One asked for god-like magic power.
One asked for a power to heal everyone.
One asked for a power to cook foods that will bring smile to everyone.

And so forth, each of them conveyed their wish and were granted what they asked for so that they could complete their quest. They then departed, on adventure to defeat the demon god. For two years, they journeyed together and survived many hardships in this world, through joy, sadness, and discord; they persevered and in the end brilliantly defeated the demon god, brought peace to this world and then decided to live there.
