Ninjassassins are not just ninjas who are assassins.
We are also fish farmers.
This is because we must keep the world in good supply of smelly tuna fish, especially since one of our members tends to slap everybody with fish, even herself.
We also need to breed fish for sashimi and sushi.
Note that we only breed the best, and our tuna fish happen to be the precious bluefin tuna!
