A Heart Tart? All Together As One

On her way home from school, Uzume is challenged by another member of the MDAG named Kiyoshi Kiyomizu, who overwhelms her dolls with his team's rugby formation, but she is aided by Manai and Kagami, who force Kiyoshi to retreat. Rafflesia gives Uzume a card that brings forth a special technique when master and dolls work together as one, but it appears to only summon random objects upon scanning. As Uzume trains them to work cooperatively, the objects soon take the form of pieces of a cannon, though they can't figure out how to use them, with Sasara placing the blame on Uzume. Downhearted, Uzume is approached by her friend, Komachi Seishou, who encourages her to think of what she can do for her friends.
