Reki, also known as Sniper Department's ace, holds rank B in Beitei. Despite this, little is known about her real name. She tends to be reserved and unresponsive, often appearing indifferent in appearance. Her signature quote, "I am a single bullet. It has no heart. Therefore, it does not think. It just flies straight towards its target," is always spoken before she shoots her target. Reki's exceptional marksmanship allows her to hit any target within a 2-kilometer radius without fail. Her preferred weapon is the Dragunov sniper rifle. Through headphones, she listens to the sound of wind from her homeland in order to maintain a connection with it.
Reki is descended from Minamoto no Yoshitsune and Gengis Khan, and hails from a tribe in Mongolia, referred to several times as the Ulus. She lived with 46 other females in seclusion. Why she was released and not the others is unknown. Reki is part of a family that appears to have an interesting flaw. Her tribe apparently has a genetic problem that takes effect on the pregnant women of the civilization. As such, only the female gender will be born to the tribe.
"Sweeper" is mentioned by Jeanne, where it is implied that she has actually performed as a Butei assassin.
As such a result, Rekis tribe is constantly on the lookout for strong males to introduce into the Ulus, in the hopes to make their descendants stronger. This becomes clarified in the Epilogue of Light Novel Volume 6. Reki is the Snipe departments prodigy, and her proficiency in the field has been mentioned numerous times in the past. However, due to her skill, she seems to have performed "unrecorded" jobs in other countries, namely Russia and China.
