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 various heavy weapons, bombs, and terrorism are rampant—even if people don't die—it seems there is never a quiet day. Basically, since each school has its own disciplinary committee or justice task force, public order in school autonomous districts is left to them, but the Valkyrie Police Academy is entrusted with security in areas where school influence does not reach, or the GSC Defense Office's direct security units step in.
