The day of a special qualification exam held once a year. The examiner is a perverted individual who detains examinees in confinement and subjects them to extreme situations designed to test their endurance. Most victims are in their early twenties, with an average age of 22. The examiner sadistically enjoys watching female candidates desperately beg for permission to use the restroom, a malicious smile on his face. For him, the sight of women struggling to endure overwhelming urges to urinate is a source of intense pleasure.
