The World's Greatest Spirit Mage ~ I, who was mistreated for being a twin, apparently possessed the talent of the world's greatest spirit mage. It's too late for you to regret banishing me now. ~

Lux was born as a twin younger sister. In the Earl's household where Lux was born, there was a custom of despising twins, so she was sentenced to death. However, thanks to her mother's plea, she was allowed to be cared for until she turned 12 years old. However, she was not permitted to go outside and lived in the basement of the mansion. Despite being persecuted by her older sisters, Lux grew up with an unwavering spirit... and on the day she turned 12 as promised, she was banished from the house. However, the people of the Duke's household did not know. That Lux was overflowing with talent――.
