A former drug dealer whose real name is Reimucho Hakurei Star. She is a spy who has infiltrated the police, but hasn't been caught yet. Her salary is 50 yen. First person: I (polite). Her pay was cut by 99% plus 1% due to taxes and residence tax caused by the former president (Mai Tanaka's father). She was mistaken for the culprit in the presidential assassination attempt, and although she cleared her name, she was only allowed back on the force on the condition of a 90% pay cut. Since the current president cut police salaries by 50%, she now earns 50 yen. Second person: Koishi-senpai for Koishi, Chibi-senpai for Flandre, and Shion for Shion.

The only daughter of the former US President. Since the president is dead, she is currently Koishi's slave and... a member of the Mission Row Police Station?

Her name was originally extremely long, so she uses a Japanese-style name for simplicity.
