Darya

Darya is an exclusive girl available as a DLC bundle that can be purchased for $15. She is the twentieth girl in the game's main tab, but she is not part of the main story and you do not need to unlock any other girls to obtain her. You first meet Darya when you see an ancient rune next to the beachfront which bears an inscription saying that whoever throws diamonds into the water will summon the goddess Darya. The following scene reads "Bank Account - CRUSHED!", but you don't actually lose any diamonds.
