A student in her first year of high school, Sakura is the sister of Shinji Mato. After Shirou's father Kiritsugu died, Sakura often visited Shirou's home to help him with his daily chores. She is outwardly shy and timid, but possesses great inner strength. Sakura has a long standing and obvious crush on Shirou Emiya.
History
Sakura is the biological sister of Rin Tōsaka, and has been in the care of the Matō family for many years. Like most sorcerers, her father, Tokiomi Tōsaka, only chose one daughter to carry on his family's tradition believing that raising an additional child would introduce competition. Zōken Matō, an ancient ally of the Tōsaka House, offered to adopt Sakura, for his own heir, Shinji Matō, who was incapable of sorcery.
In Fate/Zero it is revealed that Kariya Matō, now Sakura's uncle, made a deal with Zōken Matō to win the Holy Grail in exchange for her freedom from Zōken and to be able to return to the Tōsaka family. Kariya was the only member of the Matō family to love Sakura; since Kariya was a childhood friend of Aoi Tōsaka (Sakura's mother), he had become well-acquainted with Sakura and her sister. He was in love with Aoi, but gave up peacefully because she seemed to be happy accepting her engagement to Tokiomi. Since he never received training as a magus (though he had more potential in comparison to Shinji's father Byakuya Matō), he has worms implanted in him to boost his circuits, and underwent accelerated training for the coming war. The worms shortened his life span and constantly weakened body since they are eating away at his magical circuits. Considering his ever weakening body and the large mana requirement required for nature of his servant, a Berserker, it is not terribly surprising that Kariya loses the 4th Grail War, possibly at the hands of his own servant.
Under Matō care, Sakura is subjugated to physical and mental abuse on a daily basis. Zōken seeks to use her as one of his future vessels, empowered by the power of Angra Mainyu. Gathering the tainted fragments of the shattered grail from the last war, Zōken hybridizes the collected black ichor with several of his worm familiars. He implants these parasitic worms into Sakura's body; they drain her Mana but feed on her carnal impulses, drastically increasing her sexual frustration. To curb this aggravation, Zōken frequently instructs Shinji to rape Sakura. Jealous of Sakura usurping his birthright as heir of the Matō House, Shinji continues to brutally rape her of his own volition. Sakura's plum hair and eye color are direct consequences of Zōken's worms swimming through her bloodstream.
Although castigated and humiliated on a daily basis, Sakura maintains her bearings with great stoicism. She fell in love with Shirō Emiya several years ago after secretly watching him constantly attempt to jump a bar (as a track-and-field practice). His staying dedication inspires Sakura to endure her hardships, and her admiration gave her the confidence to approach and assist Shirō after he receives an injury. Shirō's growing relationship with Rin is a source of hatred and envy for Sakura, for she believes Rin to be the cause of all her torture. For the eleven years after her adoption, Sakura grew to resent Zōken for his cruelty, her father for sending her away, and finally Rin, who was unaware of her sister's suffering, for never coming to save her.
Sakura is the principal Master of Rider, who was summoned several days prior to the start of the 5th Holy Grail War. However, under pressure from Shinji and the desire not to fight either Shirō or Rin, Sakura yielded her Master's right to him, although Sakura retains her original Command Mantra.
