Rocma (ロクマ) is a humanoid polar bear from Deep Sea Prisoner's series, Ice Scream. She lives with Mafuyu and has a deep dislike for Idate.


Rocma has white skin, hair, and black eyes with white pupils. Her hair is tied into braids held with pompoms, and she wears a fluffy, white hat with a gray ribbon over her notched left ear. She wears a fuzzy, white scarf, a gray, double-breasted coat-like dress with fur at the hem and cuffs, and gray and white boots with white ribbons accented with pompoms.


Rocma is a scary polar bear and comes off as cold and rough; angering her will reveal her more ferocious and terrifying side. She's also rather stubborn. In spite of her demeanor, however, she has a decent personality. This is further proven when she is seen watching over the residents as well as being a gentle and caring parental figure to Mafuyu.

Rocma's interactions with the male characters present on the isle show that she has a less favorable view of them, often finding them irritable; she has stated before that she considers depending on a man "death" for her. She also doesn't consider cowardly and meek men, such as Shirogane, to be men. On that note, Rocma has also confessed to Shirogane and Yukisada that looking at the two evokes murderous intent within her wanting to rip them to shreds.


Not much is known about her past. At some point, she took Mafuyu into her home.

Ice Scream Cast


Idate Rocma's enemy. She hates him to death and is the only resident of Iceberg Isle who dares to counter him. He, in turn, has an unhealthy obsession with her.


Rocma acts as Mafuyu's parental guardian, and she is also her housemate. 


Shirogane is Rocma's neighbour. Rocma has stated how she wishes to rip him to shreds whenever she looks at him. She views him as "beyond boneheaded" for using a boat during times when orca attacks are frequent. When Shirogane saves her from drowning, she vehemently shows her dismay to being saved by him due to his gender, but thanks him after blandishment from Peraco.


Peraco is Rocma's friend and neighbor. Though Rocma continuously denies Peraco's invitations to playdates with her siblings and Mafuyu, they are on relatively friendly terms.


Rock is Rocma's neighbor, though they have yet to be seen interacting; however, they share the same distaste in Idate.


Yukisada is Rocma's neighbor. Rocma has stated how she wishes to rip him and Shirogane to shreds whenever she looks at them.


  • Rocma seems very strong, almost equal to Idate in battle, though the later has an advantage in water.
  • The origin of her name is from the Japanese word "シロクマ" ("shirokuma" meaning "polar bear").
  • Rocma has a wooden board pinned on a wall in her house which she uses to either to sharpen her claws or practice her claw based attacks.
    • It has been stated that sharpening her claws is a hobby of hers.
    • This could be inspired by the behavior of bears where they scratch trees to mark them or to communicate with other bears.
  • Rocma apparently really enjoys mikans; she will order a whole boxful to Iceberg Isle. She thinks she is being secretive about it, but others already know.
