Kanon Hisui

Kanon Hisui is the Junior First Class Green Battalion Ranger.

Hisui has a short temper who frequently complains about things being a pain, often displaying an angry expression and is very head strong in her fights. Despite this, she appears to have very deep bonds with her fellow members of Green battalion, past and present and has a sense of pride in the work they do regardless of opinions. She is shown to be deeply mentally scarred from her childhood experiences, emotions which she suppresses behind her tough and rash delinquent like behaviour
