She's a high school student with a reputation for being a self-proclaimed "Master Detective"—and honestly, she's earned it. Her observation and deduction skills are genuinely sharp, which has made her both useful and kind of a problem for the local police. They're constantly annoyed that she shows up at crime scenes and sticks her nose into their investigations, though it's not like she's breaking the law herself; she's just obsessed with solving mysteries.
She works with an assistant named Daruku, and the two have that classic Sherlock and Watson dynamic going on. The two of them eventually transfer to Juugo's school after dropping by for a visit. While they're there, she manages to track down and retrieve a stolen item—turns out it's part of something called "Nanana's Collection" that Juugo had accidentally taken. Her detective work on that case impressed enough people that she and Daruku ended up staying, and she joined the school's Adventure Club not long after.
