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!
Huh?
