Cosmea (コスメア) is a character who has yet to formally appear in anything. She is an angel.


Cosmea is a four-winged angel with raceless white skin and pink eyes with white pupils. Her hair seems to be layered and it is tied into two low twintails, having white ribbons as accessories. She wears a light blue-green maid outfit and brown laced boots. In addition to this, three white Cosmea flowers are seen hanging on both sides of her side fringe. She also has a visible halo floating on top of her head. 


Not much is known about her. She seems to love Daimonji.


Not much is known about her.


Up to this day, Cosmea has only appeared in some of Deep-Sea Prisoner's illustrations.



Daimonji seems to be Cosmea's lover.


Higan is Cosmea's daughter.


  • Cosmea's name is derived from a flower, specifically from the Cosmos bipinnatus species.[1]
    • A Cosmea flower is from the Cosmos family. (wherein in the language of flowers, it means "peaceful" or "joy in love and life")
  • Much of Cosmea's background has been speculated by fans, using official information presented in the form of translations of Deep-Sea Prisoner's comments and Deep-Sea Prisoner's artworks and comics.
    • Deep-Sea Prisoner has stated before that Daimonji "lost" his lover. Several artworks focused on romantic themes show Daimonji and Cosmea together as lovers, and they have a daughter named Higan. This has led to many speculating that Cosmea is deceased, although this hasn't been proven.
    • Due to Cosmea being an angel, and likely under the subordination of a God, it has been speculated that she's an underling to the God Fumus; God of the Pitch Black World, based upon her lover's affiliation with the Pitch Black World, Daimonji having been a former subordinate to the wife of the aforementioned world's Devil.
