Rocma often comes off as cold and rough; angering him will reveal her more ferocious and terrifying side. He is rather stubborn and is harsh to the majority of the people she interacts with. He is also very strong as well - almost equal to Idate in battle. In spite of his demeanor, however, his personality also has a softer side to it. For example, he took Mafuyu in after finding her and has been acting as a gentle and caring parental figure for her ever since.
