Second

The second Regalia wielder. She permanently died during the Nyx quite some time ago, passing on her Regalia to Kosmos. She's also known for having had a thing for Tael. She'll very probably be shown again in Episode Excellion, whenever that is.

Trivia

 * She's originally called "Female Excellion", because Excellion was very damn original when giving her a name and she died before he came up with a better one.
