Summary
Yuu Tachibana, a sweets scientist who wrote Himari's favorite book, asks her to be his assistant in a live experiment to bake a giant sponge cake. Despite her initial nerves, Himari manages to provide useful input when preparing the cake batter. Despite the cake cooking properly thanks to Himari's adjustments, it ultimately collapses under its large weight. Himari blames herself, but Tachibana praises her efforts, assuring her that her feelings helped the experiment become a success. Just then, Glaive steals the cake and audience's kirakiraru to power up his Nendos. Finding the confidence to believe in herself, Himari gives the Cures science advice to help them combine their attacks and take down Glaive's Nendos. Afterwards, Himari reuses the sponge cake from the experiment to make Chick Cake Pops for everyone before discovering her crystal has changed shape just like Ciel and Aoi's.
