The Extraordinary, the Ordinary, and SOAP! Volume 2

On a quest to save the world, extraordinary people like the Sacred Maiden, Dragonslayer, and Prince are accompanied by... Lucia, a plain, ordinary laundrymaid with one special spell. After an incident following their cleansing of the first Cristallo Sacro, Lucia and the Knight Celes find themselves separated from the rest of the party! They head to the nearest town to stock up on supplies so they can catch up to the others as soon as possible. But Celes, wanting to hide their identities in this foreign country, tells the villagers that they're freshly eloped newlyweds!? "I can't act like your wife! They'll see right through us!"
