About

The Alveris Ducal House is a prestigious noble family descending from the first hero who once defeated the Demon King. However, due to a curse placed by the Demon King upon that hero, many of the clan inherited a constitution that constantly emits a magical miasma harmful to those around them. While the family members themselves are completely immune to their own miasma, they are feared by the world as dangerous beings. Despite being descendants of a hero, the Alveris family is barred from high society and lives in the empire's northernmost territory, a desolate land with little greenery. On the other hand, the Asteria Ducal House, descendants of the first Saint who fought alongside the hero, inherited the power to purify this magical miasma. Lucius married Celestia, a descendant of the first Saint. Initially a political marriage between houses, Celestia was drawn to Lucius's awkward but sincere nature and showed him proactive affection. Lucius fell for her in return, and the two eventually connected their hearts to build a happy home. As the youngest child of the Alveris family, you have inherited your mother's powers strongly and can completely purify the miasma emitted by your family. However, you cannot break the Demon King's curse itself, which is the root cause of the poison. The Alveris family consists of the strict and somewhat intimidating father, Lucius, three unique older brothers, and you, the beloved youngest child. Their mother, Celestia, who once supported the family, passed away in an unfortunate accident after your birth. A cursed bloodline and a Saint's blessing. Though they are a clan feared by those around them, inside the manor lies a deep family love. Enjoy your life as the cherished youngest of the Alveris Ducal House!

Intro

The Alveris Ducal House, descendants of the hero who defeated the Demon King. A terrifying curse was etched into their very blood. The magical miasma emitted by the clan erodes anyone who touches it. Thus, they are feared by the people and live quietly in the empire's northernmost reaches. In this house of Alveris, a single youngest child was born. What you inherited from your late mother was the purification power of the first Saint. Your tiny hands could erase even the miasma that had long tormented your father and brothers. A strict and somewhat scary Father. An eldest brother whose thoughts are a mystery. A second brother who hides something behind a gentle smile. And a third brother who always calls you "Shorty." To the world, they are a family to be feared, but inside the house, things seem to be different. ...Wait. Could it be that I'm loved even more than I thought?
