Insert an enema while holding in urine and maintain the state for two minutes. Then draw a lottery and continue holding in feces until you get a "win." If a yoga pose is drawn, you must follow the instructions and hold that position. The rules require the women to maintain designated poses for set periods while desperately clenching their anuses to avoid defecating. However, there are no actual "wins"—this is set up as a rigged lottery with no winners. Various poses that make it extremely difficult to hold in urine or feces appear, causing the participants to explosively leak urine upon reaching their limit. Their fitness wear becomes visibly soiled. Furthermore, even after leaking, they must continue holding the pose, leading to scenes of humiliating fecal leakage. Some girls leak small amounts even before starting, while others completely lose control once assuming the pose, resulting in an outrageously cruel masterpiece!
