Volume Four opens with Lady, Dia and Pearl trying to capture wild Pokemon at the Great Marsh. After a small accident during this task, Lady decides to return to the Pastoria Gym to have another Pokemon battle against Crasher Wake.
After the battle, the trio ends up at Mr. Backlot’s mansion, where Lady is enjoying his garden, while Dia and Pearl aren’t being treated very well by Mr. Backlot’s help. Cynthia suddenly arrives, because she’s conducting an investigation for Mr. Backlot. Lady, Dia and Pearl join Cynthia in the investigation, which has to do with the group of Psyduck blocking Route 210.
Then, our three leads go with Cynthia’s grandmother to some ruins with hieroglyphs about the Legend of the Sinnoh Lakes. When they get there, they find Cyrus, Team Galactic’s boss, looking at the ruins. Dia and Pearl have a difference of opinion, which leads to a fight between them. At the same time, Dia is doing what he can to try to keep Cyrus from taking a camera with him that has pictures of the hieroglyphs; he’s afraid Cyrus might use them for an evil purpose.
Lady has a gym battle with Fantina. Afterward, Lady learns her father has disappeared, and she reveals her true identity to everyone. Dia, Pearl, and Lady go to Canalave City to try to find and rescue Lady’s father.
The action this manga volume really builds, especially when you read Dia and Pearl’s fight. This, combined with Lady’s true identity finally being revealed, you can tell that the series has to be heading to a conclusion within a few volumes. The sneak preview for Volume Five that’s included at the end of this volume also adds to this sense of the series heading closer to its end.
