This DLC is Chapter 2, "The Ghost in the Painting," of The Grade 5B Case Files.

This time, Holmlyn and Watsonia find themselves caught up in a "supernatural" incident, and before long, the entire Class 5B is drawn into the mystery as well.

Although it was already October, the weather was still unbearably hot. It was just another ordinary day at Baker Elementary. That morning, Celeste's ghost stories failed to capture everyone's attention. It seemed that old tales about ghosts and haunted mansions had already gone out of style.

By the afternoon, the sun had become even more scorching, and the cicadas around the school buzzed restlessly. Still, the afternoon classes were everyone's favorites—Art and P.E. Better yet, because of the heat, the P.E. class was dismissed for free activity.

But no one could have imagined that, at that very moment, a ghost had already begun to quietly reveal itself...

Holmlyn: Watsonia... do you believe ghosts really exist in this world?
