Reki is the Sniper department's ace. Butei rank S. Her real name is unknown. She's habitually taciturn, constantly impassive and indifferent in fashion. She's always seen with a large headphone over her head. Her signature quote is "I am a single bullet. It has no heart. Therefore, it does not think. It just flies straight towards its target", which she always says before she shoots her target. She can shoot anything without missing her target within 2-kilometer radius. Her personal weapon is a Dragunov sniper rifle. She apparently listens to the sound of wind from her homeland using headphones in order to keep her soul intact with it.
