Although Shion doesn't remember anything about her talent, she's known to the masses as the Ultimate Criminologist who single handedly curbed the crime rate of her own prefecture. Compassionate and caring, Shion is quite friendly and loved by all, but she's the farthest thing from a pushover. She may be nice, but she will lecture those who do anything offensive or ill-mannered. While Shion is a sweetheart to others, she treats her younger twin, Tomoya, in a vastly different manner.
