Amu participated in a personal boxing training session hosted by the Minato Boxing Development Association. Wearing a simple swimsuit-like outfit, she diligently follows the trainer's instructions with serious focus. Initially hesitant when told to punch the trainer in the face, she gradually grows accustomed to the exercise. At first, she throws punches cautiously, but as the trainer repeatedly urges her to "hit me," she begins punching more freely and even seems to enjoy it. Noticing the trainer's growing arousal, she continues striking him without restraint. The aroused trainer then rushes at her, knocking her down and stomping on her. Finally, they engage in a challenge where the trainer must endure Amu's punches for one full minute—an intense battle that unfolds over approximately 40 minutes. Amu's boxing performance, blending cuteness and sexiness, is irresistible for those with a desire to be dominated and beaten.
