Kaiji is a laboratory in which trusting and betraying are boiled down. Kaiji doubts and ends up believing and weeping; Tonegawa and Hyodo cut feeling away and stand at the top. The dice in the basement and the walk along the girders both come down, in the end, to a question about attachment: can you trust anyone?
This page reads 3 Kaiji characters through three layers: MBTI as the outward personality, attachment style as the hidden side, and a Big Five type. Rather than simply assigning a type, Why this type from what they do in the story and where they came from — that is how this site works.
📊 Attachment styles across the Kaiji cast
The comparison baseline is the attachment split across 42,256 quiz responses: 30.1% secure, 15.5% anxious, 13.7% avoidant, 40.6% fearful-avoidant.
Kaiji's back-and-forth — betrayed, and trusting again — is both his weakness and his strongest weapon. Set beside Tonegawa and Hyodo, who are the avoidant pattern finished, the work reads as a controlled experiment in attachment styles.
🧩 Reading the relationships in Kaiji through attachment
Kaiji is a story that keeps swinging between suspicion and trust. A hopeless man and a genius at the last moment live in Kaiji at once: he doubts people and ends up believing them and weeping. Tonegawa removes feeling with the single standard of money; Hyodo consumes other people's despair as entertainment. The extremity of the games works as a device for stripping relationships down to what they are.

MBTI radar (INFP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Kaiji Ito is INFP × fearful-avoidant
Dissolute most of the time, and at the limit betting on a move nobody else would think of — an INFP who lives on ideals and intuition, introverted feeling (Fi).
🎴 Yukio Tonegawa: MBTI ENTJ, attachment avoidant
Teiai Group No.2. A representative of a calm and capable adult who preaches that "money is more important than life."
MBTI radar (ENTJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Yukio Tonegawa is ENTJ × avoidant
Takes a situation as a structure and assembles the way to win, coldly — an ENTJ of extraverted thinking (Te). A world split into slaves and rulers is the avoidant pattern finished: exchanging feeling was cut away as the enemy of efficiency.
🎴 Kazutaka Hyodo: MBTI ENTJ, attachment avoidant
Chairman of Teiai Group. The architect of hell, who finds other people's despair the best form of entertainment.
MBTI radar (ENTJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Kazutaka Hyodo is ENTJ × avoidant
Built a vast group in one lifetime and holds it — an ENTJ of domination, extraverted thinking (Te). He watches people as pieces moved by money and fear, and uses the circuit for connecting with anyone purely as entertainment. The far north of the avoidant pattern: attachment to others cut clean away.
