Steins;Gate: Makise Kurisu [ISTJ]

Introverted Sensing (Si): Kurisu is a great scientist not just because of her intelligence, but also because of her attention to detail. She methodically collects data and analyzes it based on her knowledge and research. Even when discussing complex theories she takes everything a step at a time. Kurisu finds it very difficult to let go of the idea of reconciling with her father. Her subjective experience means that she fails to see how unstable her father really is, and eventually it gets her killed. (Sort of. Time travel)

Extroverted Thinking (Te): Kurisu won't believe in anything that she can't verify, but once shown evidence, she accepts the facts. She believes time travel to be impossible, but must accept it once she sees evidence. It is not Okabe, but Kurisu who explores the various time travel theories, building intellectual models to better understand them. She then uses this information to stratagize and achieve results that Okebe cannot reach on his own. Kurisu approaches unorthodox situations like altering the past and future more or less calmly. She simply looks for ways to manipulate the situation in order to gain knowledge and solve problems like Mayuri's death.  

Introverted Feeling (Fi): Kurisu is often sensitive and emotionally vulnerable. She is easily embarrassed by Okabe's verbal jabs, but also doesn't like to show how much they bother her. She avoids giving any indication of how much she cares for Okabe until the last minute, turning to Te sarcasm and aloofness instead. Kurisu often questions the ethics of their experiments, not wanting to be responsible for damage caused by the "butterfly effect." 

  

Extroverted Intuition (Ne): Kurisu has a healthy Ne that she applies to complex scientific theories, reaching accurate and detailed hypotheses in abstract fields like time travel without too much effort. Even though she thinks abstractly, Kurisu never jumps to conclusions, holding her intuition in check with the more reliable and verifiable Si/Te. Unlike some Ni users, Kurisu accepts evidence that doesn't fit with her own theories relatively easily, even abandoning her most cherished scientific beliefs when they are contradicted by Okabe's experiments.
