While Ran has no particular interests, she is strong-willed and hates losing, and is the type of person to treasure her childhood friends and family deeply. Despite this, she founded Afterglow as an attempt to rebel against her father, who wants her to inherit the school. Ran has an aloof nature, which hides her loneliness from other people. Deep down, she wishes to become closer to others, but can be socially awkward and has a tendency to trip over her words. She can be easily flustered and is somewhat hot-blooded.
