The Festival of Heracles, the biggest event of the year, draws closer to distract the students from any chaos. However, it isn't long before Violet, Dusky, and Phantom are back in the Forest of Pan, set on revenge for the ones that killed Rally, especially Dusky. This time, they're joined by Luka and Churi, a couple of curious boys in the classroom, wondering about Dusky's sudden withdrawal and Alex's trip to the Infirmary. Meanwhile, the teachers only get more questions about why their past was locked away. With Boros and Julian's disappearance, finding the answers they need becomes a challenging task. At the same time, a new enemy rages inside the forest as the Titans push deeper toward their goal, endangering the lives of everyone around. They soon realize that the forest is more menacing than it seemed and so are the beasts within.
