“You good-for-nothing bastard. You are the son of a Sword Saint, yet you dare pull such a defective Class!?”

During the〈Divine Blessing Ceremony〉of the 15-year-old Elma who came from a lineage of Sword Saints, he had manifested a commonly deemed defective class known as the Heavy Knight. He had been deprived of his position as the next head of the Edvan Household and was then exiled. The Heavy Knight class had an unbalanced status and useless skills, to top it off, it was even said to be a class cowardly and indolent people have.
But, Elma knew better—that this world was the world of the game he had used to play before—and that the Heavy Knight class was the strongest class to exist. Elma made full use of the knowledge he had in his previous life and began his efficient walkthrough of the world he was reincarnated into.

After Dean, a third rate adventurer, got surrounded by demonic beasts in the demonic labyrinth, he fled to a place where he found the strongest demon who devours power: The demon-fed sword Belzera, born to the Gluttony Empress Belzebuth. After obtaining such unexpected power, he once again aims to become a first-rate adventurer he looked up to, and delves deeper into the labyrinth. However...

I, who should have died after being hit by a car, was born again in another world.

However, I was born in a shady minor family that used magic and controlled wooden puppets called the Marren Clan.

Possessing a strong interest in magic since my previous life, I spend my time zealously studying magic to the point where even the people in the vicinity draw back.

One day, I heard I was to be married to my little sister when I turned 16 in accordance with the traditions of the Marren Clan and decided to flee to the city.

For now, since I have the strongest magic, I guess I should idle around making only enough money so that I don’t have to work for my whole life.
