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.
