This movie is a remake of episode 13 in the original Lupin III series.

On a sunny day, Mihoshi Kuramitsu decides to take a peaceful nap while everyone else does chores. Sick of Mihoshi's laziness, Aeka Jurai Masaki questions her capability as a Galaxy Police Officer. Her pride wounded, Mihoshi decides to prove that she is a skilled first class detective by telling the story of how she and her partner, Kiyone Makibi, put a stop to a series of thefts involving Ultra Energy Matter. To make it more fun, Mihoshi inserts Tenchi Masaki and the others into her story. However, her fantastical tale may just demonstrate her lack of a grip on reality rather than showcase her accomplishment as a talented officer.

The main character of this show is a little red bean who dreams of being eaten.
