A masterful tactician that utilizes whatever she can to get the job done: Shiogi Hagihara. Carrying out any order given to her without question, she is a fearsome individual. She is an excellent marksman as well, who was able to handle a sniper rifle at 11 years old and take out targets who were over a kilometer away. At Sumiyuri Private Academy, she is one of the top students. As a trained assassin, Shiogi is quite formidable with her job, even at a young age. Being intelligent, a master of martial arts, and proficient with her role, she is quite the strong assassin. Ii and Shiogi have a somewhat similar personality, though she has no trouble with living by simply following orders. Though she is often serious and radiating a bewitching aura as the edge of a katana, there are moments where she can get flustered, such as Ii complimenting her breast size.

Spoiler

Shiogi is the daughter of Noa Origami, which Ii learns after she figures out that her mother was killed through backwards thinking. Upon learning her mother is dead, she freaks out and loses an arm to Ichihime's string. She then charges Ichihime and is subsequently sliced into pieces.

Spoiler

Shiogi has had a number of jobs, including assassinating the Zerozaki, protecting Iria Akagami from the Zerozaki clan, and finding Ichihime.
