Disclaimer: I make no claims to the accuracy of this MBTI since it was created working from a combination of very limited historical facts and my own headcanons and interpretations.

Also, it's important to understand that the MBTI measures preferences when functioning without significant interference. This makes Izo more complicated to type because his natural preferences were functioning under interference for most of his life. Shame and negative feedback don't change underlying type but affect natural preferences in ways that may not even be obvious to Izo himself.

I — Introversion

This dimension looks straightforward but may actually be the most complicated of the four to score.

There is substantial evidence for introversion: Izo becomes quiet when conversations move toward introspection, articulation of internal states, and individual thought. These are not things he's very good at. He won't join others in dancing and singing at the tea house or in the pleasure quarters. He tries not to draw attention to himself outside the dojo. He manages difficulty by becoming invisible rather than seeking company. He blushes and finds it embarrassing, which is physiological but also the response of someone who experiences being seen as being exposed.

Evidence suggests that pure introversion is also present: He is outgoing and excitable about swordsmanship, stories, and his own experiences. The boys at the dojo knew him as kind rather than scary. He enjoyed teaching. He had, in childhood, the physical social ease of someone who gathered other boys around him for river fishing, stick fights, and games. In Katsu Kaishu's household he engaged and participated.

What this describes is not introversion in the simple sense but a person whose extroverted tendencies have been progressively suppressed by consistent negative feedback. Being called stupid, accused of bragging when he talked about swordsmanship, learning that drawing attention to himself outside limited safe contexts produces outcomes that are worse than simply staying quiet.

His natural preference is likely closer to the introverted end of the spectrum. He recharges alone, processes internally, and is a private person in the fundamental sense, but the degree of withdrawal visible in the adult picture is some combination of learned behaviors and armor to protect himself.

S — Sensing

This is the clearest dimension to score.

Izo is concretely sensory in his orientation. His intelligence operates through specific, tangible, present-focused channels. His memory is exceptional for particular details: places, dates, small things, sequences of events, sensory anchors to a given moment. He can describe what happened with precision but struggles to establish meaning in the abstract sense. He is strategic through concrete application as shown in playing Go and swordsmanship, not through theory.

He has no interest in politics, which represents the most abstract ideological framework of the Edo period, and this is both consistent and well-documented. He followed Takechi and joined the Kinnoto without any interest in the sonno joi movement because the existing relationship with Takechi provided a concrete anchor. He is motivated by specific and present realities rather than abstract principles.

His learning difference is also relevant. The difficulty is with kanji, which represent words in the abstract, requires a layer of symbolic processing that does not come easily to him. Hiragana, which represent sounds, are more accessible. This is consistent with a strongly sensing orientation: the phonetic is more accessible than the symbolic, the concrete sound more accessible than the abstract representation.

His self-awareness, when it surfaces, is somatic before it becomes cognitive. The nausea after the first murder is an example: his body tells him things his mind cannot access.

F — Feeling

This dimension is difficult to scare because it is most obscured by the damage that has been done to him over the years. On the surface, a clinician may note his flat affect, difficulty naming emotional states, and tendency to route feelings through external descriptions. This may read as thinking-dominant processing, someone who is detached, analytical, and unemotional, which is not the case for Izo.

He adult life is organized around the relational and emotional debt to Takechi Hanpeita. He stayed through conditions no thinking-dominant person would have found persuasive. The calculation that kept him with Takechi was not logical but emotional: gratitude, infatuation, and the believe that loyalty was owed regardless of cost.

He cared about younger students at the dojo and consistently encouraged them. He told his little brother ghost stories. He asked to speak to Takechi from his jail cell even after the poison plot, some part of him still hoping for an explanation that would make sense. These are not the behaviors of a thinking-dominant person.

However, his feeling function has been extensively suppressed and shamed over the years. Expressing feelings produced negative feedback, showing enthusiasm was admonished as bragging, needing things was burdensome. So the feeling went underground where it continued to operate as the primary driving factor behind his behavior even though it was almost entirely unavailable to conscious verbal processing.

This difficulty naming emotions is not evidence of thinking preference. It is evidence of a feeling-dominant person who was taught repeatedly that his feelings were not safe to express or examine.

A thinking-dominant person who cannot access emotions is operating at their natural limit. A feeling-dominant person who cannot access emotions is operating in suppression, and suppression can be, slowly and carefully, lifted.

P — Perceiving

Izo left Kyoto for Edo without a plan. He left Katsu Kaishu in the middle of the night without a plan and returned to Kyoto, also without a plan. He spent months following this improvising his survival from one day to the next. None of this speaks to a judging-dominant preference for structure, closure, and advanced planning.

Most of his life has been structured by external authority rather than internal planning: Takechi, the Kinnoto, or the situation decided what he did and when. The fact that he adapted each time is perceiving behavior: flexible, responsive, present-focused, and comfortable with improvisation even when improvisation is uncomfortable.

He is disciplined in his swordsmanship, which might read as judging, but the discipline of training is different from the judging preference for external structure in daily life. Many highly disciplined people in specific domains are deeply perceiving in their broader orientation; it is the domain that provides structure they don't generate for themselves.

The Go game he learned from his mother complicates this slightly. Go requires forward planning. But Izo's approach to Go emphasizes memory and learning from past games over advance planning. He avoids repeating mistakes rather than engineering outcomes. That is more consistent with perceiving's experiential learning orientation.

The Type: ISFP

ISFP types are persons with deep individual values, strong loyalty, genuine care for others, and a rich inner life that is not readily visible from the outside. ISFPs experience the world through the senses, make decisions through the feeling function, and express themselves through action and presence rather than words.

ISFPs are notoriously difficult to read. Their warmth is real but they express it through behavior rather than articulation, through showing up, remembering, small specific attention to someone else's needs, and not verbal declarations. A partner or colleague who expects the feeling to be named will consistently underestimate how much of it is present.

ISFPs have strong values that they hold quietly and act on without explanation. Izo's loyalty to Takechi, held through ten months of torture, is exactly this: a value so deeply embedded it requires no justification or examination, acted on without announcement until it broke. An ISFP's values are not negotiable but they are also not always visible.

ISFPs are present-focused to a degree that reads as lack of ambition or direction. They are not building toward the future but are attending to the present. This is consistent with Izo's apparent absence of political ideology or long-term ambition: he was not strategizing toward a future Tosa or a restructured domain. He was doing what was in front of him, for the person who was in front of him.

ISFPs are physically oriented and find self-expression through the body. Swordsmanship as the primary domain of Izo's competence and identity is consistent with this. The physical ease in Katsu Kaishu's household, the ability to sit with someone in comfortable proximity without needing to fill the silence with speech, is consistent.

ISFPs are sensitive to criticism in ways that are not always apparent because the sensitivity is managed internally rather than displayed. They absorb criticism without visible reaction and process it in private, which can look like toughness and is the opposite. Izo absorbing being called an idiot and absorbing the stray puppy comment without complaint is not resilience. It is the ISFP sensitivity operating under suppression, processing everything in the interior.

ISFPs are loyal to a fault. The fault is visible throughout his history.

The Shadow

MBTI theory also describes shadow functions, which are the less developed, less conscious dimensions of the type that emerge under stress and produce the most problematic behavior.

The ISFP's inferior function is extroverted thinking: systematic, logical, external-world-structuring reasoning. When an ISFP is under severe stress, the inferior extroverted thinking erupts in distorted form as rigid, catastrophizing, convinced of total failure, and unable to access the flexibility and feeling-orientation that normally governs the type.

This is exactly what happens when Katsu Kaishu's silence is misread. The normal ISFP flexibility, the present-focused relational intelligence, is replaced by a distorted logical conclusion: I am not adequate. I need to leave. I am causing harm by staying. The logic is wrong but executed with the inflexible certainty of shadow thinking, and produces the middle-of-the-night departure with no possibility of return.

The inferior function eruption also explains the specific quality of his self-punishment: it is not emotionally chaotic, which might be expected from a feeling-dominant type under stress. It is coldly, rigidly logical. I deserve this. I did something wrong. These are not feeling statements. They are the distorted thinking delivering verdicts with certainty he does not apply to anything else.

She’s intelligent and introverted but can be headstrong and a leader when she wants to be. It just depends what mood she’s in on the day and whether Buffy’s there to not make her feel like she’s less than what she really is.

I was a bit surprised. I know the 16 personalities is not really that accurate, but still! Though I was like at 59% thinking and 53% judging so maybe on a different day it would be ISFJ or ISTP or ISFP. But I did think this was somewhat accurate.
