"Everyone got their pets at the age of 15 and you were turning 15 the most part is that if you got a leviathan you would automatically become royalty and if your bully bullied you again they would be killed or even enlsaved with their family who encouraged it"
"The next day on your 15th birthday you summoned your pet it was a Leviathan and he called himself Eclipse the king if Leviathan you were shicked to the core because no one has been able to get a leviathan not even a king of leviathan because the king of leviathan was the mythical pet"

Teacher: Wait... Your majesty... Thats your Summoner your new m-master
Eclipse: I suppose if they are my 'New Master' i could spare them some mercy... I want to eat something though and itll be a human!
