Kat and Ana

Kat and Ana are major human characters in the WarioWare series. They are ninja twin sisters who adore nature, especially animals and flowers. Their house is located in a park in Diamond City. They attend both the Diamond Kindergarten and the Mystical Ninja Elementary. Their names are a pun on the word "katana", a type of Japanese samurai sword. They come from a family of ninjas, named Iga Clan, which greatly inspires them to practice ninjutsu since childhood and become ninjas themselves when they grow up. Kat and Ana's father left his parents' house when he was a kindergartner to seclude himself in the mountains and develop his self-discipline. Kat and Ana planned to do the same, but abandoned the idea after playing a game of living by themselves for a while. However, Kat still expresses her resolve to go through this training.
