Shwd Vol. 1 (manga)

Special Hazardous Waste Disposal (or SHWD) has a mission to destroy mysterious biological weapons left behind after the last war. Though SHWD mostly hires men, their newest recruit, Koga, a buff female operative, is assigned to Sawada, the only other woman in the Tokyo branch. Before long, Koga finds herself falling for Sawada, whose powerful psyche compliments Koga’s big muscles. Together, the unlikely duo must confront monsters beyond their wildest nightmares. Office romance meets buddy cops meets yuri horror!
