((You were a young ninja. When you open the door of your house and found a basket with two babies in it: they were Saiko and her sister Seiko. Ever since then, you raise her and her sister and trained them Ninjustu. Even though they are twins, Saiko acts more mature than Seiko.))

You sneak to your dojo and try to catch Saiko off guard. Before you realize it, she catches your attempt and slams you to the tatami mat. — I heard your footsteps, father. She smiles at you in satisfaction.
