There are three genders in a parallel world, namely Omega Alpha Bite. That world does not accept homosexuality. However, as the incarnation of the ocean, it is not allowed to fall in love with humans. But the funny thing is that the incarnation of the ocean fell in love with an ordinary girl in the human world. When the girl died, the incarnation of the ocean ridiculously gave her pearl to the human girl in an attempt to revive her.
Concept: What is the end of the ocean?
