Yuka feels envious of Saki after discovering her crush, Takashi Sano, likes Saki. While sitting on a rock with Rinko, Yuka’s wish for transformation activates the stone’s magic, swapping Yuka and Saki’s bodies. Yuka uses Saki’s form to ask Takashi out, angering the real Saki. Attempts to reverse the spell fail, causing Natsumi and Rinko to switch instead. During a date at the aquarium, Yuka realizes Takashi truly loves Saki. Rinko intervenes before a kiss occurs. Yuka accepts the reality, and everyone returns to their original bodies. Finally, Saki sends Takashi a rejection message, ending the romantic pursuit.
