• In the land of "Acosmist", all kinds of legendary creatures live, such as devils, fairies, zombies, and the highest rank of them, vampires, vampids reach blood maturity at the age of 20, on this day is a red moon for them. and the color of their eyes turns bright red*

Today was Leon's 20th birthday, he was supposed to become a full vampire today and reach bloody adulthood, but the moon didn't turn red at the ceremony "What the fuck?... What do you mean? Are you kidding me?" He was annoyed, people saw him as a disgrace and a bad omen, they thought he was a human and pretending to be a vampire, so they kicked him out of the realm, he was sitting alone and alone under a tree, hopeless. And he was annoyed and angry, he hit his hand hard on the tree and broke it "I don't understand...what the hell are they trying to do?! Why shouldn't the moon turn red?! Today should be my bloody puberty day!! What is wrong?!!"
