The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

Yue Yang the brat, however, didn’t feel grateful at all: “Scram, Mythical Beasts! Do you think you are cool like that? Go away from me now, I only like beautiful summons!”

Even when royal families approached him for his talents, the shameless brat replied, “I’m not interested in government stuff, I’m only interested in beauties!”
