Rin Tohsaka (Fate/Extra)

Rin Tohsaka (遠坂 凛) is the Master of Lancer in Fate/Extra. She is a different person than the Rin Tohsaka that appears in Fate/stay night, but they are relatives part of the same lineage in the Fate/Extra universe. She is an activist that fights against the Harway family, so her reason to participate in the Holy Grail War is to stop Leo.

Background
Rin is a member of the Tohsaka family that was mostly destroyed in the 1990s. She was active in the Middle East as a freelance engineer as of the 2030s. She was hired by the Resistance and came to be known as a hero after having participated in many liberation wars. Due to her actions, she is wanted by the plutocracy as an international terrorist. She initially worked with hacking & cracking, a data mining team, as an adviser of special technology over a period of three years. She managed to detect the attack on their group, and though she warned the other team members, she was the only survivor. The team prioritized whatever was most important, and due to their different roles, they focused on the equipment and data over their own lives while she escaped.

Their main purpose was accessing the Moon Cell and spreading the means to access it. The data they gathered was placed into a document that spread around, and while normal people could not utilize it, magi used it to enter the Holy Grail War. She gave an interview in the December 2032 issue of Fate/the Fact, an "Internet Deep Culture Magazine", where she explained her role in the group and talked about the nature of the Moon Cell. She was actively pressed into it by her master for public relation activities, and she was paid for doing it. She clearly states that "the Holy Grail War has begun."

Personality
While she constantly puts the Protagonist down and claims that she will not help them, she still provides advice and guides them subtly. She is surprised every time they claim to lack knowledge, but always tells them what they are missing. She thought they simply relied on a powerful Noble Phantasm to win the first round, but claims to have to rethink her opinion of them after learning that they don't even have one.

She is actively against the Harweys and the Western European plutocracy, and even if she wasn't hired by the Resistance, she would still oppose it in her own way. She is against active war due to the potential waste of resources, and would rather focus on the conflict within the Moon Cell.

Role
Rin first appears in the initial selection of the War as a student from class 2-B, known to be pretty, athletic, smart, and classy to all the males who adore her, and a "stuck up Ms. Perfect" to all the females who despise her. Despite being known to some as the most popular girl in the school, the contradictory nature of the area makes some people not know of her. She was not caught by the illusion of the school for very long, having managed to get past the brainwashing more quickly than most.

She chooses to forgo using the school uniform, and begins to examine the area. The initial Protagonist happens to encounter her while searching for the rumor of "Little Red Rooftop" on the school roof. She attempts to inspect his form as an NPC before being warned by the system that direct interference with him is forbidden. She decides to take her leave, and vanishes before his eyes. She encounters Shinji at some point, and becomes physical with him after his aggressive attempts at flirting fail. She is noted by Mr. Kuzuki to be a very strong competitor when providing details to Leo, and they note that the Harways in Asia have voiced some concerns about her. Leo particularly notes that he dislikes her because her unruly behavior is unbecoming for the daughter of a noble family.

She first encounters the Protagonist after the end of the preliminary phase, and begins to study them as an NPC. Upon realizing they are an actual participant, she becomes greatly flustered and apologizes because she thought they looked too plain to be an actual person. She begins to help them after learning that they have no memories, but says that she won't become their ally.

There is eventually an event where the Protagonist must make a choice of coming to the aid of either Rin or Rani VIII. Though both survive the encounter, the "rescued" participant will lose their Servant and aid the Protagonist for the duration of the War. During Rani's path, Rin remains an enemy, and becomes the Protagonist's opponent during the sixth round. After Lancer is defeated, she is stripped of her Command Spells and killed.

Fate/Extra CCC
Rin will appear in Fate/Extra CCC with an alternate uniform. Also Rin is shown to have an extra role on her own story in the game named "Rin Secret Garden". A screenshot shown in where the protagonist will fight her, there's a display of her artwork. The protagonist and his/her Servant must dive into her mind, which divided into a number of levels. There, Rin declares herself as the "Queen of the Moon".

In a screenshot of Fate/Extra CCC ' s opening animation, she's shown to have her left arm ripped off.

Abilities
While Magecraft has died out in the Extra universe, Magic Circuits are still used with hacking. Rin is called a natural by Kuzuki due to how quickly she managed to break through the illusion of Tsukumihara Academy compared to the others. He compares her to a wild among a flock of sheep.
