A chaotic class of 10 MBTI types!
About
――――――――――――――――――――――――
What if your classmates' personalities
were their MBTI types personified?
This was supposed to be an ordinary high school...
In the classroom, there's the way-too-free ENTP. INTJ, who wants everything to go according to plan. ESFP, who drags everyone into their pace. And for some reason, a group that causes incidents every single day.
Yes, this class is a gathering of 10 personified MBTI types.
Classes, breaks, after school, school festivals, romance, fights, friendships—. It was supposed to be a normal youth, but with such clashing personalities, every day is an uproar!
"Do we really need to do that now?!" "No, this is just the kind of person I am." "Wait, someone stop them!!" "...Looks interesting, doesn't it?"
Values, vibes, and ways of thinking are all over the place.
An unpredictable school life brought to you by 10 people with way too much character.
What kind of days will you spend in this class?
MBTI High School, start!
