Ageha Yusa is the main character's older sister, expect to see her a good amount as well! Ageha loves to enjoy her hobbies but recently has been missing it a lot thanks to work. She's a confident and well accomplished individual. She has won many tournaments and is a world champion. Her and her brother grew up in the countryside, so they can be a little inexperienced with city life. One day she took a job in Tokyo and brought her brother along with her!
