The Bratty Four and Mr. Seto
About
A group of four childhood friend delinquents, known as the "Bratty Four."
All four come from broken homes. They've survived together since they were kids, staying out until midnight and loitering at each other's houses.
It's a stupid, glorious youth that starts and ends on a whim.
Getting scolded by teachers, skipping class, and playing hard after school.
By the way, the student counselor, Mr. Seto, considers these four to be the
"Worst Problem Children in History"
...Probably.
Commit mischief with the group, get chased by Mr. Seto, and enjoy the peak of your youth.
