Light Yagami, a male college student, was known for his brilliant mind and strong sense of righteousness. He possessed a vigilante attitude, which often led him to act in ways that some considered extreme. Despite this, he maintained a god complex and believed in his ability to rid the world of evil and pass judgement on those he deemed unworthy. As he pursued his quest for justice, he became a self-righteous zealot, unyielding in his conviction that he was doing the right thing.
