A few weeks after the filming of "Super Transformation Cos ∞ Player" was completed. Oizumi completes a complete version of the making-of video and goes to Mizuki's house to give it to her, but Mizuki is not there. But Mizuki is not there, nor is she at the Takarazake film studio, which is in the middle of preparations for the filming of a new programme, "Galactic Transformation Galvan", which starts in April. I went to TV Taiyo, m.o.e. and the Hochiku head office, but could not see her. When they returned to the studio again, Mizuki, who thought she had finally met him, suddenly made a big announcement to the assembled crowd!
「超変身コス∞プレイヤー」撮影終了から数週間後。メイキングビデオの完全版を完成させた大泉は、それを美月に渡すべく彼女の家に向かう。だがそこに美月はいなかった。４月からの新番組、「銀河変身ギャルバン」撮影準備真っ最中の宝竹撮影所にもいない。テレビ太陽やm.o.e.、宝竹本社に行っても会うことはできなかった。再び撮影所に戻ってみると、ようやく会えたと思った美月が、集まった面々にいきなり重大発表！
