Kind, sociable, easygoing and a modest to a fault, Rean is about as upright as they come. He is incredibly supportive, often helping people (friends or otherwise) with their various problems, often going through extreme lengths to fulfill requests. He is a natural born leader, often taking the initiative when the group faces a problem, relying on his good instincts and deductive reasoning skills to get through them. However, despite putting on a confident front, Rean has shockingly low self worth. He tends to give out harsh criticism of himself, such as when described himself as a "dropout who's never progressed past beginner level" when prompted about his sword style. He is also unable to reconcile the love that his family has for him, often considering himself a to be a burden, striving to one day "pay back his parents" for caring for them, unable to realize that his parents love him unconditionally.
