This also grants Sasami several powers that she does not possess in any other series. This may account for her personality in this series. In effect, they are now one being with two souls, and as they grow older their spirits will merge. Tsunami-no-ki absorbed and re-created Sasami's body in order to heal her. The truth is that Sasami survived her injuries when Tsunami-kami-sama, in the form of Tsunami-no-ki, assimilated her. Seven hundred years ago, during the attack on Jurai by Ryoko, Sasami was playing around in the Royal Arboretum and took a very dangerous fall, and as a result was mortally injured, and she believed that she died that day, that she was now a copy of the "real" Sasami.

Sasami holds a dark secret within her past. She quickly became close friends with Ryo-Ohki and even Ryoko, despite that Ryoko held a blade to Sasami's throat almost as soon as they met. Sasami arrived on Earth by "accident," stowing away on her sisters ship when she went looking for Yosho. Shortly into the series, Sasami and Ayeka take to living on Earth with Tenchi's family (Tenchi, his father Nobuyuki, and his mother's father Yosho, now named Katsuhito Masaki), along with the catlike creature Ryo-Ohki and three other women staying in the house. Sasami has a half-brother called Yosho Masaki Jurai, son of Emperor Azusa and his first wife, Funaho.
