However, Elena's brother Touma gets upset and runs off the next day, believing that his family is weird. Catching up to Touma, Lala teaches him that the ways different cultures act isn't inherently weird. Just then, Tenjou, who has retrieved the Scorpio Star Color Pen, appears and transforms Touma into a giant Notray. Stating her love for her family despite its weirdness, Elena manages to recover the Scorpio pen and rescue Touma, reviving the Scorpio Star Princess in the process.
