The opening of Tenchu ~Yami no Shioki Nin" is when Sana/Yuriko Ono saves a bystander in a crowd who became hostage to a mad-man wielding a cooking knife. Sana has no where to go to, Seiko Murata/Pinko Izumi takes her home to her house to show her hospitality. Sana hasn't seen a modern toilet and doesn't know how to use it. Seiko teachers her how, and also day to day duties. Sana has this "Justice" mentality: There are too many unforgivable people in this world, and she vows to defeat them in the name of God.
