He 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, trusting others' judgment above his own and even abandoning his own instincts. On various instances, Atsushi would not hesitate to help and save others, even those he has never met before.
