Tears to Tiara Wiki


When Octavia defeated her in a duel shown in the flashback, she said that she could go crazy and kill or hurt anything in front of her when the sole thought of the incident and the shame has inflicted her. She commented that she would die of her insanity if she were not made Commander of Ruburumu.

She later faces off against Octavia one last time in Episode 11 of the anime. Throughout the fight, flashbacks show that Octavia and Lydia were once the best of friends during their Imperial Training (before the fateful fight in which Octavia didn't kill her). The duel ends with Lydia's death. Her final words to Octavia are asking if she was a good swordsman. 

Along with Gaius, Lidia is a playable unit in the fandisc.
