She's been acting odd since the seaside school. And then Korone tells her to have a marriage interview with Akuto at her family's home...

The island they'd come to was Hiroshi's hometown. There was a legend there: When the demon lord revives, a beast would appear, and a hero would appear who would defeat it and the Demon Lord. It was just a legend, but Hiro was depressed. That night, his little sister Yukiko appeared and asked which of them was the Demon Lord. She believed firmly that Hiroshi was the legendary hero, and if there was a demon lord, he could be the hero as well. But she cries and runs away when Akito denies it, and is captured by a mysterious man! As they chase after her, a gigantic beast appears!

By defending Fujiko, Akuto finds himself in control of the Demon Lord's secret treasure: a dragon named Peterhausen. Despite his wishes, his reputation as a Demon Lord grows.

For some reason Korone and Keena came along, and he's caught between the two of them. However, they find a mysterious map. Keena is intrigued and wonders if it is a treasure map. The next day, Keena copies the map and it ends up all over school. It becomes the talk of the whole academy. But, Fujiko recognizes something on the map...

Akuto applies for the position of Disciplinary Committee member at Fujiko's suggestion so he can get back in Junko's good graces. But that job entails defeating those who threaten the school's discipline, and is considered perfect for the "Future Demon Lord". Akuto is suspicious of Fujiko, but his doubts disappear when she arranges for him to meet her. He goes to the designated spot, but there he's ambushed by a bunch of thugs. He defeats them, but Junko sees him beating them up and gets the idea that he's planning on making them his personal army so he can take over the school. Junko submits an application to the school to take him down, and Akuto is forced to go up against the entire student body...

On his first day, Akuto was told he was destined to become a Demon Lord. He tries his best to tell everyone it's all a misunderstanding, but everything he does just makes matters worse.

But then, the most popular girl at school, the head of the girl's dorm Etou Fujiko says that she understands him, and that she'll patch things up with Junko. However...
