The Demon King, Brook, along with his subordinates, Franky Golem, Demon Priestess Nami, Chopadevi, and Eroslime, are the evilest things in the world. A hero must rise up to defeat the evil. These heroes are the Hero Usopp, Warrior Zoro, Mage Robin, and Hero Luffy.
Usopp claims that Luffy cannot be a hero, because Usopp is already a hero. Luffy says he'd rather be a hero, which leads Zoro to want to be a hero as well. Robin claims that if Zoro and Luffy are heroes, then she'll be a school teacher.
The group then talks to the village elder, Neptsun, who tells them about the legendary holy sword, which only a true hero can pull out of the rock. Immediately, Robin pulls it out shocking everyone, and becoming a true hero.
Meanwhile, at the Demon Castle, Demon King Brook yells for the heroes to hurry up and get them, after realizing they weren't coming.
