This page reads the 6 members of Tokai OnAir 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 has been said publicly and from public episodes — that is how this site works.

🧩 Reading the relationships in Tokai OnAir through attachment
Every member of Tokai OnAir has stated their result, and every one of them is a different type — an unusual arrangement. In a group built on set-piece projects, the division into the one who has the idea, the one who keeps it moving and the one who holds it up tends to come out clearly. Some members have also said publicly that their result changed at different times, so both readings are given. The attachment column is the editors' reading.
