Fire incidents are on the rise in Kota Hilir, and a little robot named Payapi is being hailed as a hero after he was seen helping to put out the fires. Meanwhile, a fire drill at school brings back some difficult memories for Mara, but the kids have other problems to deal with when a fire erupts in town, and they rush over to help. When Mara notices traces of strange fluids at the scene, they start to suspect the fires might not be an accident after all. The culprit is revealed when Payapi is caught trying to set Amato�s garage on fire. Rubika reveals that Payapi starts fires so he can come to the rescue and be hailed as a hero. After defeating Payapi, Amato and Pian learn the story behind Mara�s disability: she was injured while saving a child from a burning building.
