Mamoru Chiba
Mamoru Chiba first appears as a high-school student studying at Moto-Azabu High School. Before the beginning of the series, his parents are killed in a car crash on his sixth birthday, which revealed the memories of his previous life as Prince Endymion. Living alone, Mamoru befriends school student Usagi Tsukino. In the beginning of the series, dreams of Princess Serenity haunt Mamoru. Unaware of his dual-identity as Tuxedo Mask, he suffers painful visions whenever Usagi becomes endangered, and he transforms unknowingly into Tuxedo Mask. As Mamoru, he tries to piece together his strange dreams, and as Tuxedo Mask, he tries to remember his past and identity, while searching for Princess Serenity. He seeks the Legendary Silver Crystal in the belief that this will fully restore his previous memories. In the anime adaptation, he seeks it because Princess Serenity tells him to in a dream. Of all the characters, Mamoru gets brainwashed and captured the most throughout the series.
