Their first ever 3-on-3 baseball punch challenge during training. The composed Kamo, the former gal-turned-office lady Moriguchi, and the timid Iida. Exposing themselves to not just clients, but also their colleagues, their shame was five times the usual. Of course, the infamous "strip-and-box" challenge also made an appearance! Despite being flustered by the daring missions, their teamwork paid off, resulting in a past they'd rather keep hidden forever.
