Kyouka Izumi
ISTJ
Cognitive Functions: Si Te Fi Ne
Dominant Si: Si users are extremely grounded in the reality in front of them. They focus on what already exists and prefer to deal with concrete realities and facts instead of hypotheticals or abstract theories. They often act based on their experiences in the past. (Kyouka was hesitant in joining the ADA even though she really wanted to, because she felt she could only kill based on her experiences in the past. hence her inclination towards present reality rather than possibilities).
Auxiliary Te: Te is about taking objective facts and applying them to the external world. People with aux Te value efficiency, And will take decisions to effectively and quickly complete a given task (how she thought of causing a blackout in the building to deliver the documents to the judge, in her first agency job). Aux Te tend to be more cautious in nature, which we have seen many times to be the case with Kyouka.
Tertiary Fi: The tertiary Fi helps ISTJs have a strong sense of moral (Kyouka was extremely disturbed by the deaths that she caused, even though she didn't really have a choice at the time). Although considering her age and what she went through, the function still hasn't completely developed, making her moral compass somewhat unstable, hence she sometimes shows violent tendencies that would be unusual for a normal person.
Inferior Ne: Ne takes in information about the external world around them and uses it to form many different possibilities, it try to rapidly jump from one thought to another. This being Kyuoka's inferior function, she's not very good at using it. But the function does still exist, therefore kyouka, while not a pro at it, can still deal with unexpected situations (again, the way she handled her first ADA job, as well as the three way war).
