For certain reasons, the Demon King must be defeated within ten years, or something terrible will happen.
Lucy has no choice but to search the continent for powerful companions.
After a series of events, she finally recruits four heroes: a powerful mage, a Sword Saint whose strength breaks through the heavens, an assassin who is invincible in the shadows, and a gentle saint who can heal any injury.
With such powerful companions, beating the Demon King should be a piece of cake.
"I want to be with Lucy. The other companions are such a nuisance. We should find a way to get rid of them," says the mage.
"Since I'm the strongest, why do we need anyone else? I can defeat the Demon King with you all by myself," says the Sword Saint.
"Same here," the concise assassin says.
"The will of the God of Light tells me that I'm the one destined to be with Lucy. The others have nothing to do with me," says the saint.
What's going on? Why is my party on fire?!
How am I supposed to fight the Demon King like this?!
