Office lady Saori overspent on a shopping trip abroad and found herself unable to pay her credit card bill, so despite initially refusing, she reluctantly agreed to participate. Once she began, an incredible amount came out—likely one of the largest volumes seen in the series. Second participant Satomi is currently job hunting and struggling financially; when she took on the challenge, she happened to have a slightly upset stomach, resulting in softer feces. Third participant Hitomi, overwhelmed by endless desires and financial strain, decided to apply despite her hesitation. During the interview, she suddenly felt an urgent need to go and had no choice but to use the human toilet right there on the spot. Though not particularly thick, the output was substantial in quantity and highly satisfying overall.
