She goes to Ichou Academy (another branch school of Hiiragi Academy). She managed to get her brother a job as a teacher in his alma mater, thus beginning the plot of the story.
Suzune's hair color is blonde and eye color is blue, this being the only physical trait shared by her and Junichirou. Her outfits generally vary between her school uniform (a short blue dress with long puffed sleeves and white cuffs, a white sailor collar and a short white tie in the centre of the bodice) and her casual attire (A pink singlet and a pair of plain denim shorts with a plain brown belt.)
Suzune has a very lively and active personality. She is often the one taking care of her brother, telling him to do something or to wake up. She cares a lot for her brother and is a likable and kind person who seems to get along well with her classmates.
