Ambulance

In mythical medieval Japan, 911 is a joke, to quote Chuck D (not something I ever really expected to do). If you're injured you'd better hope somebody's around to lend a hand.

Carrying injured people piggyback is a staple of anime, seen in many series and movies. Piggybacking an adult this way is very hard work, try it some time!
