天地無用！番外編 宇宙刑事美星銀河大冒険

Caught napping while the rest of the household does chores, Mihoshi Kuramitsu takes Ayeka Jurai Masaki's jab at her Galaxy Police record personally and answers it with a story. In her version, she and her partner Kiyone Makibi crack a string of Ultra Energy Matter thefts, while Tenchi Masaki and everyone else at the Masaki house get written into the case in whatever roles suit her. This standalone OVA side story runs outside the main Ryo-Ohki continuity and plays the whole account for parody.
