The Angels are dispatched to a dying planet to retrieve a book of wisdom before it is destroyed. However, only Milfeulle's Emblem Frame is operational and all the Angels have to travel in her Frame. After almost crash landing, Milfeulle is left to stand guard and charged with not getting into trouble. Being Milfeulle though, she gets her head stuck in a wall while chasing a squirrel. As the other Angels are ready to leave, they find Milfeulle stuck and desperately try to save her before the planet explodes, knowing that only she can pilot her Frame. As they try many methods to break Milfeulle free, Milfeulle's luck causes a headstone to destroy the wall and free her. On the way home, Milfeulle gets her Frame stuck.
