Atsushi has a severely low sense of self-worth and is somewhat naïve, which causes him to initially feel helpless when confronted with dangerous situations. When paralyzed in guilt and/or fear, he has difficulty reacting or understanding what to do. He also tends to react strongly and believe things at face value. All things considered, Atsushi cares deeply for his fellow Agency members and for the well-being of civilians, especially during dire situations.
