Hello, sir! Am I correct to assume that you are from the surface? Outside of the Kojin, we do not receive too many visitors. Then again, it is only to be expected. We live at the bottom of the sea, after all!
Long ago, in exchange for the treasures we gave them, the Kojin taught our ancestors the secret to living in this great expanse of water.
We have resided here since, as their neighbors. They are a very kind-hearted and clever people, who love collecting rare items. It would greatly benefit you to befriend them.
Aha! One moment─something is coming to me. Yes! I know. If you were to wipe out some of the awahaki growing around their village they are sure to be extremely pleased! About six should get you in their good graces.
