OB visit (Orby Homon) is an act that is mainly performed as a part of information gathering when students are looking for a job. It is so called because he visits an alumnus of his university. At the time of the internship, there are many cases in which a woman who wants to get a job suffers damage such as being sexually spoken, touched, or required to act sexually by a man who claims to be an alumnus. Most of the damage has been concealed without being revealed, and it is said that the cases that have been regarded as problems these days are still the tip of the iceberg.
