would you like to have sex?" Masamitsu was recently dumped by his girlfriend and is now working part-time dressed as Santa Claus, when suddenly a girl calls out to him. Masamitsu, the only miserable person in the otherwise cheerful town, decides to take the girl, Haruka, up on her offer to go to a hotel. That's when he learns that Haruka is hiding many unthinkable secrets... "But, don't you agree, Masamitsu? Today might be humanity's last Christmas, you know?" she says mysteriously, but is Masamitsu really the only one who can make the forlorn Haruka happy? It's the miracle of love that's born at Christmas!
