The Power of a Shining Star! ChibiChibi's Transformation

The founding member of the Three Lights Fanclub notices Usagi's familiarity with the Three Lights, and challenges her to a game of softball. She must win to continue associating with Seiya. After Seiya trains Usagi, the game starts. Before the final inning, Sailor Aluminum Seiren attacks the opposing team's captain. Usagi transforms to save her, but Aluminum Seiren sees her, decides that Usagi holds the true star seed, and attacks her. Chibi Chibi appears, providing the power for a stronger attack she uses to defeat the phage. Later, Usagi makes the game-winning catch.
