Nekomi Tech is having a school festival and the Motor Club is sponsoring the beauty pageant. Among the contestants are Sayoko, Urd, and even Belldandy, whom Urd entered into the contest. Urd embarrasses Sayoko by taking a peek down her swimsuit on stage. Sayoko privately vows revenge and Urd sensing this hostility vows to make Sayoko pay for her hostility to goddesses.

After the swimsuit competition, Otaki announces that the next phase of the contest will be for the girls to make simple repairs to a broken motorcycle after picking a numbered card (which identifies the bike) and following an instruction book. Sayoko is not happy with this but can do nothing except find out from a club member which card marks the easiest bike to fix. Learning it is card number 18, she attempts to find it when she discovers that Belldandy has picked that card. She convinces Belldandy to give her the card and Belldandy selects another one.

Sayoko and Urd have a hard time figuring out what to do with their bikes while Belldandy is able to magically determine all problems with her bike. Otaki announces that the third phase of the contest involves riding the repaired bike to pick up cards which will reveal a mystery person. The first girl to return to the stage with the mystery person wins the contest. Hearing this, Sayoko rushes her repairs and takes off. Urd sees this and in frustration kicks her bike. It starts and she takes off. Belldandy is still lovingly working her bike to make it just right.

Urd and Sayoko start collecting cards before Belldandy finally completes her repairs. She sets off and all three girls discover that the mystery guy is Keiichi. Thus starts a mad race through the crowds to find Keiichi and bring him to the stage. While Urd and Sayoko find Keiichi first, Belldandy's motorcycle decides to help her because of the loving repair job he received. The bike leaps forward causing Belldandy and Keiichi to land on the stage. Now Belldandy is the official Queen of the Campus.
