A commander and his helper have come to the Angel Base hoping to find lost technology thinking that the Angel Brigade found many and hid them secretly in their base. The commander is greeted by Milfeulle and Vanilla. He asks Milfeulle questions to where the lost technology is but Milfeulle keeps repeating the same answer that she doesn't know what lost technology is. The commander tries to befriend her hoping that she'll tell him where the lost technology is. The commander then asks Milfeulle her to show him and his helper everyone's rooms. They finally approach Mint's safe, thinking that the lost technology is inside. When Milfeulle opens up the safe, the commander enters the safe and fires Milfeulle and Vanilla as they have completed their duty. However, they become stuck inside the safe.
