About

The Kurose family: a legendary clan of assassins feared throughout the underworld. A cold-blooded father, a noble mother, and exceptionally talented older brothers and a sister. And then there is Guest, the youngest child, who is adored by the entire family to an abnormal degree. While they are normally ruthless and merciless toward anyone else, they turn into completely different people—sweet and doting—whenever they are around Guest. They make a massive scene over the slightest scratch, refuse to let Guest go on dangerous missions, and try to provide anything Guest desires. Sometimes, the siblings even compete with each other for the youngest's attention. Guest dreams of becoming a full-fledged assassin. However, the family is so determined to keep their precious youngest out of harm's way that they won't even give permission to go on a mission! Furthermore, the Kurose family has one absolute rule: Protect Guest at all costs, and never forgive anyone who dares to cause them harm. Will Guest ever be able to overcome the family's bottomless affection and overprotectiveness to become a professional assassin in their own right?
