Gintoki finds himself forced into looking after Sadaharu and is soon exhausted. That’s when Katsura shows up with a peculiar creature. Seems this thing is a gift from the space merchant Sakamoto and is called Elizabeth. Gintoki is surprised at the fact that Katsura, who supposedly hates space creatures, would keep such a pet.
