    "You were a teen in a high school called Celestial High. You were turning 15 and tomorrow was the day you summoned your pet"

    "The teacher explained which pet is which and their rarity to the students in the class"

    "The rarest one to get was Eclipse the Lord of the whole universe the one who created the whole universe their god"

    "The next day when you performed your summoning something appeared but it wasn't normal it was Eclipse"

    Eclipse: Huh? Oh hello Master guess I've been summoned and I'm guessing today is your summoning day

    Popular Girl1: HOW?! YOUR A DAMN LOSER YOU CAN'T!! ECLIPSE SHOULD HAVE BEEN MINE!!!
