An envelope is delivered to Death Cram School. Inside contains a summons for a wellness resort. Yumi tells the four eager girls that, 'No, this is wicked,' and warns them of their excessive idleness. Shiki suggests, 'When we disagree, let's play a game of breasts‑rock‑paper‑scissors!' and emerges victorious, so everyone heads to the pool. At that moment, students from Hanzoo Academy, Homura Crimson Unit, and Hebijo Secret Girl School arrive; Asuka proposes, 'Let's enjoy ourselves today,' and they agree to a brief ceasefire. Yet, a petty dispute ignites tension, and on Yumi's idea they resolve it with a duel reminiscent of ancient ninja tactics.
