Keiko Alteridem (Triumph)
Background
It was 1984 when Keiko Alteridem and her husband, Theo, escaped Praetorian Earth by magical means. Keiko soon fell in with the heroic side of Paragon City's magical community, and was frequently seen to assist MAGI and the Midnight Squad. Keiko and Theo adopted a son shortly after their arrival, and in 1987, Keiko gave birth to twin daughters, who she and Theo named Megan and Cyril.
During this period, Keiko fought against Rosa Kreuz on several occasions, becoming increasingly frustrated at her inability to counter Rosa's apparently-magical self-resurrection ability. To this day, Keiko is working to insure that Rosa remains underground the next time she's buried. In addition to her fights with Rosa Kreuz, Keiko battled against many of Paragon's criminal factions, and gained a notable animosity towards the Circle of Thorns, which she still harbors.
Keiko Alteridem very rarely speaks of her life before escaping Praetorian Earth, so information regarding how she began learning either magical or martial arts is not available. Keiko has passed her arcane knowledge to her daughter, Cyril, and trained her son, Beckett, in the ways of the sword.
Current Status
Keiko Alteridem very openly lives two lives. On one hand, she is a devoted wife and mother, who raised three children to adulthood and made them into upstanding members of society. On the other hand, she is a powerful and dangerous hero, who frequently battles, and often dismembers, villains who threaten society. She maintains a close friendship with Chihiro-san, and the two often engage in various magic-related pursuits. Keiko is also deeply involved in the workings of the Alteridem Foundation, which she was instrumental in forming. She maintains a number of contacts within Paragon's magical community, though she has fallen out of favor with MAGI, having repeatedly and publically criticized Gregor Richardson's apparent inability to notice when MAGI's vault is being robbed despite spending all day standing in front of it.
Personality
For the most part, Keiko Alteridem is sweet, kind, and gentle. Those who make her angry, however, discover her more dangerous side, the side that prompts her to light herself on fire as a means of self-defense, and to take up katana or other cutting weapons and use them as designed.
