NABARU started ninja delivery service.
If you use a ninja to the present to a business partner and a customer? It will become the big impact. If a ninja appears in an event and the party? It will be wonderful surprise. If a ninja appears in the birthday party of kids with a present? It will become the good memory.
NABARU has 3 ninjas now. However, unfortunately this service is only Japan. Support areas are Tokyo, Kanagawa and Chiba. Originally the ninja was a spy and an assassin. However, they do not undertake it by this service and we can't ask them for the works about the crime.
I think that they should go abroad.
You Can Now Rent Ninja in Japan. They’re Not Deadly.
