As the Chief of Defense for the Kivotos General Student Council Administrative Committee, she is tasked with maintaining public order throughout Kivotos. However, since Kivotos is a place where bullets fly and heavy weaponry, bombs, and terrorism are rampant—even if people don't technically die—it seems there is never a quiet day. Basically, since each school has its own disciplinary bodies like the Disciplinary Committee or the Justice Task Force, security within school districts is left to them, while the Valkyrie Police Academy or the GSC Defense Office's direct security units handle areas outside school influence.
