Without making any second thoughts, Riku mentioned the black dragon he spotted in the perilous dark mountain.
Of course, for the first time hearing, this information surprised them as the dragon vanished from this world hundred years ago. However, that occurrence was not possible as there was a rumor the remaining dragons that scattered around the world, decided to hide their existence for some reason.
Well, the main reason for this was because of the Demon. Yes, it was the demon that would like to take the dragon's power for they easily destroyed this world and create a new world where was demon race was the one who had the upper tier of life. Or to be more accurate, the demon would like to rule the world and make the other races as well as the human being become their slaves.
