The most unrealistic thing about cote is not Ayanokoji
For me the most weird thing in the series is the amout of geniouses per square meter in that school.
IRL when I was in high school, people that scored 90/100 in my school could be counted with one hand, in cote tho, every class has at least 5 of those. People good in a figth were more common but not with martial arts, we only knew street figting. Also in my country people in that age group was more worried about drinking and not getting pregnant than with studing xD.
That's why I love this series so much! Is so diferent from what I experienced that it pulls me in in an instant. Also bro all the girls in cote look like super models while IRL girls with that figure are super rare.
