In addition to training to be a super hero, Katana also follows the noble warrior traditions of the Samurai. Now a mysterious presence has given her the responsibility of guarding a hundred ancient Samurai swords--but why her, and for what purpose? With the help of Wonder Woman, Supergirl, Ms. Martian, and some of her other super friends, she intends to find out. But she just made captain of the fencing team, she has a huge school project due, and a villain with ties to her family's past seems to be amassing an army.
