Kat & Ana

Come from a family of ninjas, named the Iga Clan, which greatly inspires them to practice ninjutsu since childhood and become ninjas themselves when they grow up. Kat & Ana's father left his parents' house when he was a kindergartner to seclude himself in the mountains and develop his self-discipline. Kat & 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.
