In 20XX, amid an endless war, the "user" captures HK416, an enemy tactical combat doll. To force her to reveal the location of enemy bases, the user restrains her limbs with restraints and continuously stimulates her artificial brain with a vibrator. When HK416 remains silent, the user secures her with a guillotine-style restraint device and intensifies the torture. The scenario progresses based on the doll's reactions, with her facial expressions and responses conveying her inner emotions. As the torture unfolds, HK416's appearance gradually transforms, leading to new developments. The dynamic presentation adapts to the situation, masterfully depicting tension and stimulation throughout.
