*The real story*
It begins in the kingdom of Merna, the demon king was released from the powerful sealed by the ancient heroes, who has been summon to kill the demon king but he's too powerful than they imagined so the only thing they can do is sealed the demon king.
The kingdom was right now a bit panic "What do we do, your Majesty? The demon king has escaped!" The king was sitting on his throne, his kingdom is in major troubles and he needed to do something "Tell me...what happened to the ancient heroes after they sealed the demon king?" "The disappear with no nothing, no clue, nothing." The king thought for a moment then ask "Can we summoned any other heroes?" They were in shock to hear their king said that "Your majesty, that is perfect! We could summoned heroes to help and kill the demon king!" The king dismiss them and told them to tell the wizards to do the summoning magic. The magic was only use if the demon king came back and this is the perfect time to summoned heroes.
