Augustia

The Magician of August / The Conqueror Magician

The fallen empress of the August world who died protecting Augustus, her younger brother Magician. The August world is overrun by monsters called Nightmares which wiped out humanity, so Augustia wants to return as soon as possible in order to protect Augustus. This means stealing Wynrou's Reincarnation Control powers, even if she doesn't have the mental strength to endure it.

Once having led humanity in the August world with her older brother Gaius, her world literally fell apart after his death. Too harsh on herself and constantly comparing herself to Gaius' near-perfection as a leader, Augustia wonders why she was the one who survived only to see humanity crumble under her watch.
