Kagami Kirei

is a Genin-ranked Kunoichi of Kirigakure and one of the few Genin without being born in a ninja clan. Coming from a wealthy family lineage, Kagami was expected to grow and be trained in the art of business, learning how to analyse and solve problems impacting the families economics. The girl was trained from a young age to understand the art of politics, and this exposure to problematic issues allowed her to subconsciously develop a highly analytical mind, the child being able to process incidents at a rapid speed.

After her parents discovered that Kagami wished to become a Kunoichi instead of following the families business creed, they were taken aback by the suggestion. Her father was completely against such a suggestion, while Kagami's mother was more supportive, and eventually paid for her admission to the Ninja Academy of Kirigakure. Eventually, her father become somewhat supportive of his daughter's wishes, eventually wishing her luck in her Kunoichi career.

Kagami is regarded as the Trap Princess (陥穽姫, Kanseihime), due to her unusual intellectual prowess. Despite being a mere genin, the girl often outperforms the minds of many grown shinobi, as can be easily seen with the traps she is able to produce at a whims notice, using a combination of shuriken, string, and her own chakra nature, the girl is more than capable.
