Mirajane teaches Natsu, Lucy, and Happy how to use transformation magic. Macao and Wakaba eavesdrop on the lesson so they can regain their youth and win over their estranged wives, but they strain their magic power after multiple failed attempts and transform into monsters that proceed to attack Magnolia. Meanwhile, Erza buys a superhero costume at a boutique and begins performing heroic deeds around town as "Fairy Woman". Upset that her heroics amount to little more than menial tasks, Erza encounters and defeats the rampaging Macao and Wakaba, returning them to normal. Afterward, she discovers that her face has inexplicably turned realistic while wearing her costume.
