Two centuries ago, the Tohsaka House, in collaboration with the estates of Makiri and von Einzbern, helped found the Fuyuki Holy Grail Wars. Although the other noble families forgotten their original intention. Tokiomi still follows his ancestor's desire to reach Akasha, or the root of all knowledge. He is the fifth generation head of the Tohsaka family.
He and Risei Kotomine are close acquaintances; through Risei, Tokiomi meets the young Kirei Kotomine, Risei's son, whose command spells have appeared three years prior to the start of the Fourth Holy Grail War. The two men arrange for Kirei to be transferred from the Church into the Magi's Association as Tokiomi's pupil while leaving Kirei uninformed as to the true nature of the marks on his hand. They both intend to use Kirei to make sure that Tokiomi will obtain the Grail and that Kirei's role is to provide Tokiomi with additional Command Spells and another Servant. Like Risei, Tokiomi holds Kirei in high regard in terms of ability and character but has little understanding of how empty the young man feels.
He is married to Aoi Tohsaka, the childhood friend of Kariya Matou. Tokiomi leaves his estate in the hands of Rin, whom he intends to be his successor. Though Tokiomi originally hoped to give his daughters a choice as to whether or not to become magi, just as his own father had given him, both Rin and Sakura had unusual amounts of innate ability for magi. Without the protection of a magus family and the training to control their abilities, this potential could cause dangerous supernatural events to befall the girls, or lead to their capture by the Association to use as specimens. As the Tohsaka family's protection and magecraft could only be bestowed upon one child, Tokiomi allowed Zouken Matou to adopt Sakura, as the Matou family had a need for an heir. His sudden decision to give Sakura away comes as a shock to Aoi, though she does not openly oppose his decision.
Tokiomi is an archetypal magus who, as all magi strive to do, wishes to reach Akasha. Although he loves his wife and cares for his daughters, he bases everything on his and their lives as magi, foregoing their happiness as regular people and only thinking of their future lives as magi. He has a "perfect and coldhearted" aspect to him that can be called a negative trait to his otherwise seemingly outstanding self-image. It is such a strong trait that it would have guided Rin's life if she were to ever understand that aspect of him. His "charm point" is his goatee, and he spends a long time grooming it daily.
Much to Tokiomi's displeasure, his arrogant and materialistic Servant Gilgamesh has difficulty acting covertly and obediently. In turn, Gilgamesh dislikes his Master, whom he considers boring, and is intrigued by his apprentice Kirei Kotomine's participation in the war.
The design turned out completely different from Takashi Takeuchi's original image of the character, but he feels that he cannot picture Tokiomi any other way. Urobuchi was hesitant about killing him off because Rin inherits her kindness from him, so he sought to put Tokiomi in a villainous position. When Rin eventually receives the Azoth knife that killed him, Takeuchi feels that only those who can watch the story like gods can feel something akin to the sense of inconstancy in life.
When Kariya confronts Tokiomi regarding Sakura's adoption, Tokiomi only declares that he can think of nothing greater than for one daughter to be renowned as a legendary victor and her sister to be known as her formidable opponent. Towards the end of the war, during Tokiomi's visit to Rin, his true intention behind adopting away Sakura becomes apparent. Aware that both his daughters possessed exceeding rare sorcery traits: Rin possessed all five elements while Sakura, though lacking all five, possessed Imaginary Numbers, Tokiomi knew that the daughter he did not train as the Tohsaka successor would be manipulated and used because of her unusual nature. In order for Sakura to fulfill her innate potential to become a powerful mage, Tokiomi wanted Sakura to learn the magecraft of the Matou family, so that she would be able to protect herself from others wishing to use her as a result of her lineage.
Near the end of the war, Tokiomi attempts to form an alliance with Irisviel von Einzbern and Saber in order to better dispose of Rider. While they are unwilling to form an alliance with him, a truce is called between them until Rider and Berserker are destroyed. This truce was contingent upon Kirei being exiled from Japan, much to Tokiomi's shock. While reluctant, he agrees to do so with Kirei's consent upon hearing of Irisviel's reasons for disliking Kirei.
Considering him to be a loyal apprentice, Tokiomi gives Kirei an Azoth Sword as a parting gift, only for Kirei to murder him by stabbing him in the back. This is the same knife that is passed onto his daughter, Rin. Because of his untimely death, he was unable to tell Rin about the original goal of the Holy Grail War to open a “hole” beyond the World.
In the Prologue, the clocks were set one hour fast by Tokiomi when Rin woke up, but she only remembered them being 30 minutes fast. Rin suspected it to be some trick of her late father’s, a bit of playfulness on his part, seeming to say “if she can’t even notice a slip-up as trivial and close to home as this, it’s too soon for her to fight in the Holy Grail War.”
Rin gives the Azoth knife to Shirou which he ironically uses to kill Kirei in the Fate scenario.
Kirei reveals to a captured Rin that he betrayed and murdered Tokiomi in the Unlimited Blade Works scenario
Tokiomi, as the head of the Tohsaka family, has mastered the principles behind their jewel based magecraft in conjunction with his own fire attribute to become an effective battle mage. Using a staff topped with a jewel into which he has stored magical energy for many years, he can summon elemental spells in combat instead of the more simple jewel detonation used by Rin. He is also shown to be capable of manipulating air currents to land from a great height and despite the elemental difference, performed an ice based magecraft whilst teaching his daughter, Rin, how to use jewel magic.
He is an expert in Flame magecraft (炎の魔術, Honō no majutsu?), he can manipulate his flames into barrier and by chanting "Intensive Einäscherung", it creates a flame thrower attack on the opponent.
In addition to this, his apprentice Kirei Kotomine was taught the basics of Reinforcement, Familiar usage, Divination, Spiritual Evocation, Alchemy, Summoning, Necromancy, and mastered Spiritual Healing, indicating that Tokiomi had a working knowledge of those skills.
Tokiomi does not seem to believe himself a man of particular talent, but at the same time has the pride of a magus and follows an unerring path of elegance in all things. To this end he rarely shows anything but a calm demeanour, showing no hint of worry when faced in battle by another magus.

Comment for Tokiomi
Takeuchi: He was a character whose image changed 180 degrees from what I hat thought in the early stages. However, now he has become a character who can't be pictured any other way
Urobuchi: Since Rin inherited her kindness from her father, I was given some hesitation about killing off his character, and so I ventured to put him in the position of the bad guy. However, by personal standard, he's a traditional person without a single thing wrong about him.
Takeuchi: The Azoth Dagger that took Tokiomi's life. During the episode when Rin received that, only the people who view the story from a position like that of a god can feel something akin to the sense of inconsistency in life.
Urobuchi: As he watched over Rin pour magic into it as it were valuable, Kirei was most likely coldly smirking.

Tokiomi Tohsaka [Person's name]
The fifth Tohsaka family head. Had everything gone according to plan, he would have been the man to finish the Holy Grail War once and for all.
He started making preparations for the Fourth Holy Grail War long before it ever began. But although he had set up everything perfectly in his favor, he was tragically killed by his trusted ally, Kotomine Kirei. Well, seeing as how the one who tempted Kirei into defecting in the first place was Gilgamesh, in a sense you could say Tokiomi died due to a lack of compatibility with his Servant.
Tokiomi and his predecessor made a conscious effort to commercialize their spiritual lands, and the unnatural economic success of every business situated there naturally led to exorbitant rental fees, which were collected by the Tohsaka. Of course, as far as Tokiomi was concerned, the fact that the "harvests of all the tenant farmers tilling the Tohsaka land" were protected from bad luck and natural disasters by the Tohsaka's careful management of the ley lines, meant that taxing them like this was his natural right. Truly, it was a 20th century feudal system made possible through sorcery.
Although, even among the Second Owners of other lands, very few have ever seen monetary returns like those made by the Tohsaka.
After Tokiomi's death, these assets were passed on to Aoi, and after Aoi's death they were passed on once more to Rin. Or at least, they should have been, but thanks to her legal guardian Kirei's naïve honesty and crude management, most of the valuable property was lost to other people. Then again, as a priest who values honest poverty, he probably thought it would be good for her from an educational standpoint. Just another thing for Rin to wallop him for, I guess.

Rin Tohsaka [Person's name]
The eldest daughter of Tohsaka Tokiomi. The younger years of one of the heroines of Fate.
10 years ago, Rin’s understanding of the Holy Grail War was about equal to that of Shirou’s during the Fifth War. That is, it seemed like she understood but she really did not.
In the eyes of young Rin, her father Tokiomi was a great magus who must be respected and loved, but as for the coldheartedness that accompanied the ideal, that was a negative aspect of his personality that she failed to understand.
If Tokiomi had survived until the time when Rin could have really understood her father’s personality, it would certainly have deeply affected the development of her own personality. Whether she would oppose that inhumanity and leave the path of thaumaturgy, or whether she would become a “perfect and coldhearted” witch like her father – no matter which one, this parallel world, for Rin, would certainly be one far away from happiness.

Q: Why is it that Tohsaka Rin didn’t know about the original goal of the Holy Grail War to open a “hole” beyond the World?
Q: Why is it that Tohsaka Rin, as the legitimate heir to the legacy of the Three Houses, didn’t know about the original goal of the Holy Grail War to open a “hole” beyond the World? I would have thought that the Tohsaka family would have kept some records regarding the true nature of the Holy Grail War. ...Could it be that Rin just never saw those records?
A: It was because of her Papa’s untimely, careless death.
 Fate/complete material III: World material - FAQ with Nasu: General Questions about Fate, p.130
Q: In the Prologue, the clocks were an hour early when Rin woke up, but she only remembered them being 30 minutes fast... why is that?
Q: In the Prologue, the clocks were an hour early when Rin woke up, but she only remembered them being 30 minutes fast... why is that? She did suspect some trick of her late father’s, though (laugh). Could it be that Rin, being the idiot she is, forgot about the first time and set her clock 30 minutes fast twice?
A: The clocks being one hour fast was a scheme of her late father Tokiomi. A bit of playfulness on his part, seeming to say “if she can’t even notice a slip-up as trivial and close to home as this, it’s too soon for her to fight in the Holy Grail War.” I have to admit, it’s a little different from the perfect gentleman Tokiomi was portrayed as in Fate/Zero (laugh)
Ｑ：プロローグでは凛の目覚まし時計が1時間早くなっていましたが、 彼女は30分しか早めた覚えがない……その原因は？凛は、亡父のイタズラを疑っていましたが（笑）。 やはり大ボケを噛ます凛が、一度目を忘れて“2回”時計を30分早めただけでしょうか？
