Subaki is a self-professed perfectionist, a fact that primarily stems from the legacy of his family's traditions, ones that have conditioned him to strive towards achieving perfection in all that he does. As a result of this, Subaki is known to be very demanding and even unforgiving towards himself as he works tirelessly to meet the harsh expectations that he sets for himself. This has in turn caused him to have the tendency to engage in self-reproach whenever he commits "offences" that he feels make him appear weak and imperfect in the eyes of others. During such occurrences, Subaki is known to lapse into a state of flustered distress as he attempts to rectify his shortcomings.
