If anyone has any suggestions for more harem members don't be afraid to tell me and I'll see if I can fit them into this world.

They can be deep sea creatures or humans that can be from Port towns, more pirates, more sailors, or something else associated with the sea.

Maybe even throw in a female Cthulhu.

Anyway, see ya'll later for now and enjoy the rest of your day.
