Fujiko sets up a meeting between Akuto and Junko to repair the damage to their relationship; he has to get past the annoying Korone, but Kena Soga shows up, wanting Akuto to make good on his promise to be friends.

Mitsuko suggests Akuto spend time in the mental discipline chamber; they come away with a mysterious map that Kena believes will show the way to pirate treasure.

Akuto, Eiko, Hiroshi and Korone enter the cemetery beneath the charnel house, where they discover proof of past conflicts; Junko, Kena and Fujiko are not far behind, trying to get to Akuto before he learns the true nature of the map's treasure.

The students take a school trip to the beach; Hiroshi is acting oddly -- his family resides on the island, where legend has it a hero will rise who can beat the demon king.

Hiroshi learns of and rejects his destiny; Hiroshi pulls a sword from a stone, which gives him heroic powers.

Fujiko obtains a demon beast egg after slaying a slug beast; Akuto does not realize that Junko actually has feelings for him.

Junko asks Akuto to come to her family's house during vacation; there is a scheme against Kena.

Lily stands outside the school to repel the clan members' attempts to destroy the demon beasts; Yamato kidaps Kena; Eiko tells Junko to take Lily out; Junko draws the family sword.

The battle begins in the presence of the gods; Akuto defeats Yamato and learns the truth, but refuses to comply with the original plan; a new semester begins at the academy, where Akuto is again projected to be the demon king.
