Wanting to earn her own Innocent Form, Megumi decides to step up her efforts in helping others. She comes across Mami Jindaiji, a budding scientist trying to build her own rocket, and decides to help her with her research. However, Megumi ends up doing a lot of unnecessary things, including washing Mami's lab coat which she promised not to clean until she had finished her rocket, and ends up feeling she is only being a nuisance. After speaking with Seiji, Megumi instead decides to make some cookies to give Mami some encouragement. The next day, however, Oresky targets Mami and creates a Rocket Saiark, wanting to launch her rocket for himself. Determined to both protect Mami's rocket and help her reach her dream, Megumi keeps on fighting before the others arrive to help defeat the Saiark. Afterwards, Mami successfully launches her rocket, becoming more encouraged in reaching her dream, with Megumi also learning something from the experience.
