Milo

A descendant of humanity from the far future, which has been destroyed by a pandemic. One of the few humans who was resistant to the Revisions. She is an agent called a "Balancer" who works for the organization AHRV, which protects the future where humanity still survives. She has strong feelings of hatred towards the Revisions for their massacres of AHRV's members, and devotes herself to the organization entirely. Emotionally inexpressive, she lives a logical, orderly life.
