Shiogi Hagihara

Shiogi Hagihara is a student at Sumiyuri Private Academy and the daughter of Noa Origami. Shiogi's personality is similar to that of I's, however she differs from him in that she can live easily by just following the orders given to her, without questioning them or having any conviction of her own. She is a very smart individual, and very proficient at her role of strategist. She calls I's kind an "Aimless Equation" (無為式, Mutameshiki), and describes that as being someone who doesn't fit anywhere and destroys every person they come in contact with. Even with her usual serious and intelligent behavior, she has some moments of vulnerability, like when she got embarrassed when "I" told her that "she has big breasts".
