Wriothesley is a cunning and intelligent man despite his young and intimidating appearance, he can be pretty playful and sarcastic at times, has an addiction to teas, and often takes necessary actions to ensure the safety of the inmates in Fortress of Meropide even if such actions may make him look like the villains in the eyes of others. Nonetheless, he upheld his duty as the administrator of the Fortress of Meropide. His manner of speech is rather casual and lax despite being the head warden.
