Rocma is a scary polar bear and comes off as cold and rough. She tends to warn the residents about going near the Orca Danger Zone. She hates depending on men since it means defeat for her. She's very scary if someone makes her angry. Despite her cold personality, she genuinely loves Mafuyu, and cares about all her friends.


Not much is known about her.

Ice Scream Cast


Idate is one of Rocma's enemies. She is the only resident of Iceberg Isle who dares to counter him. He has an unhealthy obsession with her. In return, Rocma finds Idate a repulsive man.


Rocma acts as Mafuyu's parental guardian, and 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 Mafuyu and her siblings, they are on relatively friendly terms.


Rock is Rocma's neighbour, 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.
