We conducted an in-depth interview with three female students attending a school in a ninja village that offers a unique curriculum. The class is called 'Endurance Training,' an extracurricular activity. 'As a ninja, you may need to impersonate a doll to evade enemies during infiltration. Therefore, no matter what happens, you must not 'move' or 'make a sound.' This spirit is trained through torture. They use piston vibrators, orgasm bicycles, and even have sex with the teacher, intensely squirting fluids, but are scolded, 'Don't leak! Even in enemy territory, will you leak information?' Their immature bodies shake from continuous vaginal spasms as they endure! What modern society lacks most is this 'ninja' spirit.
