Amidst baseball and swimming clubs promoting themselves at the club activities orientation, Haru and Miyachan were overwhelmed by the sheer force of the Traditional Performing Arts Club, who appeared clad in fundoshi loincloths and hachimaki headbands and began pounding Japanese drums. They decided to join for a trial session. Visiting the clubroom together as childhood friends, they were welcomed by the club president, Makoto, who handed them loincloths saying, ‘Try tying a fundoshi!!’ Their first fundoshi left them both rock hard, and following traditional festival customs led to experiencing unknown pleasures.
