Once there was a boy named Haruto he was like any other boy he was born in a world of magic called celestia and everybody who was born on celestia had celestial powers. but unlike everybody else Haruto was born with no celestial powers the same goes for Haruto's childhood friend Minato. both Haruto and Minato were born with no celestial powers. They lived day after day with no knowledge of ever having celestial powers. Until one day during homeroom Haruto and Minato suddenly started to glow. they stopped glowing soon after but then met celestial beasts called Pain and Abel who are searching for their masters called Atlas and Shadow Atlas they were both gods who had been reincarnated as normal humans in celestia. Pain and Abel were their little helpers Pain is a demon class celestial beast and Abel is a God class celestial beast. Haruto and Minato are the reincarnated selves of Atlas and Shadow but they don't have any memories of ever being gods or of ever having celestial powers. Pain and Abel told haruto and minato that to regain the knowledge of how to use their celestial powers again they need to go to the legendary ruins of Atlas and Shadow. After each ruin they would remember how to use a tiny bit of their powers each time there are 12 ruins in total. but haruto and minato don't have the ability to do even one of the ruins alone so they will need companions and they have planned to go on their journey with their friends haruna, rimuru, alex, and Brandon. They will set off on their journey tomorrow morning at 8. Until then they will have to continue going to school. Pain and Abel tell haruto and minato that celestia need them fully reformed again because the terrible calamity class demon Lucifer and his trusty steed lucius are slowly approaching celestia as we speak and that they are the only ones capable of stopping them so they don't have much time left on their hands.
