In this world, rare individuals are born with [Skills]. Nigris's party, the Silver Wings, an S-rank party, deemed him incompetent based on his Appraisal Skill, which could only measure abilities. The S-rank party, seeing only his Appraisal Skill, called Nigris a parasite and expelled him. However, Nigris had two crucial abilities: the knowledge and experience gained from his Appraisal Skill, and his Healing Magic, which he used to protect his comrades and prevent their deaths. The more he cared, the more effective his magic became, turning him into a healer who could instantly heal injuries. Determined to form a party that values and trusts each other using his Appraisal Skill, Nigris gradually gathered talented individuals, eventually creating the strongest party that no one could match.
