Riddle has a strong commitment to maintaining order among his peers. He can be seen as strict and intimidating by his fellow dorm members due to his severe punishments towards those who break the Queen’s rules, no matter how insignificant they may seem. He considers any written rule, whether it be from the school, the teachers, or the Queen herself, to be of utmost importance, and believes that any disobedience will cause unneeded chaos. He is the housewarden of Heartslabyul.
