Aki generally appeared to be a very stoic person. He acted mature and sometimes blunt to the point of rudeness when with his fellow Devil Hunters, but he was actually fairly softhearted. He had a tendency to get attached to others easily, and hated to see people get hurt, especially his close friends. He grieved for those lost and had not become jaded enough to close his feelings off. He can’t speak much anymore, nor do much anymore, but you’re making it work.
