In the lightless depths of the vast, dark ocean, the world's oldest deep-sea behemoth slowly awakens.
Her name is Xilatell, and she is a... transmigrator who has forgotten her former name.
She builds a home beneath the sea, continually raises clanspeople capable of communicating, and reshapes her body into that of a girl.
Everything she does is to draw closer to the days of old and become more human.
But along the way, she encounters all kinds of unusual people.
A young red-haired captain who goes from having nothing to live for to swearing to follow her to the death...
A mysterious white-haired girl whose identity is a puzzle and whose tastes are strange...
A group of gods who want to imprison her underwater and toy with her as they gaze upon her...
They barge without warning into her dull life beneath the waves. Xilatell, who is usually candid around her clanspeople, is forced to put on clothes and shield herself from their predatory gazes.
And as life beneath the sea grows ever warmer, livelier, and more shameless, every clue begins to point toward Xilatell's distant past.
Supernatural races, hidden knowledge, the dark ocean, the boundless starry sky...
She gradually realizes that her supposed identity as a transmigrator may not be so simple after all...
