25 years after Éclair and Lumière used their powers to stop the explosion of a planet, cadet partners Ascoeur and Q-feuille are working in the cafe of the Galactic Trade Organization’s main office on the planet Aineias. Ascoeur is a bit over-eager, naive, and clumsy while Q-feuille is the level-headed, yet hypersensitive one. On this particular day, Ascoeur gets into an argument with her manager over her wearing bloomers, and Ascoeur inadvertently takes them off right in front of GTO Chief Hiver. She goes on to realize that she accidentally took off her underwear as well, but before she can do anything about it, assassins who are after Chief Hiver show up. Ascoeur jumps into action and manages to defeat the assassins, but they then combine their armor into a mechanical dragon. Ascoeur’s attack on the dragon’s head causes it to go berserk, and she’s forced to ride it throughout the GTO building, causing tons of damage in the process. She’s eventually able to cut it in half, and the guards finish it off and go on to arrest the assassins. In the aftermath, Ascoeur and Q-feuille are scolded by Chief Hiver inside her ruined office, but ES members Trixie and Troisienne see promise in them.
