Akuto Sai enters the Constant Magic Avademy, where his evaluation predicts that his future occupation will be demon king.

Akuto wants to meet with Fujiko Eto in private but he is under constant watch.

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.
