Rickert is a man in his 40s with a small moustache and short slick-back grey hair. He can usually be seen wearing a nobles' attire, befitting of his position in the Kingdom.
Rickert is shown to be a rather cowardly and ill-witted man. Due to his appearances being rather scarce, we don't know much about him. Having said that, Rickert did express a deep level of dissatisfaction with the Royal Knight Order, saying they shouldn't be trusted with a task of locating the 5th Royal Candidate, as it's far too important for their rank. This also suggests Rickert is a heavy believer in aristocracy and will look down on people of a lower class than him.
During the Subjugation of the Evil Dragon, Rickert was visiting the city of Picoutatte, and was amidst the crowd that ran through the city streets in a frenzy. At some point, Rickert was saved by Razak Gildark, who saved the boy from an impending death, however, he himself died during the process.
- According to the author, Rickert will have a named chapter.
