Anna Katsuragi (桂木あんな, Katsuragi Anna) is a young student of Tomobiki High School.


One day, she is accosted by Sōban and his flunkies from Butsumetsu High School who demand her money, but Lum zaps them for her. As the two walk together, Anna feels that Lum has an advantage over people like Sōban and his gang since she can fly and shoot electricity, however, Lum explains that anyone could beat Sōban with courage even without her powers. Anna takes it to heart so much that she issues a challenge to Sōban that Lum will fight him without using her powers. At first, Lum was shocked at this, but was willing to go through with the fight to make Anna believe in the power of courage. However, on the day of the fight, Lum secretly brought some strength pills, and Anna ends up discovering it as Lum lost a majority of them during the fight. In the end, Lum was unable to defeat Sōban, but Anna nevertheless thanks Lum for showing the importance of courage.

    • 杏奈 - "apricot" (杏) (an) and "apple tree" (奈) (na).
    • 安奈 - "peace, quiet" (安) (an) and "apple tree" (奈) (na).
  • Anna's surname Katsuragi means "Japanese Judas-tree" (桂) (katsura) and "tree, wood" (木) (ki/gi).
