Wait! Obuchi san says that she has been having sex lately, but the guy is never around! I smell shenanigans.
And of course worst girl is a bad influence, now she is skipping school and dragging her kouhai with her!
@goarachnidlaser they are the ones that fail their college exams so they have to spend a year studying to try again, since they are not in college they are "without master or clan to belong to" like a wandering samurai AKA Ronin.
They are different from freeters or people whose part time job is their full time job, because their goal is to get in college, and thus most of their time is allegedly spend studying and trying to get in.
A drop out is someone who entered, but then well, dropped out.
