The Secret of the Pegasus! The Handsome Guardian of the Dream World

Chibiusa's dream of being an adult comes true when, due to an attack by PallaPalla, she switches ages with Usagi, who in turn wished that she was a child so she didn't have to do "hard math problems". As Chibiusa has achieved her dream, Pegasus says that he has lost sight of hers. Stating that they cannot be together, Pegasus turns to leave. Chibiusa chooses her love for Pegasus instead of her dream, breaking the spell, and shares a kiss with Helios.
