Milcham: From the Ashes of Hearts

A girl of low social class goes undercover to infiltrate a prestigious high school, tasked with a perilous mission. Born and raised as an orphan, sixteen-year-old Yuuna knew to dream of having real education is vain. Living day by day in a small beach town near Kurokuma kingdom’s capital; one of the biggest and richest Kingdoms in the continent of Eilusea; was hard enough let alone having the chance to go to school. She is after all a Fuyona -the unwanted-, the lowest rank in social status in her country's caste system. One day, after a tragedy that almost killed her, suddenly a man came to her offering her a chance of a lifetime to attend the most prestigious magic and alchemy school in the kingdom. Little that she knew that she was sent into the eye of the upcoming storm that will change the whole structure of the kingdom itself.
