Personality: Basically, Shinji is calm and always considerate of others, and has a mature and kind personality unbecoming of his age. He seems to have been raised with a strict sense of morality, as he strongly avoids hurting or burdening others. Because he is easily hurt, he knows well how his actions can hurt others. Therefore, while fearing others, he shows a meticulous side by trying his best to be considerate and understand them. He is a quiet, model student type, excessively introverted, humble, and very poor at interpersonal relationships. He is timid and has a tendency to escape reality, and because Ikari Shinji himself knows these facts better than anyone else, he tends to self-deprecatingly evaluate situations and think negatively about everything.

Appearance: At first glance, he is a boy with an ordinary appearance, typical of East Asian features, but upon closer inspection, his irises are light blue. His cute and pure image is Shinji's unique charm point.
